Antibody Host Species: Rabbit
Antibody Immunogen Source: Human PKCa (PRKCA) sequence peptide
Antibody Immunogen Sequence: KKDVVIQDDDVESTMVEKC
Antibody Immunogen Description: Corresponds to amino acid residues K371 to K388; Kinase catalytic subdomain 3
Production Method: The immunizing peptide was produced on an A.B.I. automated peptide synthesizer. The peptide was cleaved from the synthesis resin with HF and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by amino acid 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. 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.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: PKCa (PRKCA, PKC-alpha) is a protein-serine/threonine kinase in the classical protein kinase C family. This kinase is moderate to highly expressed in most tested human tissues. It is calcium activated, and dependent on acidic phospholipids (e.g. phosphatidylserine) and diacylglycerol for full phosphotransferase activity. Fatty acids can also activate PKCa. Phosphorylation of T494, T495 and T497 increases kinase activity. Phosphorylation of S657 increases phosphotransferase activity, protects against dephosphorylation of the T497 site and degradation of PKC-alpha. Phosphorylation of T638 is not essential for catalytic activity, but it protects against dephosphorylation of the T497 site. PKCa has been identified as a fundamental regulator of cardiac contractility and Ca(2+) handling in myocytes. PKCa has been linked with the development of colon, pituitary and thyroid cancers as well as glioblastoma multiforme (GM). PKCa has been considered as an oncoprotein (OP), since during tumourigenesis, as it is strongly activated by many different tumour promoting compounds, such as phorbol esters and teleocidins. While these compounds promote binding of PKC isoforms to the plasma membrane of cells, which stimulates their phosphotransferase activity, these agents also induce rapid down-regulation of PKC isoforms. Consequently, PKCa may be actually be a tumour suppressor protein. PKCa is highly expressed in several cancers, including malignant breast cancers and gliomas. Increased expression of PKCa has been observed in adenomatous pituitaries, with highest expression in invasive pituitary tumours. A point mutation was also identified in 4 invasive pituitary tumours. Furthermore, PKCa appears to stimulate cell proliferation, because many of its direct targets, such as Raf1, Bcl2, and CSPG4, participate in growth factor signalling pathways and PKC activators induce the downstream activation of ERK1/2 (MAPK3/1) and RAP1-GAP.
