Résumé UniProt
Seems to play a role in the regulation of RhoA GTPase by guanine nucleotide-binding alpha-12 (GNA12) and alpha-13 (GNA13) subunits (PubMed:9641915, PubMed:9641916). Acts as GTPase-activating protein (GAP) for GNA12 and GNA13, and as guanine nucleotide exchange factor (GEF) for RhoA GTPase (PubMed:9641915, PubMed:9641916, PubMed:8810315, PubMed:30521495). Activated G alpha 13/GNA13 stimulates the RhoGEF activity through interaction with the RGS-like domain (PubMed:9641916). This GEF activity is inhibited by binding to activated GNA12 (PubMed:9641916). Mediates angiotensin-2-induced RhoA activation (PubMed:20098430).
Résumé Entrez
Rho GTPases play a fundamental role in numerous cellular processes that are initiated by extracellular stimuli that work through G protein coupled receptors. The encoded protein may form complex with G proteins and stimulate Rho-dependent signals. Multiple alternatively spliced transcript variants have been found for this gene, but the full-length nature of some variants has not been defined.
Spécificité tissulaire
Ubiquitously expressed.
Implication dans la maladie
Immunodeficiency 62: An autosomal recessive, primary immunologic disorder characterized by recurrent severe respiratory tract infections and bronchiectasis, due to antibody deficiency. Affected individuals have an abnormal B cell immunophenotype, with low levels of circulating memory B cells.
Modification post-traductionnelle
Phosphorylated by PKCA. Angiotensin-2 induced Tyr-738 phosphorylation is mediated by JAK2.
Localisation cellulaire
Cytoplasm. Membrane.
Translocated to the membrane by activated GNA13 or LPA stimulation.
