ARHGEF7
| View/Edit Human | View/Edit Mouse |
Rho guanine nucleotide exchange factor 7 is a protein that in humans is encoded by the ARHGEF7 gene.[3][4][5]
Function
Rho GTPase play a fundamental role in numerous cellular processes that are initiated by extracellular stimuli that work through G protein-coupled receptors. The encoded protein belongs to a family of cytoplasmic proteins that activate the Ras-like family of Rho proteins by exchanging bound GDP for GTP. It may form a complex with G proteins and stimulate Rho-dependent signals. This protein can induce membrane ruffling. Multiple alternatively spliced transcript variants encoding different isoforms have been described for this gene, but some of their full-length sequences have not been determined.[5]
