Scientific Background: PKCz (PRKCZ, PKC-zeta) is a member of the AGC group of protein-serine/threonine kinase in the PKC family, and Iota subfamily. It is moderate to highly expressed in most tested human tissues. PI 3,4,5-trisphosphate activates PKCz. Phosphorylation at Y356, T410 and T560 increases PKCz kinase activity. Phosphorylation of Y356 induces interaction with 14-3-3 to increase PKCz kinase activity and facilitate its complex formation with Raf1 to activate it. Phosphorylation of S113, S148, T179, S186, S217, S218, S262, and S520 also induces interaction with 14-3-3 beta and Raf1. PKCz is found in both particulate and soluble fractions and is not activated by phorbol ester. However, overexpression of PKCz and subsequent phorbol ester treatment abolished phorbol ester-induced reduction in cell proliferation. It functions in the phosphatidylinositol 3-kinase (PI3K)and p70 S6K pathways and mitogen-activated protein (MAP) kinase cascade, and is involved in NF-kappa-B activation, mitogenic signalling, cell proliferation, cell polarity, inflammatory response and maintenance of long-term potentiation (LTP). PKCz has been linked with the development of colorectal adenocarcinomas.
