Product Type Specific: Protein kinase pan-specific antibody

Antibody Code: NK042-2

Antibody Target Type: Pan-specific

Protein UniProt: P41279

Protein SigNET: P41279

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human Cot (MAP3K8, TPL2) sequence peptide

Antibody Immunogen Sequence: CAGYFNLVRGPPTLEYG

Antibody Immunogen Description: Corresponds to amino acid residues A452 to G467; C-terminus

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.

Antibody Concentration: 1 mg/ml

Scientific Background: Cot (TPL2, MAP3K8) is a protein-serine/threonine kinase of the STE group and STE-Unique family. It is essential in the TLR4 (recognizing LPS) MAPK/ERK-mediated response in the production of pro-inflammatory cytokines. Catalytic activity of Cot is lost with the K167R, or D270A mutations. IL-1 stimulated activity is decreased with S62A. This mutation will also inhibit IL-1 stimulated phosphorylation of T290 along with MEK phosphorylation when associated with A400. Full inhibition of IL-1 induced MEK phosphorylation and partial inhibition of autophosphorylation can occur with a T290A mutation. Partial inhibition of MEK phosphorylation and autophosphorylation has occurred with a T290A or T290E mutation. Partial impairment of MEK phosphorylation induced by IL-1 has been observed with a S400A mutation. When Cot is associated with A62, a complete loss of T290 and MEK phosphorylation occurs with a S400A mutation.
