Antibody Host Species: Rabbit
Antibody Immunogen Source: Human TAO1 (TAOK1) sequence peptide Cat. No.: PE-04ALF99
Antibody Immunogen Sequence: PAN(pS)FVG(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues P178 to G184; in the protein kinase catalytic domain activation T loop region between subdomains VII and VIII. S181 phosphorylation is predicted to be stimulatory for phosphotransferase activity. This is one of the major sites of in vivo phosphorylation of TAO1 based on ≥25 mass spectrometry reports recorded in PhosphoSitePlus. TAO1 is known to be phosphorylated at this site in vitro by TAO1.
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: TAO1 (Thousand-and-one amino acid kinase 1; MAP3K16; TAOK1) is a protein-serine/threonine kinase of the STE group and STE20 family. It is involved in various processes such as p38/MAPK14 stress-activated MAPK cascade, DNA damage response and regulation of cytoskeleton stability. It phosphorylates MAP2K3, MAP2K6 and MARK2, and acts as an activator of the p38 (MAPK14) stress-activated MAPK cascade by phosphorylation and activation of the upstream MKK3 and MKK6 kinases. It is involved in G protein-coupled receptor signalling to p38 (MAPK14). In response to DNA damage, it is involved in the G2/M transition DNA damage checkpoint by activating the p38 (MAPK14) stress-activated MAPK cascade, probably by mediating phosphorylation of MKK3 (MAP2K3) and MKK6 (MAP2K6). It serves as a regulator of cytoskeleton stability by phosphorylating MARK2 at Thr-208, leading to its activation and subsequent phosphorylation and detachment of MAPT/TAU from microtubules. It also regulates apoptotic morphological changes, including cell contraction, membrane blebbing and apoptotic bodies formation via activation of the JNK (MAPK8) cascade. It is highly expressed in the brain, playing a significant role in neuronal development, including migration to the cortical plate.
