WebView/Edit Mouse. G-protein-coupled receptor kinase 2 (GRK2) is an enzyme that in humans is encoded by the ADRBK1 gene. [5] GRK2 was initially called Beta-adrenergic receptor kinase (βARK or βARK1), and is a member of the G protein-coupled receptor kinase subfamily of the Ser/Thr protein kinases that is most highly similar to GRK3 … WebMay 14, 2024 · We found that GRK-mediated phosphorylation involves several serine and threonine residues on the C-terminus and ICL3. Mutation of these residues to alanine or valine, respectively, abolishes DA-induced D1R phosphorylation and severely impairs β-arrestin recruitment, but causes little effect on G protein-mediated signaling. healow thundermist
