Description for Protein PREX1

phosphatidylinositol-3,4,5-trisphosphate-dependent Rac exchange factor 1
1 total interacting proteins; 1 platelet interacting proteins
Icon Book Platelet Evidence (proteome studies/others : 0/1)
(platelet: 1)
Summary:
The protein encoded by this gene acts as a guanine nucleotide exchange factor for the RHO family of small GTP-binding proteins (RACs). It has been shown to bind to and activate RAC1 by exchanging bound GDP for free GTP. The encoded protein, which is found mainly in the cytoplasm, is activated by phosphatidylinositol-3,4,5-trisphosphate and the beta-gamma subunits of heterotrimeric G proteins.
