AGAP2: Proteins and Enzymes

AGAP2 (also known as centaurin-gamma1, ARF-GAP with GTP-binding protein-like, ankyrin repeat and pleckstrin homology domains 2, Phosphatidyl-inositol-3-kinase enhancer, PIKE, GTP-binding and GTPase activating protein 2 and GGAP2) is a GTPase activating protein that inactivates Arf. The expression of AGAP2 is amplified in human glioblastoma cells. AGAP2 protein binds to and activates the protein kinase Akt and prevents apoptosis of cancer cells. AGAP2 also increases motility and invasive activity of cancer cells. AGAP2 may serve as a diagnostic and therapeutic target of human cancer.
