Product Type Specific: Protein kinase pan-specific antibody

Antibody Code: NK086-4

Antibody Target Type: Pan-specific

Protein UniProt: P52333

Protein SigNET: P52333

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human JAK3 sequence peptide Cat. No.: PE-01AUR99

Antibody Immunogen Sequence: CFTAHPEGKHHSLSFS

Antibody Immunogen Description: Corresponds to amino acid residues F1110 to S1124; C-terminus

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.

Antibody Concentration: 1 mg/ml

Scientific Background: JAK3 is a protein-tyrosine kinase of the TK group and JAKA family. Phosphorylation at T8, Y904 and Y980 increases phosphotransferase activity. Phosphorylation at Y939 also increases phosphotransferase activity and induces interaction with STAT5A. Phosphorylation at Y785 induces interaction with SH2-B-beta. Phosphorylation at Y981 inhibits phosphotransferase activity. It is involved in cytokine receptor-mediated intracellular signal transduction, including activation of an oncoprotein, PI3K. JAK3 may be an oncoprotein (OP). JAK3 mutations were commonly found in juvenile myelomonocytic leukemia from whole-exome sequencing studies from 13 individuals. JAK3 were hypothesized to be involved in the progression rather than the initiation of leukemia, and patients with mutated JAK3 were associated with poorer clinical results. Mutations in this gene have been found in blood, mouth, and ovarian cancers.
