Facts about G protein-coupled receptor kinase 5.
Phosphorylates an assortment of GPCRs, such as adrenergic receptors, muscarinic acetylcholine receptors (more specifically Gi-coupled M2/M4 subtypes), dopamine receptors and opioid receptors. In addition to GPCRs, also phosphorylates various substrates: Hsc70- interacting protein/ST13, TP53/p53, HDAC5, and arrestin-1/ARRB1.
