Summary
Predicted to enable GTPase activator activity and guanyl-nucleotide exchange factor activity. Predicted to be involved in G protein-coupled receptor signaling pathway and regulation of signaling. 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 and cholangiocarcinoma. Orthologous to human PREX2 (phosphatidylinositol-3,4,5-trisphosphate dependent Rac exchange factor 2).
