This gene encodes a protein that belongs to a family of cytoplasmic proteins that activate the Ras-like family of Rho proteins by exchanging bound GDP for GTP. It forms a complex with the small GTP binding protein Rac1 and recruits Rac1 to membrane ruffles and to focal adhesions. Multiple alternatively spliced transcript variants encoding different isoforms have been observed for this gene. [provided by RefSeq, Mar 2016],function:Acts as a RAC1 guanine nucleotide exchange factor (GEF) and can induce membrane ruffling.,similarity:Contains 1 CH (calponin-homology) domain.,similarity:Contains 1 DH (DBL-homology) domain.,similarity:Contains 1 PH domain.,similarity:Contains 1 SH3 domain.,subunit:Interacts with PAK kinases through the SH3 domain. Interacts with GIT1 and TGFB1I1. Interacts with ITCH (By similarity). Interacts with unphosphorylated PAK1.,
