Predicted to enable G protein-coupled peptide receptor activity; enzyme binding activity; and peptide binding activity. Predicted to be involved in several processes, including activation of phospholipase C activity; cAMP-mediated signaling; and positive regulation of intracellular signal transduction. Predicted to act upstream of or within G protein-coupled receptor signaling pathway. Predicted to be located in several cellular components, including bicellular tight junction; caveola; and rough endoplasmic reticulum. Predicted to be part of receptor complex. Predicted to be active in neuron projection and plasma membrane. Is expressed in several structures, including adrenal gland; alimentary system; heart ventricle; nervous system; and testis. Orthologous to human ADCYAP1R1 (ADCYAP receptor type I). [provided by Alliance of Genome Resources, Apr 2022]
