GRK6 (G Protein-Coupled Receptor Kinase 6) is a serine/threonine kinase that phosphorylates activated G protein-coupled receptors (GPCRs), promoting receptor desensitization and internalization. GRK6 is expressed in brain, heart, and immune cells. In the nervous system, GRK6 plays important roles in regulating dopaminergic, cholinergic, and adrenergic receptor signaling. GRK6 activity affects motor control, learning, and reward processing. Altered GRK6 expression is observed in Parkinson's disease and schizophrenia, suggesting potential therapeutic applications.
GRK6 encodes G protein-coupled receptor kinase 6, a serine/threonine kinase that phosphorylates activated GPCRs. It is unique among GRKs for its ability to phosphorylate receptors in the basal state. GRK6 is critical for dopaminergic receptor regulation.
Expressed in brain, particularly in striatum and cortex. Important for dopamine receptor regulation.
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| Parkinson's Disease | Variants | Complex | Dopamine receptor dysregulation |
| Schizophrenia | Variants | Complex | Altered dopaminergic signaling |
