SIK2 (Q9H0K1) - Overview - Molecular Target Synopsis


SIK2, Serine/threonine-protein kinase SIK2
Enzyme Classification
UniProt Q9H0K1

Also Known as SIK2_HUMAN, SIK2, KIAA0781, QIK, SNF1LK2

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. Interacts with and phosphorylates TORC2/CRTC2.
