RAC1 (human)

Overview
RAC1 a plasma membrane-associated member of the Rho-GTPase family. Plays a key role in cytoskeletal reorganization, membrane trafficking, transcriptional regulation and cell growth and development. GTP binding stimulates its activity. Phosphorylation by Akt may inhibit GTP binding of Rac1, therefore attenuating the downstream signal transduction pathway. Found in a trimeric complex composed of DOCK1 and ELMO1, which plays a central role in phagocytosis of apoptotic cells. Two alternatively spliced isoforms have been described. Note: This description may include information from UniProtKB.
