Summary
Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in G protein-coupled receptor signaling pathway. Predicted to act upstream of or within intracellular signal transduction. Predicted to be active in plasma membrane. Human ortholog(s) of this gene implicated in Klatskin's tumor. Orthologous to human PREX2 (phosphatidylinositol-3,4,5-trisphosphate dependent Rac exchange factor 2). [provided by Alliance of Genome Resources, Apr 2022]
