Protein Structure

UniProt Annotation

Function

G-protein coupled receptor for CRH (corticotropin- releasing factor) and UCN (urocortin). Has high affinity for CRH and UCN. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and down-stream effectors, such as adenylate cyclase. Promotes the activation of adenylate cyclase, leading to increased intracellular cAMP levels. Inhibits the activity of the calcium channel CACNA1H. Required for normal embryonic development of the adrenal gland and for normal hormonal responses to stress. Plays a role in the response to anxiogenic stimuli. {ECO:0000269PubMed:18292205, ECO:0000269PubMed:18801728, ECO:0000269PubMed:23576434, ECO:0000269PubMed:23863939}.

Subcellular Localization

Cell membrane; Multi-pass membrane protein. Endosome. Note=Agonist-binding promotes endocytosis.

Disease Associations

Tissue Specificity

Predominantly expressed in the cerebellum, pituitary, cerebral cortex and olfactory lobe. {ECO:0000269PubMed:8243652}.
