Enzyme Information

2.7.11.15

[Beta-adrenergic-receptor] kinase.

based on mapping to UniProt P25098

ATP + [beta-adrenergic receptor] = ADP + [beta-adrenergic receptor] phosphate.

-!- Acts on the agonist-occupied form of the receptor; also phosphorylates rhodopsin, but more slowly. -!- Does not act on casein or histones. -!- Inhibited by Zn(2+) and digitonin but is unaffected by cyclic-AMP (cf. EC 2.7.11.14 and EC 2.7.11.16). -!- Formerly EC 2.7.1.126.
