Product Type Specific: Protein kinase pan-specific antibody

Antibody Code: NK197-2

Antibody Target Type: Pan-specific

Protein UniProt: P53779

Protein SigNET: P53779

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human JNK3 (MAPK10) sequence peptide Cat. No.: PE-01AXQ99

Antibody Immunogen Sequence: CAGLTFPKLFPDSLFP

Antibody Immunogen Description: Corresponds to amino acid residues A305 to P319; Pre-kinase last alpha-chain

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.

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

Scientific Background: JNK3 (MAPK10) is a protein-serine/threonine kinase of the CMGC group and MAPK family. Phosphorylation at T221 and Y223, by MAP2K4 and MAP2K7. MAP2K7, increases phosphotransferase activity. MAP2K7 phosphorylates JNK3 on T221 causing a conformational change and a large increase in Vmax. MAP2K4 then phosphorylates Y223 resulting in a further increase in Vmax. Phosphorylation at T131 inhibits phosphotransferase activity. It is inhibited by dual specificity phosphatases, such as DUSP1 and by HDAC9. The near absence of reported somatic mutations in this protein indicates that it may function as a tumour requiring protein (TRP) in many human tumours.
