Expertise and Research Interests
Our work focuses on the molecular mechanisms by which insulin regulates glucose uptake and utilization in fat and muscle. The GLUT4 glucose transporter is expressed almost exclusively in these tissues, and the number and activity of these transporters at the cell surface controls the rate of glucose uptake. Insulin acts within minutes to redistribute GLUT4 glucose transporters from an intracellular location to the cell surface, thereby enhancing glucose uptake in a highly regulated manner. This action of insulin is defective in individuals with type 2 diabetes or pre-diabetic (insulin-resistant) physiology. Thus, a detailed knowledge of how insulin controls GLUT4 trafficking is essential to a full understanding of the defects underlying type 2 diabetes.
Control of GLUT4 trafficking is also of significant interest as a fundamental problem in cell biology. Unlike proteins that recycle constitutively at the plasma membrane, GLUT4 is efficiently retained within cells in the absence of insulin. The mechanisms for this retention are unclear, and GLUT4 appears to be targeted to a post-endosomal compartment that remains poorly defined. The major effect of insulin is to mobilize this pool of retained GLUT4 to the plasma membrane. Similar mechanisms may control other transporters that recycle at the plasma membrane in a homonally regulated manner.
We developed a novel and efficient functional strategy to identify proteins through which insulin regulates GLUT4 trafficking. This method relies on flow cytometry to enrich for cells stably expressing particular proteins, within an adipocyte cDNA library, that alter the proportion of GLUT4 at the plasma membrane. Using this technique we identified at least one novel protein, TUG, that controls GLUT4 trafficking, and linking hormonal regulation of GLUT4 to the action of ubiquitin-like proteins. Current work focuses on elucidating the detailed mechanism by which this protein functions. Additional projects will examine the role of this protein in organism-level physiology.
