Protein: Serine/threonine-protein kinase SIK2 (Q9H0K1)
Organism: Homo sapiens (Human)
Function: Serine/threonine-protein kinase that plays a role in many biological processes such as fatty acid oxidation, autophagy, immune response or glucose metabolism. Phosphorylates 'Ser-794' of IRS1 in insulin-stimulated adipocytes, potentially modulating the efficiency of insulin signal transduction. Inhibits CREB activity by phosphorylating and repressing TORCs, the CREB-specific coactivators. Phosphorylates EP300 and thus inhibits its histone acetyltransferase activity. In turn, regulates the DNA-binding ability of several transcription factors such as PPARA or MLXIPL. Also plays a role in thymic T-cell development (By similarity)
Subcellular location: Cytoplasm. Endoplasmic reticulum membrane
