Current Research and Scholarly InterestsUbiquitin signaling: structure, function, and therapeutics
Ubiquitin is a small protein modifier that is ubiquitously produced in the cells and takes part in the regulation of a wide range of cellular activities such as gene transcription and protein turnover. The key to the diversity of the ubiquitin roles in cells is that it is capable of interacting with other cellular proteins either as a single molecule or as different types of chains. Ubiquitin chains are produced through polymerization of ubiquitin molecules via any of their seven internal lysine residues or the N-terminal methionine residue. Covalent interaction of ubiquitin with other proteins is known as ubiquitination which is carried out through an enzymatic cascade composed of the ubiquitin-activating (E1), ubiquitin-conjugating (E2), and ubiquitin ligase (E3) enzymes. The ubiquitin signals are decoded by the ubiquitin-binding domains (UBDs). These domains often specifically recognize and non-covalently bind to the different ubiquitin species, resulting in distinct signaling outcomes.
We apply a combination of the structural (including protein crystallography, small angle x-ray scattering, cryo-electron microscopy (Cryo-EM) etc.), biocomputational and biochemical techniques to study the ubiquitylation and deubiquitination processes, and recognition of the ubiquitin chains by the proteins harboring ubiquitin-binding domains. Current research interests including SARS-COV2 proteases and their interactions with polyubiquitin chains and ubiquitin pathways in host cell responses, with an ultimate goal of providing strategies for effective therapeutics with reduced levels of side effects.
Protein self-assembly processes and applications.
The Surface layers (S-layers) are crystalline protein coats surrounding microbial cells. S-layer proteins (SLPs) regulate their extracellular, self-assembly by crystallizing when exposed to an environmental trigger. We have demonstrated that the Caulobacter crescentus SLP readily crystallizes into sheets both in vivo and in vitro via a calcium-triggered multistep assembly pathway. Observing crystallization using a time course of Cryo-EM imaging has revealed a crystalline intermediate wherein N-terminal nucleation domains exhibit motional dynamics with respect to rigid lattice-forming crystallization domains. Rate enhancement of protein crystallization by a discrete nucleation domain may enable engineering of kinetically controllable self-assembling 2D macromolecular nanomaterials. In particular, this is inspiring designing robust novel platform for nano-scale protein scaffolds for structure-based drug design and nano-bioreactor design for the carbon-cycling enzyme pathway enzymes. Current research focuses on development of nano-scaffolds for high throughput in vitro assays and structure determination of small and flexible proteins and their interaction partners using Cryo-EM, and applying them to cancer and anti-viral therapeutics.
Multiscale imaging and technology developments.
Multimodal, multiscale imaging modalities will be developed and integrated to understand how molecular level events of key enzymes and protein network are connected to cellular and multi-cellular functions through intra-cellular organization and interactions of the key machineries in the cell. Larger scale organization of these proteins will be studied by solution X-ray scattering and Cryo-EM. Their spatio-temporal arrangements in the cell organelles, membranes, and cytosol will be further studied by X-ray fluorescence imaging and correlated with cryoEM and super-resolution optical microscopy. We apply these multiscale integrative imaging approaches to biomedical, and environmental and bioenergy research questions with Stanford, DOE national labs, and other domestic and international collaborators.

Assistant Professor of Ophthalmology
Current Research and Scholarly InterestsOur research focuses on understanding the molecular mechanisms that underlie retinal development and diseases. We utilize genetic and genomic tools to uncover how different types of retinal cells, including retinal neurons, glia and the vasculature, respond to developmental cues and disease insults at the epigenomic and transcriptional levels, and how they interact and collectively contribute to the integrity of the retina.
1. Retinal cell fate specification.
We are using genetic tools and methods, such as in vivo plasmid electroporation and CRISPR, to dissect the roles of cis-regulatory elements and transcription factors in controlling retinal cell fate specification.
2. The multicellular responses elicited by diabetes in the retina.
Diabetes can induce multicellular responses in the retina, including vascular lesions, glial dysfunction and neurodegeneration, all of which contribute to retinopathy. We are using diabetic rats as models to investigate the detailed molecular mechanisms underlying the diabetes-induced multicellular responses, and the disease mechanisms of diabetic retinopathy.
3. Molecular tools that allow for cell type-specific labeling and manipulation in vivo.
Cis-regulatory elements, such as enhancers, play essential roles in directing tissue/cell type-specific and stage-specific expression. We are interested in identifying enhancers that can drive cell type-specific expression in the retina and brain, and incorporating them into plasmid or AAV based delivery systems.

Current Research and Scholarly InterestsLaboratory of Mechanisms in Human Immunity and Disease Pathogenesis
Antibodies are a critical component of host defense. While the importance of humoral immunity has been recognized for decades, substantial gaps in knowledge remain around how antibodies function, and how their function is regulated, in vivo. Our laboratory performs studies designed to fill in these gaps, with the goal of enabling new vaccine and therapeutic strategies to prevent human disease. My interest in this area culminated from training in medicine, RNA virus biology (PhD), and molecular antibody biology (postdoctoral training). The intersection of these topics, viral immunity and disease pathogenesis, is the focus of our work. The essential question driving our research is why a small subset of people develop severe or fatal disease during viral infection while most infections result in a subclinical or mild outcome, even in at-risk populations. Our hypothesis is that the antibody signaling pathways that are engaged during viral infection through Fc gamma receptors (FcγRs) are a key driver of these distinct outcomes. We are focused on several major unknowns to address this hypothesis: How are antibody effector functions regulated in vivo and does this change in disease? How do distinct signaling pathways engaged by IgG immune complex-FcγR interactions impact host cell genetic regulation and the ultimate inflammatory/immune response? What are the tissue-specific functions that antibodies engage? How does the heterogeneity in post-translational modifications (PTMs) of human antibodies contribute to heterogeneity in viral immunity?

Current Research and Scholarly InterestsThe planar cell polarity (PCP) signaling pathway polarizes animal cells along an axis parallel to the tissue plane, and in so doing generates long-range organization that can span entire tissues. Although its core proteins and much about their interactions are known, how PCP signaling occurs at a mechanistic level remains fundamentally mysterious. In my current project I will employ novel genetic methods to dissect the logic underlying how cellular asymmetry arises at a molecular level.

Virginia D. Winn, MD, PhD
Associate Professor of Obstetrics and Gynecology (Reproductive and Stem Cell Biology)
Current Research and Scholarly InterestsThe Winn Laboratory seeks to understand the unique biological mechanisms of human placentation. While the placenta itself is one of the key characteristics for defining mammals, the human placenta is different from most available animal models: it is one of the most invasive placentas, and results in the formation of an organ comprised of cells from both the fetus and the mother. In addition to this fascinating chimerism, fetal cells are deeply involved in the remodeling of the maternal vasculature in order to redirect large volumes of maternal blood to the placenta to support the developing fetus. As such, the investigation of this human organ covers a large array of biological processes, and deals not only with understanding its endocrine function, but the physiologic process of immune tolerance, vascular remodeling, and cellular invasion.

Current Research and Scholarly InterestsMany types of blindness result from the neurons of the retina no longer being able to communicate with the brain due to injury or disease. In mammals, the adult retina cannot make new retinal ganglion cells (the neurons that connect the retina with the brain) to replace those that are lost. In my work, I aim to learn about normal development of retinal ganglion cells and, further, to regenerate new retinal ganglion cells if they are lost in adulthood.
