PIK3C2A Proteins

Protein Information

The Class II PI3 kinases, including PIK3C2A, phosphorylate the 3 position of PI or PI4P. Though not as well studied as the Class I PI3 kinases, the Class II enyzmes have been linked to diverse, receptor-mediated cellular processes including insulin signaling, neuronal survival, and growth factor signaling. PI3-kinases play roles in signaling pathways involved in cell proliferation, oncogenic transformation, cell survival, cell migration, and intracellular protein trafficking. This protein contains a lipid kinase catalytic domain as well as a C-terminal C2 domain, a characteristic of class II PI3-kinases. C2 domains act as calcium-dependent phospholipid binding motifs that mediate translocation of proteins to membranes, and may also mediate protein-protein interactions. The PI3-kinase activity of this protein is not sensitive to nanomolar levels of the inhibitor wortmanin. This protein was shown to be able to be activated by insulin and may be involved in integrin-dependent signaling.
