joachim-135x195.gifEvenings With Nobel Laureates
The Albany Conversation traditionally holds evening lectures in areas of fundamental interest to life sciences. For Albany 2015, the 19th Conversation, Nobel Laureate Joachim Frank , Professor, Columbia University, will deliver the keynote address on June 14, 2019 at 5;30 PM on the topic The Structure and Dynamics of Biomolecules in Their Native States. Single-particle cryogenic electron microscopy (cryo-EM) has opened the door toward a characterization of structure and dynamics of molecules in their native, hydrated state, at resolutions matching those obtained by X-ray crystallography. The "resolution revolution" following the advent of commercial direct electron detectors in 2012 broadens the range of molecules for which atomic structures can be determined. One of the significant advantages of single-particle cryo-EM compared to X-ray crystallography stems from the fact that multiple, functionally relevant structures can be retrieved all at once from the same sample, even from a continuum of states. The impact of these new developments on Molecular Medicine is expected to be far-reaching.

em-comb.png Cryo-Electron Microscopy
At the Univ. of California, Los Angeles, Tamir Gonen’s laboratory studies the structures of membrane proteins that are important in maintaining homeostasis in the brain. Understanding structure (and hence function) requires scientists to build an atomic resolution map of every atom in the protein of interest, that is, an atomic structural model of the protein of interest captured in various functional states. In 2013 Tamir unveiled the method MicroED, electron diffraction of microscopic crystals, and demonstrated that it was feasible to determine high-resolution protein structures by electron crystallography of three-dimensional crystals in an electron cryo-microscope (CryoEM). The CryoEM is used in diffraction mode for structural analysis of proteins of interest using vanishingly small crystals that are a billion times smaller in volume than what is normally used for other structural biology methods like x-ray crystallography. Sriram Subramaniam of National Institutes of Health, dwells on the recent breakthroughs in the field of CryoEM for determination of the structures of a variety of medically important macromolecular assemblies. The prospect that the determination of protein structures at atomic resolution will no longer be limited by size, or by the need for crystallization represents a significant and exciting horizon in structural biology. In his lecture, Sriram will discuss the broader context of the development of CryoEM methods for studying protein complexes, viruses and cells, and provide an overview of current progress and future directions as they relate to the development of improved therapeutic agents. Lynn Zechiedrich, Baylor College of Medicine, uses individual purified DNA minicircle topoisomers of a few hundred base pairs to understand how DNA supercoiling affects DNA structure and how the supercoiling-dependent structures affect DNA activities. Using a combination of cryo-electron microscopy and electron cryotomography, she and her research team discovered that DNA topoisomers of defined supercoiling adopt a reproducibly wide yet unique distribution of three-dimensional conformations, providing possible structural explanations for enzyme recognition. Ying Lu, Harvard Medical School, uses cryoEM to study Conformational diversity of the proteasome. The 26S proteasome mediates ubiquitin-dependent protein degradation in all eukaryotic species. Lu and his associates aim to understand how ubiquitylated substrates are recognized and processively degraded by the proteasome. Modern CryoEM technology and classification algorithms identify multiple conformations of the proteasomes, and provide important insights into these questions.

pro-dy-comb.pngProtein Dynamics in the Living Cytoplasm
In the last Conversation, the 19th, Nobel Laureate Martin Karplus dwelled on the importance of protein motions to understand their function, and traced his discovery of MD simulations in 1977 to fathom protein dynamics within a single molecule. Now we are in a position to talk about the motion and foldings within protein clusters in the crowded confinement of a living cell.Lila Gierasch, University of Massachusetts Amherst, will describe her research, carried out collaboratively with Evan Powers of Scripps, combining computational and experimental approaches to understand how the protein homeostasis network of the E. coli cytoplasm maintains the health of its proteome. This work has revealed how the coordinated action of this network facilitates the folding of proteins of different biophysical properties and minimizes protein aggregation. Gary Pielak, Univ. of North Carolina, Chapel Hill, takes up the question of protein biophysics in living cells employing innovative methods that have been developed to monitor protein stability in living cells and under physiologically-relevant conditions in vitro. Through this work, we now know that protein stability is not the same in cells as it is in buffer, and recent efforts are leading to similar conclusions about the stability of protein complexes. Gary will discuss the origin of these effects and how classical theory needs to be modified to account for them. Martin Gruebele, University of Illinois, will describe how the quinary interactions, sticking and crowding affect protein folding and protein-protein interactions in the cytoplasm. Trends from conflicting pressures of sticking and crowding will be unraveled by comparing in-cell with in vitro experiments, and new techniques to examine protein-protein interaction dynamics and thermodynamics inside cells reveal important differences to in vitro assays. Systems range from metabolic enzymes, to loose protein clusters, to the spliceosome. Martin Feig, Michigan Sate Univ, discusses the Impact of non-specific interactions in crowded cellular environments on biomolecular structure and dynamics. Crowded cellular environments result in avoidable frequent interactions between biomolecules. Large-scale computer simulations were applied to study such systems. The results indicate that weak non-specific interactions can destabilize native structures, alter binding patterns and slow down diffusional dynamics.

idp-comb.pngIntrinsically Disordered Proteins: Evolution and Function
Carl Woese, Francis Crick, and many others have suggested that the genetic code evolved from a simpler precursor having far fewer amino acids. From the analysis of the work of many researchers, Edward Trifonov developed a consensus temporal order of addition of amino acids to the original genetic code. The analysis of Trifonov’s original amino acids and his temporal order of addition by Keith Dunker and his associates at Indiana Univ, School of Medicine, suggests that the first proteins on earth were intrinsically disordered and that the addition of the later amino acids enabled the formation of structured proteins, especially enzymes. Laboratory experiments provide support for these ideas. Daniel Jarosz, Stanford, remembers the past through the new form of protein-based inheritance. In his talk, Daniel will present an emerging role for intrinsically disordered proteins in promoting the emergence and inheritance of biological traits. He will also discuss the impact of this mode of inheritance on development, disease, and evolution. Sara Bondos, Texas A & M Univ., discusses regulation of protein function via structure-disorder interactions: The Hox transcription factor family enables similar regions of the development organism to acquire unique fates.  Specific intramolecular interactions between the intrinsically disordered regions of Hox proteins and their highly conserved DNA binding homeodomains diversify the function within this critical protein family. Nicolas Fawzi, Brown University, leads a team using NMR spectroscopy, molecular simulation, microscopy, and cell assays to probe disordered protein domain assembly and function. Disordered domains of RNA binding proteins aggregate in several neurodegenerative diseases and mediate formation of functional, liquid, membraneless organelles. Nick's group probes the structure of these protein (including TDP-43, FUS, hnRNPA2) within in vitro models of these organelles, the mechanistic structural changes due to disease-causing mutations, the ability of post-translational modification to alter assembly. Elisar Barbar, Oregon State University, uses a combination of biophysical methods, structural analysis by NMR and single particle electron microscopy, and cellular transcription assays, to develop a model that proposes a concerted role of intrinsic disorder and multivalency in regulating LC8 transcription. Barbar discusses how transcription factor ASCIZ binds to multiple LC8 dimers simultaneously in both a positively and negatively cooperative fashion, enabling the formation of a dynamic equilibrium of complexes, of which low occupancy intermediates are highly populated. These observations support a novel model of autoregulation, whereby ASCIZ engages in a dynamic equilibrium of multivalent interactions that tune the level of ASCIZ transcriptional activity.

chromatin-1-comb.png Rules of Life; and Session-I: Nucleosomes, Chromatin and Higher Order Chromosome Organization - I
Dr. Manju Hingorani, Ph.D. Professor of Molecular Biology and Biochemistry, Wesleyan Univ., and program director of Molecular and Cellular Biosciences at NSF, will speak on Understanding the Rules of Life, which is one of NSF’s ten big ideas that will be supported in the coming years. The Conversation will provide quiet rooms for continued dialog after Manju’s lecture. We hope that this will be very helpful to many of the young scientists such as doctoral students, post-docs and assistant professors, in addition to the seasoned researchers.
Positioning of DNA in nucleosomes can modulate the DNA accessibility, which affects binding of histone modifiers and chromatin remodelers. The molecular modeling of variant nucleosomes is a challenging task since it requires modeling of a variant histone octamer and finding the correct rotational and translational positioning of DNA with respect to histone octamer. Anna Panchenko, National Institutes of Health, dwells on integrative approaches to determine the DNA positioning in nucleosomes at single base pair resolution and to model variant nucleosomes by combining experimental data with computational techniques. Habil Vlad Cojocaru, MPI, Munster, Germany, will present his recent efforts to explore how nucleosome dynamics modulate the binding of linker histones and transcription factors to nucleosomes. First, Vlad will show how a combination of Brownian and molecular dynamics simulations revealed an ensemble of geometries for the complex between the nucleosome core particle and linker histones. Second, he will reveal the structural basis for the binding of the pioneer transcription factor Oct4 to nucleosomes. Oct4 is a master regulator of stem cell pluripotency and is critical for cell fate transitions such as the induction of pluripotency in somatic cells. Lois Pollack, Cornell Univ., will discuss new methods to investigate the dynamic structures of DNA within nucleosome core particles. She will describe studies that examine the role of histone variants or DNA sequence on nucleosome conformation, and others that exploit triggers of conformational change ranging from the biophysical (salt) to the biological (chromatin remodelers).Beat Fierz, Ecole polytechnique fédérale de Lausanne, will describe his latest research to unravel how multivalent effector proteins control the structure and function of post-translationally modified chromatin. This research is based on protein chemistry methods to synthesize modified chromatin fibers, combined with single-molecule methods to directly detect chromatin conformational dynamics. He will further demonstrate mechanisms how structural motions in chromatin fibers enable invasion of transcription factors to enable gene transcription.

chromosome-comb.pngNucleosomes, Chromatin and Higher Order Chromosome Organization - II
Under the title “The ‘self-stirred’ genome: Bulk and surface dynamics of the chromatin globule”, Alexandra Zidovska, New York Univ., uses approaches from soft matter physics and polymer physics to study chromatin, the functional form of DNA in cells, particularly its organization and dynamics in eukaryotic cell nuclei. Recently, she developed an approach, displacement correlation spectroscopy (DCS) based on time-resolved image correlation analysis, to map chromatin dynamics simultaneously across the whole nucleus in cultured human cells. This is unprecedented, as previously only movement of single genes or foci was tracked. Using DCS she discovered that chromatin dynamics is coherent at the scale of microns and seconds, which paints a new physical picture of chromatin organization, and opens new avenues in chromatin research. Alexandra will discuss the non-equilibrium chromatin dynamics, both in bulk and at the surface of the chromatin globule. Leonid Mirny is co-director of the Center for 3D Structure and Physics of the Genome at UMass Medical School and MIT, funded by the National Institutes of Health’s 4D Nucleome Program. He is working to understand the human genome in 3D with his team at MIT in collaboration with the Dekker Lab at UMass Medical School. Using new data uncovered via Chromosome Conformation Capture (Hi-C) technology and computer simulations, the collaborators explore how the genome is organized inside a cell. Xiaowei Zhuang, Harvard Univ., will talk on in situ chromosome and transcriptome imaging in single cells. Alexander Grossberg, New York Univ., is looking at possible polymer models to study genome. Genome folding is a complex multifaceted problem.  But one way or another, chromatin fiber is a long polymer, and so some polymer models are bound to be necessary to understand the genome.  What are these useful models may still be an open question, but one still can discuss some of the candidates. 

r-loops-comb.pngR Loops and Genome Dynamics
Recent results on mechanisms of R-loop induced chromosome fragility, and implications for genome instability and repeat expansion diseases will be presented by Catherine Freudenreich at Tufts Univ. Stable R-loops have been shown to form at G-rich repeats and induce chromosome breaks and repeat length changes. At the human Ig locus in mammalian B cells the breaks are caused by the RAG endonuclease. However, the mechanisms causing R-loop dependent breaks and repeat instability at other types of repeat sequences are less well understood. Catherine’s lab recently identified cytosine deamination followed by base excision repair (BER) as one such mechanism, with an additional (and less understood) role for the Mlh1-Mlh3 nuclease. Lee Zou, Harvard Medical School, will talk about how aberrant R loop accumulation occurs in cancer cells, and how this specific vulnerability of cancer cells can be exploited in targeted therapy. Furthermore, Lee will discuss the molecular pathways that sense and respond to R loops in the human genome. Jacqueline Barlow, UC Davis, will discuss the causes and consequences of replication stress-induced fragile site breakage. Persistent R loops can act as barriers to replication fork progression, leading to replication fork collapse and DNA break formation. Dr. Barlow will discuss the impact of defective R loop removal on fragile site stability and the formation of gross chromosome rearrangements. Andrei Kuzminov, University of Illinois at Urbana-Champaign, will consider possible types of R-lesions (the DNA lesions that have integral RNA parts) on the basis of experiments with mutants deficient in removal of both R-loops and single ribonucleotides from DNA. Diverse evidence points to the critical importance of R-loops for R-lesion formation, but could R-loops be R-lesions themselves? Andrei will argue that, in contrast to R-loops, in which RNA invades homologous DNA duplex without forming covalent bonds with it, R-lesions have ribonucleotides integrated into DNA strands.

segence-comb.pngSequencing & Structural Dynamics - Single Molecules
Nanopore sequencing is a single molecule characterization method, allowing direct sequencing of stretches ranging from kilobases to even megabase long reads.  Unlike traditional sequencing-by-synthesis methods, it can distinguish covalently modified nucleotides directly through their modulation of the electrolytic current. Using this detection, Winston Timp and his associates at Johns Hopkins, have explored endogenously modified bases and performed exogenous labeling to characterize the epigenome and transcriptome. Yale Goldman, Univ. of Pennsylvania, explores single molecule structural dynamics of protein synthesis. The processive nature of protein synthsis on the ribosome makes the single molecule appoach toward delineating mechanisms especially relevant. Elementary steps of the elongation cycle are apparent with single molecule TIRF microscopy and  fluorescent  ribosomal proteins and tRNAs. We have studied mechanisms of proof-reading, translocation and the coopertaivity between the A- and E- tRNA binding sites. The order of labeled fluorescent tRNA binding also enables distinguishing mRNA and peptide sequences.

npc-comb.pngNuclear Pore Complex- Transport between the Nucleus and the Cytoplasm
Nuclear Pore Complex (NPC) is a biological "nanomachine" that controls transport between the nucleus and the cytoplasm in eukaryotic cells. Its architecture has inspired design of bio-mimetic nanochannels  capable of molecular recognition and selective transport. Anton Zilman, Univ. of Toronto, will describe the physical underpinnings of the selective permeability and the gating strategies of the NPC and polymer-functionalized nano-channels. Tijana Jovanovic-Talisman, Beckman Research Institute, City of Hope, develops and utilizes quantitative super-resolution microscopy methods to probe the mechanism of nucleocytoplasmic transport. She employs purified NPC components and isolated nuclei to elucidate binding and diffusion of proteins that drive the transport. Roderick Y.H. Lim, Biozentrum and the Swiss Nanoscience Institute. University of Basel, Switzerland, is interested in nucleocytoplasmic transport (NCT) control. They want to understand how Nuclear Pore Complexes (NPCs) together with the soluble NCT machinery (i.e., karyopherins; specifically importins and exportins) selectively regulate the rapid bidirectional traffic of molecular cargoes to and from the cell nucleus. Roderick’s interdisciplinary approach combines structural, biophysical and cellular experimentation with biomimetic validation to address this fundamentally unresolved question. Surprisingly, his recent findings suggest that karyopherins are key to controlling NPC function - as opposed to the accepted view that NPCs control karyopherin transport. Rob Coalson. Univ of Pittsburgh, provides a statistical mechanical model of transport receptor binding in the Nuclear Pore Complex. Quasi-analytical statistical mechanical models are used to predict the morphology of a polymer brush in a solution filled with nanoparticles that attract monomers of the polymer.  These model calculations are calibrated via coarse-grained Molecular Dynamics simulations.  The models are then used to analyze interactions between natively unfolded protein filaments that line the Nuclear Pore Complex and globular receptor proteins that ferry large biomolecular cargos through it.

antibio-comb.pngThe Molecular Basis of Antibiotic Action and Resistance
Under the title RNA polymerase: the Molecular Machine of Transcription, Richard H Ebright, Rutgers Univ., will describe structural (cryo-EM, X-ray crystallography) and single-molecule (nanopore tweezers, magnetic tweezers) studies of transcription initiation, elongation, termination, and regulation. Anthony Maxwell, John Innes Centre, Norwich, UK, will discuss the DNA topoisomerases: enzymes that control the topology of DNA in all cells, and which have become key targets for antibacterial chemotherapy. Detailed structural and mechanistic understanding of these enzymes has enabled elucidation of the mode of action of known antibiotics and the development of new molecules with potential as new clinical antibacterial agents. Susan M. Rosenberg, Baylor College of Medicine, dwells on: How bacteria and cancer cells regulate mutagenesis and their ability to evolve? This presentation will focus on the molecular mechanism of stress-inducible mutagenic DNA break repair in E. coli as a model for stress-inducible mutagenesis that propels infectious disease, antibiotic resistance, and other evolution. Susan considers its regulation by stress responses, demonstrates its formation of mutation hotspots near DNA breaks, and their discovery of a large gene network that underlies mutagenic break repair, most of which functions in stress sensing and signaling. They also show that mutagenesis is induced by the antibiotic ciprofloxacin, causing resistance to other antibiotics, and demonstrate the stress-response dependent mutagenesis mechanism. Regulation of mutagenesis in time and genomic space may accelerate evolution including evolution of pathogens, cancers, and drug resistance. Chris Dowson, Univ of Warwick, UK characterizes the molecular genetic attributes which are responsible for the pathogenic properties and antibiotic resistance of a diverse range of human and animal pathogens, to understand their evolution and to open up novel therapeutic strategies. He will dwell on mechanistic and structural understanding of bacterial cell walls to combat antimicrobial resistance. Helen I. Zgurskaya, Univ. of Oklahoma, dwells on kinetic and molecular determinants of antibiotic permeation barriers. The permeability barrier of Gram-negative cell envelopes is the major obstacle in the discovery and development of new antibiotics. In Gram-negative bacteria, these difficulties are exacerbated by the synergistic interaction between two biochemically distinct phenomena, the low permeability of the outer membrane and active multidrug efflux. Helen's lab has developed an approach to separate the contributions of the two mechanisms in the activities of antibiotics and applied it in the discovery of efflux pump inhibitors and analyses of structure-activity relationships for active efflux and outer membrane permeation in different Gram-negative pathogens. Nagasuma Chandra, Indian Institute of Science, Bangalore, India, will present an interactive modeling and a novel formulation of the problem of drug resistance. A genome-scale protein-protein interaction network in Mycobacterium tuberculosis is reconstructed, which has enabled a novel formulation of the problem of drug resistance, allowing Nagasuma to identify possible routes through which drug resistance could emerge in bacteria. This is a first study of its kind in the literature and the analysis provides several testable hypotheses. Jim Spencer, Univ. of Bristol, UK, will consider how beta-lactamase enzymes enable bacterial pathogens to degrade beta-lactams, still the most widely prescribed class of antibiotics. He will describe the multiple mechanisms by which different types of beta-lactamase degrade the various beta-lactam classes and how his group and collaborators are combining experimental and computational approaches to understanding these; as well as how recent progress is extending the utility of beta-lactamase inhibitors in the face of continued emergence and evolution of beta-lactamases and their variants.

drug-comb.pngDrugs: Design and Discovery
The complexity of interactions between taste receptors and their ligands is first addressed by Masha Niv, Hebrew University in Jerusalem, Israel. Bitter and sweet taste receptors are GPCRs involved not only in food choice and consumption, but also in additional physiological processes, are expressed extra-orally and present potential novel targets for asthma and other disorders. The relation between chemical structure and taste, toxicity and therapeutic potential, as well as delineation of determinants of GPCR selectivity and promiscuity, are studied via a combination of computational, sensory and cell-based techniques. Sanjeev Kumar Singh, Alagappa University, Karaikudi, India will describe the increase in mortality rate due to HIV which provides the urge for the development of potential inhibitors to combat the disease. He will also demonstrate the interpretation of the binding mode interaction with the inhibitors of HIV PR, IN and RT which provides an excellent direction to combat the viral proteins. He discusses the incorporation of computational studies useful for the identification of novel/potent antiviral with the different mechanism of action to avoid resistance and cross-resistance.Barry Honig, Columbia University, will discuss the application of three dimensional protein structure to predict protein-protein and protein-ligand structures on a genome-wide scale. Protein networks and signaling pathways are constructed and described in structural terms yielding multiple potential targets for drug intervention. Drug leads are generated via structure alignment of target proteins with proteins that form a complex with small molecules where the structure is known. An integrated software package allows for the multi-directional navigation between small molecules, proteins and networks/pathways using large genomic, structural and chemical databases.Kunal Roy, Jadavpur University, India discusses on some important aspects of validation of QSAR models with application in drug design and ecotoxicological modeling. Special emphasis is given on the reliability and confidence of predictions for new query compounds.Celia Schiffer, University of Massachusetts Medical School, Worcester, combines a variety of experimental and computational chemical and structural biology techniques to understand the molecular basis of drug resistance. Drug resistance occurs through evolution, limiting the effectiveness of many of our most potent drugs and impacting the lives of millions. This often happens under the selective pressure of therapy in infectious diseases and cancer due to their rapid evolution. Celia's new structure based paradigm of drug design minimizes chances of resistance; realizing that disrupting the drug target’s activity is necessary but not sufficient for developing a robust drug that avoids resistance. Indira Ghosh, Univ. of Delhi, India, addresses: Entrapment of flow of substrate to diversion pathway : strategy to combat persistent tuberculosis. Target based drug discovery is a dire necessity to address resistance to already known drugs in tuberculosis. The in silico work will discuss the identification of a novel target interaction using metabolic control analysis in shunt pathway, understanding the mechanism of protein-protein interactions to find the inhibitor for disruption of the specific interactions.Richard Friesner , Columbia Univ., who has pioneered free energy simulations for drug discovery, will talk on the development and application of novel methods for ab initio electronic structure calculations, including mixed quantum mechanics/molecular mechanics (QM/MM) methods.Tali E. Haran, Technion, Haifa, Israel, will speak on the expanded repertoire of mutant p53 REs and the mechanism of gain of function in cancer. Currently, several clinical trials with p53 targeting compounds are ongoing. However, the large diversity of the p53 mutation space, necessitates an in depth knowledge of the functional impact of each cancer patient’s individual mutation. Tali will discuss her recent studies on the sequence-specificity of p53 gain-of-function mutants.

nano-comb.pngDNA: Nanotechnology
The use of DNA nano devices in living systems opens this session on DNA nanotechnology. Yamuna Krishnan, Univ. of Chicago employs DNA nanodevices as fluorescent reporters that can measure chemicals within organelles of live cells. In doing so, she uncovers how the chemistry within organelles impacts organelle function and thereby cell function. Björn Högberg, of the Karolinska Institute in Stockholm will talk about rendering polyhedral in 3D on the nanoscale using a new approach to DNA origami and how these structures can be used in experiments to decipher how nanoscale distances influence cell signaling. By using DNA origami as a platform to display other molecules, his lab is investigating how nanoscale spatial effects influence a number of different biological phenomena. Hao Yan, Arizona State Univ., addresses designer DNA architectures for Programmable Self-assembly. The central task of nanotechnology is to control motions and organize matter with nanometer precision.  In this talk, Hao will present his efforts in using DNA as an information-coding polymer to program and construct DNA nano-architectures with complex geometrical features. Use of designer DNA architectures as molecular sensor, actuator and scaffolds will also be discussed. Yonggang Ke, Emory University, will talk about a new reconfigurable DNA nanostructure design that demonstrated information propagation within the artificial molecular network, the recent progress in constructing gigadalton DNA nanostructures with complex shapes, and applications in functional nanomaterials assembly.

big-data-comb.pngBig Data, Machine and Deep Learning
The director of the NIGMS Division of Biophysics, Biomedical Technology, and Computational Biosciences (BBCB) is Susan Gregurick, Ph.D. In this capacity, she oversees programs that join biology with the computer sciences, engineering, mathematics and physics. She will speak about funding opportunities and strategies related to big data, machine and deep learning at her institution. The Conversation will provide quiet rooms for continued dialog after the lecture. This should be a very rewarding experience to many of the young scientists such as doctoral students, post-docs and assistant professors, in addition to the seasoned researchers. Alán Aspuru-Guzik, Univ of Toronto, will talk about the acceleration of scientific discovery. The development of molecules and materials for a variety of applications takes up to a decade between the original inception of the idea and incorporation into a new commercial device. To accelerate the discovery process, the development of integrated "self-driving" laboratories where artificial intelligence and robotics work in tandem with high-throughput simulation methods and characterization can usher a new era of scientific productivity. He will provide an overview of the approach and discuss results from his laboratory and an international collaboration that he is involved in through Mission Innovation, a global effort to accelerate the discovery of materials for clean energy. Guowei Wei, Michigan State, will describe how to integrate advanced mathematics, such as algebraic topology, differential geometry and graph theory, with powerful machine learning, including deep learning and manifold learning, for drug design and discovery. This approach earned 10 top places out of a total 26 competitive tasks in D3R Grand Challenge 3, a community-wide competition in computer-aided drug design. Julie Mitchell, Oak Ridge National Lab will present several projects utilizing machine learning in predictive models for protein structure and interaction. A key benefit of such models is the ability to make predictions about energetic effects using descriptors that are not strictly physicochemical, such as shape complementary, packing density or surface area. Michael Roukes, Caltech, will talk about his efforts towards realizing deep proteomic profiling at the single-cell level. The approach, which is based on arrays of nanomechanical systems, provides single-molecule resolution. As it is label-free and eschews antibodies for targeted proteins, it offers prospects for true discovery work and identification of low-abundance multiproteoform complexes within the much larger cellular background of highly-expressed proteins. Gustavo Caetano-Anollés, Univ of Illinois, proposes a ‘double tale’ of accretion to rationalize the structure of biological networks. Evolutionary genomics and network biology support a ‘double tale’ of structural module creation. The theory explains the evolution of biological networks at various time frames and levels of complexity, including the emergence of metabolic networks, the rise and diversification of the proteome, the evolution of the ribosome, and change in protein loop dynamics. Remarkably, the theory was already recounted in a ~2,000 year-old papyrus from the ancient city of Panopolis in Upper Egypt that is archived at the University of Strasbourg national library.
