Background
| Function | FUNCTION: Specifically phosphorylates the activated forms of G protein-coupled receptors. GRK4-alpha can phosphorylate rhodopsin and its activity is inhibited by calmodulin; the other three isoforms do not phosphorylate rhodopsin and do not interact with calmodulin. GRK4-alpha and GRK4-gamma phosphorylate DRD3. Phosphorylates ADRB2. {ECO:0000269|PubMed:19520868, ECO:0000269|PubMed:8626439}. |
| Pathway | |
| Protein Families | Protein kinase superfamily, AGC Ser/Thr protein kinase family, GPRK subfamily |
| Tissue Specificity | Isoform 1, isoform 2, isoform 3, and isoform 4 are expressed in testis. Isoform 4 is expressed in myometrium. {ECO:0000269|PubMed:16636192, ECO:0000269|PubMed:8626439}. |
