Predicted to enable G protein-coupled peptide receptor activity. Predicted to be involved in adenylate cyclase-modulating G protein-coupled receptor signaling pathway. Predicted to be located in plasma membrane. Expressed in M.vlpaaapp; M.vlpaapaa; M.vrpaaapp; M.vrpaapaa; and head muscle. Human ortholog(s) of this gene implicated in achalasia; inflammatory bowel disease (multiple); and isolated growth hormone deficiency type IB. Is an ortholog of several human genes including ADCYAP1R1 (ADCYAP receptor type I); GHRHR (growth hormone releasing hormone receptor); and GLP1R (glucagon like peptide 1 receptor).
