Protein

G-protein coupled receptor 3

Gene

Gpr3

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

Orphan receptor with constitutive G(s) signaling activity that activate cyclic AMP. Has a potential role in modulating a number of brain functions, including behavioral responses to stress (By similarity), amyloid-beta peptide generation in neurons (By similarity) and neurite outgrowth. Maintains also meiotic arrest in oocytes (By similarity).By similarity
