Acts as a GDP- dissociation stimulator protein that stimulates the GDP-GTP exchange activity of RHO-like GTPases and activates them. Mediates extracellular laminin signals to activate Rac1, contributing to neurite growth. Involved in lamellipodial formation and advancement of the growth cone of embryonic hippocampal neurons. Promotes migration of neurons in the cerebral cortex. When overexpressed, induces membrane ruffling accompanied by the accumulation of actin filaments along the altered plasma membrane (By similarity). Activates specifically RAC1, but not CDC42 and RHOA. {ECO:0000250, ECO:0000269|PubMed:10512681}. |PDZ| |PH| |RhoGEF| |Rho guanyl-nucleotide exchange factor activity| |filopodium| |guanyl-nucleotide exchange factor activity| |growth cone| |regulation of Rho protein signal transduction| |lamellipodium| |regulation of Ras protein signal transduction| |GTPase activator activity| |regulation of small GTPase mediated signal transduction| |regulation of lipid metabolic process| |positive regulation of GTPase activity| |regulation of GTPase activity| |positive regulation of apoptotic process| |positive regulation of programmed cell death| |positive regulation of cell death| |positive regulation of hydrolase activity| |regulation of hydrolase activity| |G protein-coupled receptor signaling pathway| |positive regulation of catalytic activity| |regulation of apoptotic process| |regulation of programmed cell death| |regulation of cell death| |intracellular signal transduction| |positive regulation of molecular function| |regulation of intracellular signal transduction| |membrane| \\ === CRISPR Data === No hits were found.
