We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

Determining the Structural Topology of Nephrin-Receptor-Signaling-Complexes @ Ut Southwestern Medical Center
DESCRIPTION (provided by applicant): Signaling by nephrin requires the adaptor protein, Nck, and the actin nucleation-promoting factor, N-WASP, to stimulate actin polymerization necessary for efficient glomerular function. Disruptions to this signaling pathway result in nephrotic syndromes, which are characterized by abnormal secretion of protein into urine and ultimately end-stage renal failure. Clustering of the proteins, nephrin and Nck, have been suggested to be important for efficient signaling, though a mechanistic rationale for this is lacking. Studies from our lab have identified a novel regulation of N-WASP activity through dimerization, which increases N-WASP's activity in vitro by >100- fold. We hypothesize that Nck clustering regulates N-WASP dimerization in nephrin signaling, which we propose to study. PUBLIC HEALTH RELEVANCE: The clustering of proteins has been suggested to be important for proper kidney function, by potentially regulating protein-activity. Two proteins, nephrin and Nck, are relevant to a spectrum kidney diseases that may ultimately lead to kidney failure. We propose that the clustering of the two proteins, nephrin and Nck, regulates the dimerization and activity of another protein, N-WASP, that is involved in the polymerization of actin.
