| GenBank Protein ID | |
| GenBank Nucleotide ID | |
| Protein Name | Phosphatidylinositol 3,4,5-trisphosphate-dependent Rac exchanger 1 protein (P-Rex1) (PtdIns(3,4,5)-dependent Rac exchanger 1) |
| Gene Name | PREX1; KIAA1415 |
| Organism | Homo sapiens |
| NCBI Taxa ID | 9606 |
| Functional Description | Functions as a RAC guanine nucleotide exchange factor (GEF), which activates the Rac proteins by exchanging bound GDP for free GTP. Its activity is synergistically activated by phosphatidylinositol 3,4,5-trisphosphate and the beta gamma subunits of heterotrimeric G protein. May function downstream of heterotrimeric G proteins in neutrophils. |
