[β-adrenergic-receptor] kinase
Systematic name:
ATP:[β-adrenergic-receptor] phosphotransferase



Requires G-protein for activation and therefore belongs to the family of G-protein-dependent receptor kinases (GRKs). Acts on the agonist-occupied form of the receptor; also phosphorylates rhodopsin, but more slowly. Does not act on casein or histones. The enzyme is inhibited by Zn2+ and digitonin but is unaffected by cyclic-AMP (cf. EC, rhodopsin kinase and EC, G-protein-coupled receptor kinase).
