Research Description
My research focuses on integral membrane proteins, which are essential components of various organisms. These proteins, including ion channels, receptors, and transporters, play crucial roles in fundamental biological processes like nutrient transport, neurotransmitter activity, and cellular signaling. They are also significant targets for therapeutic interventions, with approximately 70% of drugs targeting membrane proteins. While high-resolution structural studies have provided static snapshots of these proteins, they often lack insights into their dynamics and true functionality. To bridge this gap, my research program employs molecular simulation techniques that integrate static structural data with biochemical and functional assays. This approach enables a comprehensive understanding of protein function and guides computational chemistry efforts for drug design.
During my postdoctoral appointment at UCSF, I focused on three critical classes of membrane proteins: solute carrier (SLC) transporters, G-protein coupled receptors (GPCRs), and ciliary ion channels. SLC transporters facilitate the movement of small molecules, GPCRs initiate intracellular signaling in response to external cues, and ciliary GPCRs and ion channels are modulated by ciliary lipids and maintain cellular homeostasis.
During my tenure as a Staff Scientist at Lawrence Livermore Laboratory, I led computational chemistry efforts targeting oncogenic proteins, which expedited the development of a drug candidate for clinical trials. I also continued to collaborate with the Delling lab at UCSF to unravel how sterol binding to ciliary ion channels triggers cell signaling in primary cilia (R01 DK127277).
At Vanderbilt University, my research involves integrating structural modeling from the AlphaFold2 (AF2) artificial intelligence system with enhanced sampling techniques. We also incorporate native mass spectrometry, high-resolution structure, biophysical techniques, and cell-biological assays from the Mchaourab and Carrasco laboratories. Our goal is to understand how conformational changes upon substrate or lipid binding to membrane proteins, such as transporters, ion channels, and receptors, elicit downstream signaling in various cell types, including those involved in cancer, metabolic disorders, and neurological disorders. This interdisciplinary approach enables us to comprehensively investigate the impact of disease mutations on protein function, conformational changes, substrate/drug binding, and their effects on cellular biology.
