Also known as P-REX1, phosphatidylinositol-3,4,5-trisphosphate dependent Rac exchange factor 1

Phosphatidylinositol 3,4,5-trisphosphate-dependent Rac exchanger 1 protein is a protein that in humans is encoded by the PREX1 gene.

Gene data

PREX1
Name
phosphatidylinositol-3,4,5-trisphosphate dependent Rac exchange factor 1
Type
protein-coding
Aliases
P-REX1

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.
