Also known as D4, GDIA2, GDID4, LYGDI, Ly-GDI, RAP1GN1, RhoGDI2, Rho GDP dissociation inhibitor beta
Rho GDP-dissociation inhibitor 2 is a protein that in humans is encoded by the ARHGDIB gene. Aliases of this gene include RhoGDI2, GDID4, Rho GDI 2, and others.
Members of the Rho (or ARH) protein family (see MIM 165390) and other Ras-related small GTP-binding proteins (see MIM 179520) are involved in diverse cellular events, including cell signaling, proliferation, cytoskeletal organization, and secretion. The GTP-binding proteins are active only in the GTP-bound state. At least 3 classes of proteins tightly regulate cycling between the GTP-bound and GDP-bound states: GTPase-activating proteins (GAPs), guanine nucleotide-releasing factors (GRFs), and GDP-dissociation inhibitors (GDIs). The GDIs, including ARHGDIB, decrease the rate of GDP dissociation from Ras-like GTPases (summary by Scherle et al., 1993 [PubMed 8356058]).[supplied by OMIM, Dec 2010].
