== Function == | |||
[https://www.uniprot.org/uniprot/CRFR2_HUMAN CRFR2_HUMAN] 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. | |||

== Publication Abstract from PubMed == | |||
The ability to couple with multiple G protein subtypes, such as G(s), G(i/o), or G(q/11), by a given G protein-coupled receptor (GPCR) is critical for many physiological processes. Over the past few years, the cryo-EM structures for all 15 members of the medically important class B GPCRs, all in complex with G(s) protein, have been determined. However, no structure of class B GPCRs with G(q/11) has been solved to date, limiting our understanding of the precise mechanisms of G protein coupling selectivity. Here we report the structures of corticotropin releasing factor receptor 2 (CRF2R) bound to Urocortin 1 (UCN1), coupled with different classes of heterotrimeric G proteins, G(11) and G(o). We compare these structures with the structure of CRF2R in complex with G(s) to uncover the structural differences that determine the selective coupling of G protein subtypes by CRF2R. These results provide important insights into the structural basis for the ability of CRF2R to couple with multiple G protein subtypes. | |||
