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.
