2.7.11.16 |
| Accepted name: |
G-protein-coupled receptor kinase |
| Reaction: |
ATP + [G-protein-coupled receptor] = ADP + [G-protein-coupled receptor] phosphate |
| Other name(s): |
G protein-coupled receptor kinase; GPCR kinase; GPCRK; GRK4; GRK5; GRK6; STK16 |
| Systematic name: |
ATP:[G-protein-coupled receptor] phosphotransferase |
| Comments: |
Requires G-protein for activation and therefore belongs to the family of G-protein-dependent receptor kinases (GRKs). All members of this enzyme subfamily possess a highly conserved binding site for 1-phosphatidylinositol 4,5-bisphosphate. (cf. EC 2.7.11.14, rhodopsin kinase and EC 2.7.11.15, β-adrenergic-receptor kinase). |
