Rabbit anti-Human ARHGDIB Polyclonal Antibody, Biotin conjugated

Uniprot Id

P52566

Target Species

Human

Target Name

ARHGDIB

Target Full Name

Rho GDP-dissociation inhibitor 2

Target Function

Regulates the GDP/GTP exchange reaction of the Rho proteins by inhibiting the dissociation of GDP from them, and the subsequent binding of GTP to them. Regulates reorganization of the actin cytoskeleton mediated by Rho family members.

Target Subcellular Location

Cytoplasm, cytosol.

Target Protein Families

Rho GDI family

Target Tissue Specificity

Detected in bone marrow, thymus and spleen.

Target Background

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]).
