Antibody Type: Polyclonal

Antibody Host Species: Rabbit
Antibody Immunogen Source: Human AurKA (Aurora A, AIK, STK15) sequence peptide Cat. No.: PE-04AHD99

Antibody Immunogen Sequence: RR(pT)(pT)LCG(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues R285 to G291; In the protein kinase catalytic domain activation T loop region between subdomains VII and VIII.

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: AurA (AurKA, AIK) is a protein-serine/threonine kinase of the Other group and AUR family. It regulates cell cycle progression, and it mediates chromosomal segregation during mitosis. AurA phosphotransferase activity is greatest during mitosis. It is activated by phosphorylation at S284, T287, T288 and S342. AurA appears to be a tumour requiring protein (TRP). The active form of the protein kinase normally acts to promote tumour cell proliferation. Although AurA is not an oncoprotein, it is required for upstream oncoproteins to promote tumour formation. Its low rate of mutation and down-regulation in human cancers supports it identification as a TRP, and as a target for cancer drug development. However, the overexpression of AURA has been well documented in many malignant cancers including breast, ovarian, colon, prostate and neuroblastomas. Overexpression of AURA appears to override checkpoints in cell cycle progression leading to increased cell division and proliferation. Its phosphotransferase activity is decreased 10-fold with G198N (which also induces abnormal binding to INCENP and BIRC5), or increased with T288D. Phosphatase type I interactions could be decreased with F165A, and F346A mutations, while ubiquitination could be reduced with R205A. Autophosphorylation is inhibited with D274N, and TPX2 interactions are interrupted with a T287E mutation.
