SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic,vesicle
text	membrane-bound vesicles

basic FUNCTION	regulating 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
	metastasis suppressor gene and its targets, endothelin-1 and Neuromedin U are excellent potential targets for therapeutic intervention in the metastatic cascade (Harding 2007)
	abundantly expressed in haematopoetic cells and possibly plays a role in the onset of apoptosis (Ma 2007)
	suppressor of metastasis in human bladder cancer (Wu 2009)
	inhibit the activation of small GTPases of the Rho family by sequestering the GTPases in the cytosol and blocking activation by guanine nucleotide exchange factors (GEFs) (Wu 2009)
	regulator of Rho family GTPase (Cho 2009)
	involved in gastric tumor growth and metastasis (Cho 2009)

protein

endothelin-1 and Neuromedin U are two molecular effectors of ARHGGDIB signaling (Harding 2007)

REGULATION

Other

phosphorylation by SRC enhances ARHGDIB metastasis suppression and that loss of SRC relieves metastasis suppression in tumor cells that maintain ARHGDIB expression (Wu 2009)
