== Function ==
[https://www.uniprot.org/uniprot/GRK4_HUMAN GRK4_HUMAN] 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.<ref>PMID:19520868</ref> <ref>PMID:8626439</ref>
