Product Type Specific: Protein kinase pan-specific antibody

Antibody Code: NK189-2

Antibody Target Type: Pan-specific

Protein UniProt: P45984 

Protein SigNET: P45984 

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human JNK2 (MAPK9) sequence peptide Cat. No.: PE-01AXN99

Antibody Immunogen Sequence: CLFPDWIFPSESERDK

Antibody Immunogen Description: Corresponds to amino acid residues L274 to K288; 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: JNK2 (MAPK9) is a protein-serine/threonine kinase of the CMGC group and MAPK family. It is involved in the control of cell differentiation, transformation, migration, proliferation, and programmed cell death in response to stress and cytokines. It has also been implicated in preventing ubiquitination of p53.Phosphorylation of T183 and Y185 by either of two dual specificity kinases, MAP2K4 and MAP2K7, increases phosphotransferase activity. Phosphorylation of S129 also increases phosphotransferase activity. It is nhibited by dual specificity phosphatases, such as DUSP1, which target the T183 and Y185 activatory phosphorylation sites. JNK2 has been shown, in a cancer cell line to have a role in breast cancer cell motility.
