PIK3C2A mouse monoclonal antibody

Class II phosphatidylinositol 3-kinases (PI3K) contain a C-terminal C2 domain that is unique to the class II isoforms of the PI3K family. This C2 domain mediates protein and phospholipid binding acitivities. PI3K Class II α generates phosphatidylinositol 3-phosphate (PIP3) and phosphatidylinositol 3,4-bisphosphate (PI (3, 4) P2) from phosphatidylinositol and phosphatidylinositol 4-phosphate. PI3K Class II α is located in various intracellular locations such as the trans-Golgi network, endocytic compartments, clathrin-coated vesicles, and nuclear speckles. Research studies have indicated that PI3K Class II α regulates the assembly and distribution of clathrin, resulting in the modulation of clathrin-dependent trafficking and sorting within the trans Golgi network. PI3K Class II α also mediates translocation of the glucose transporter GLUT4 to the plasma membrane in response to insulin. PI3K Class II α has also been shown to regulate neurosecretory granule exocytosis and vascular smooth muscle contraction. Unlike other PI3K family members, PI3K Class II α is less sensitive to the PI3K inhibitors wortmannin and LY294002.
