Hrs-2 (HGS, Hepatocyte Growth Factor-regulated tyrosine kinase substrate2, Hrs2, SNAP-25 Interacting Protein Hrs-2)
Description:
Hrs/Hgs (hepatocyte growth factor-regulated tyrosine kinase substrate) is a tyrosine-phosphorylated member of a protein family characterized by a conserved 3-phosphoinositide- interacting RING zinc finger domain, the so called FYVE finger. A variant of Hrs, Hrs-2 is an ATPase that has been shown to play a regulatory role in the docking and/or fusion of synaptic vesicles to plasma membranes through a calcium-regulated interaction with SNAP-25. Hrs-2 physically interacts with Eps15, a protein required for receptor-mediated endocytosis. The Hrs-2/Eps15 interaction is calcium dependent, inhibited by SNAP-25 and alpha-adaptin, and results in the inhibition of receptor-mediated endocytosis. Immunoelectron microscopy reveals Hrs-2 localization on the limiting membrane of multivesicular bodies, organelles in the endosomal pathway. Recent data suggest that Hrs-2 acts to provide communication between endo- and exocytic processes.
