Description:	NIH Neuroscience Series Seminar Our lab investigates the role played by cytoskeletal proteins in maintaining cellular homeostasis and the mechanistic basis of cytoskeleton-associated neurological, metabolic, and muscular disorders. We seek to understand how the assembly and dynamic coordination of cytoskeletal networks in specialized cell types contribute to the regulation of signal transduction, intracellular trafficking, cell motility, membrane dynamics, and cellular metabolism. Our current projects center on the cytoskeleton-associated families of proteins ankyrins, spectrins, and associated partners. Ankyrins act as micron-scale organizers of functionally related membrane transporters and cell adhesion proteins. Ankyrin-B, an ankyrin family member, is a regulator of intracellular transport in multiple cell types. Ankyrins are coupled to arrays of partnering spectrins, which confer mechanical resiliency to cell membranes. In mammalians, ankyrins and spectrins are widely expressed across multiple tissues, where they serve specialized functions. However, we do not fully understand the molecular mechanisms underlying these functions, their physiological consequences, or how their dysregulation cause disease. We are currently studying the neurobiological and metabolic roles of ankyrins, spectrins, and associated partners.
