>cd05630 STKc_GRK6 STKc_GRK6: Serine/Threonine Kinases (STKs), G protein-coupled Receptor Kinase (GRK) subfamily, GRK6 isoform, catalytic (c) domain. STKs catalyze the transfer of the gamma-phosphoryl group from ATP to serine/threonine residues on protein substrates. The GRK 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. GRKs phosphorylate and regulate G protein-coupled receptors (GPCRs), the largest superfamily of cell surface receptors which regulate some part of nearly all physiological functions. Phosphorylated GPCRs bind to arrestins, which prevents further G protein signaling despite the presence of activating ligand. There are seven types of GRKs, named GRK1 to GRK7. GRK6 is widely expressed in many tissues. t is expressed as multiple splice variants with different domain architectures. It is post-translatio
