ARHGEF7
Rho guanine nucleotide exchange factor 7 is a protein that in humans is encoded by the ARHGEF7 gene.
ARHGEF7 is commonly known as the p21-activated protein kinase exchange factor beta (beta-PIX or βPIX), because it was identified by binding to p21-activated kinase (PAK) and also contains a guanine nucleotide exchange factor domain.
