Catalytic domain of the Protein Serine/Threonine Kinase, Serum- and Glucocorticoid-induced Kinase
Serine/Threonine Kinases (STKs), Serum- and Glucocorticoid-induced Kinase (SGK) subfamily, catalytic (c) domain. STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The SGK subfamily is part of a larger superfamily that includes the catalytic domains of other protein STKs, protein tyrosine kinases, RIO kinases, aminoglycoside phosphotransferase, choline kinase, and phosphoinositide 3-kinase. There are three isoforms of SGK, named SGK1, SGK2, and SGK3 (also called cytokine-independent survival kinase CISK). SGKs are activated by insulin and growth factors via phosphoinositide 3-kinase and PDK1. They activate ion channels, ion carriers, and the Na-K-ATPase, as well as regulate the activity of enzymes and transcription factors. SGKs play important roles in transport, hormone release, neuroexcitability, cell proliferation, and apoptosis.
