Description
Product Characteristics:
ARHGAP17 is a Rho GTPase-activating protein involved in the maintenance of tight junction by regulating the activity of CDC42, thereby playing a central role in apical polarity of epithelial cells. It specifically acts as a GTPase activator for the CDC42 GTPase by converting it to an inactive GDP-bound state. The complex formed with AMOT acts by regulating the uptake of polarity proteins at tight junctions, possibly by deciding whether tight junction transmembrane proteins are recycled back to the plasma membrane or sent elsewhere. RHGAP17 participates in the Ca(2+)-dependent regulation of exocytosis, possibly by catalyzing GTPase activity of Rho family proteins and by inducing the reorganization of the cortical actin filaments. Acts as a GTPase activator in vitro for RAC1.
Subcellular location: Cytoplasm, Cell membrane
Synonyms: ARHGAP17, NADRIN, Neuron associated developmentally regulated protein, Rho GTPase activating protein 17, RhoGAP interacting with CIP4 homologs protein 1, RICH 1, RICH1, WBP15, MST066, MST110, MSTP038, PP367, PP4534, Rho type GTPase activating protein 17, RhoGAP interacting with CIP4 homologs 1, RICH1B.
Target Information: RICH1 is a GTPase-activating protein (GAP). GAPs stimulate the intrinsic GTP hydrolysis of small G proteins, such as RHOA (MIM 165390), RAC1 (MIM 602048), and CDC42 (MIM 116952).[supplied by OMIM, Apr 2004]
