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.This antibody was also subject to negative purification over phosphotyrosine-agarose.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: TTK (ESK) is a protein-serine/threonine kinase of the Other group and TTK family. It is a dual specificity protein kinase that can phosphorylate serine, threonine, and tyrosine residues and has a role in cell cycle progression through regulating centrosome duplication during S-phase. This function was CDK2-mediated by direct activation of TTK.. Through CDCA8 phosphorylation TTK can modulate AurKB at the centromere to align the chromosomes. Phosphorylation of S582, T675, T676, T686, and S742 increases phosphotransferase activity. Phosphorylation of T806 inhibits phosphotransferase activity. TTK is a dual-specificity protein kinase with activity toward serine, threonine and tyrosine residues. TTK was found to have a role Overexpression or dysregulation of TTK activtiy may promote cancer through aberrant duplication of centrosomes and promotiong of aneuploidy. Mutations in TTK are highly correlated in the development of microsatellite-unstable colorectal cancers. TTK is linked to pancreatic ductal adenocarcinoma (PDAC), and important in the growth and proliferation of PDAC cancer cells. Triple Negative Breast Cancer (TNBC) is a highly aggressive form of cancer and TTK is consistently upregulated in TNBC tissues.
