QIK (human)

Overview
QIK a serine/threonine kinase of the CAMKL family and related to AMPK. Specifically expressed in adipose tissues. Like AMPK, QIK is phosphorylated and activated by LKB1. Part of a molecular complex including TORC2 and calcineurin that regulates the effects of circulating glucose and gut hormones during feeding on TORC2-mediated gene expression. In mice, insulin promotes the phosphorylation and ubiquitin-dependent degradation of TORC2, inhibiting gluconeogenic gene expression during re-feeding. In response to insulin, Akt2 phosphorylates and activates QIK which in turn stimulates the phosphorylation and cytoplasmic translocation of TORC2 where it associates with COP1, which promotes its ubiquitination and proteasomal degradation. Phosphorylates Ser794 of IRS1 in insulin-stimulated adipocytes, potentially modulating the efficiency of insulin signal transduction. Inhibits CREB activity by phosphorylating and repressing the CREB-specific coactivators, CRTC1-3. Note: This description may include information from UniProtKB.
