Protein UniProt: Q9H0K1
Protein SigNET: SIK2
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human SIK2 (QIK) sequence peptide Cat. No.: PE-01AYQ99
Antibody Immunogen Sequence: CAQIKEHKWMLIEVPV
Antibody Immunogen Description: Corresponds to amino acid residues A263 to V277; Kinase last alpha-chain.
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: SIK2 (Salt-inducible kinase 2; QIK) is a 94 kDa protein-serine/threonine kinase of the CAMK group and CAMKL family. It is a member of the salt-inducible kinase family. It regulates insulin signaling, adipocyte differentiation, and fat/cholesterol synthesis, with high expression in skeletal muscle and adipose tissue. SIK2 may modulate the efficiency of insulin signal transduction, and affect insulin resistancy. It regulates autophagy when proteasomal function is compromised and interacts with p97/VCP to control endoplasmic reticulum-associated protein degradation (ERAD). It features a kinase domain at the N-terminal, a central SNF1-protein kinase homology (SNH) domain, and a phosphorylation domain near the C-terminal. It is activated by phosphorylation on Thr-175 by LKB1 (STK11) in complex with STE20-related adapter-alpha (STRAD alpha) pseudo kinase and CAB39. SIK2 kinase activity is regulated by an acetylation-deacetylation switch; p300/CBP-mediated acetylation at Lys-53 inhibits it, while HDAC6-mediated deacetylation restores it. SIK2 stimulates histone deacetylases export. SIK2 is a centrosome kinase required for bipolar mitotic spindle formation, and may be a potential target for therapy in ovarian cancer, where it promotes glycolysis and tumor growth via the PI3K/AKT signaling pathway.
