G-protein coupled receptor for CRH (corticotropin-releasing factor), UCN (urocortin), UCN2 and UCN3. Has high affinity for 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.

The transmembrane domain is composed of seven transmembrane helices that are arranged in V-shape. Transmembrane helix 7 assumes a sharply kinked structure (By similarity).By similarity
The uncleaved pseudo signal peptide prevents receptor's oligomerization and coupling to G(i) subunits. It is also responsible for the rather low receptor localization at the plasma membrane (PubMed:22689579).1 Publication
