Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human SIK3 (QSK) sequence peptide Cat. No.: PE-04APG99

Antibody Immunogen Sequence: RRH(pT)VGV(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues R408 to V414; In the first third of the protein. This is one of the two major in vivo sites for phosphorylation of SIK3.

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: SIK3 (QSK) is a protein-serine/threonine kinase of the CAMK group and CAMKL family. It is a member of the salt-inducible kinase family. SIK3 is activated by phosphorylation on T163 by STK11 in complex with STE20-related adapter-alpha (STRAD alpha) pseudo kinase and CAB39. It is a AMPK-family kinase that is ubiquitously expressed in the cytoplasm. In ovarian cancer, overexpression of SIK3 promotes G1/S cell cycle progression and cell proliferation and may therefore function as an oncoprotein.
