| UniProt Protein Function: | 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. |

| NCBI Summary: | The protein encoded by this gene is a GTPase which belongs to the RAS superfamily of small GTP-binding proteins. Members of this superfamily appear to regulate a diverse array of cellular events, including the control of cell growth, cytoskeletal reorganization, and the activation of protein kinases. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009] |
