    Current Research and Scholarly Interests Ubiquitin 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.

  • Sui Wang, PhD

    Sui Wang, PhD

    Assistant Professor of Ophthalmology

    Current Research and Scholarly Interests Our 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 Interests Laboratory of Mechanisms in Human Immunity and Disease Pathogenesis

    Studies in our lab are aimed at defining mechanisms in human immunity and disease. We are particularly interested the hypothesis that IgG repertoire diversity leading to diversity in antibody-based signaling, is a central driver of heterogeneity in human immune functioning and susceptibility to infectious diseases. Our work is defining how diversity that exists in the IgG Fc domain repertoire among people, which we define by serum IgG subclass and Fc glycoform distributions, impacts immune processes such as vaccine responses and recruitment of effector cells. IgG subclass and Fc glycoform distributions are key regulators of immunity because these determine the structure of Fc domains within immune complexes that form during vaccination or infection. Fc structure, in turn, determines the affinity of immune complexes for various Fc receptors on effector cells. Thus, we are studying how the Fc domain repertoire of an individual impacts the quality of effector cell responses that can be recruited during immune activation and how selectivity of effector responses contributes to immunity and disease.
