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.

PREX1 (Phosphatidylinositol-3,4,5-Trisphosphate Dependent Rac Exchange Factor 1) is a Protein Coding gene. Diseases associated with PREX1 include Gastric Tubular Adenocarcinoma. Among its related pathways are Signaling by GPCR and p75 NTR receptor-mediated signalling. Gene Ontology (GO) annotations related to this gene include enzyme binding and phospholipid binding. An important paralog of this gene is PREX2.
