Antibody Phosphosite: S262+Y263

Protein UniProt: Q05513

Protein SigNET: Q05513

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human PKCz (PRKCZ) sequence peptide Cat. No.: PE-04ARQ99

Antibody Immunogen Sequence: IGRG(pS)(pY)AKVL(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues I258 to L267; In the kinase catalytic subdomain I region

Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

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.
