GRK3 (G Protein-Coupled Receptor Kinase 3), also known as beta-adrenergic receptor kinase 2 (beta-ARK2), is a member of the GRK family that phosphorylates activated G protein-coupled receptors (GPCRs). GRK3 is expressed in various tissues including brain, heart, and olfactory epithelium. In the nervous system, GRK3 regulates olfactory receptor signaling and modulates neurotransmission through GPCR desensitization. GRK3 genetic variants have been associated with psychiatric disorders and addiction, highlighting its role in neuropsychiatric conditions.
GRK3 encodes G protein-coupled receptor kinase 3, also known as beta-adrenergic receptor kinase 2. It phosphorylates activated GPCRs and promotes their desensitization. GRK3 is expressed in olfactory epithelium and brain.
Expressed in brain, particularly in olfactory bulb and cortex. Also in heart and lung.
| Disease | Variants | Inheritance | Mechanism |
