Catalytic domain of Suppressor of loss of cAMP-dependent protein kinase-like Protein Serine/Threonine Kinases
Serine/Threonine Kinases (STKs), Fission yeast Suppressor of loss of cAMP-dependent protein kinase (Sck1)-like subfamily, catalytic (c) domain. STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The Sck1-like 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. This subfamily is composed of fungal proteins with similarity to the Schizosaccharomyces pombe STK Sck1. Sck1 plays a role in trehalase activation triggered by glucose and a nitrogen source. Trehalase catalyzes the cleavage of the disaccharide trehalose to glucose. Trehalose, as a carbohydrate reserve and stress metabolite, plays an important role in the response of yeast to environmental changes.
