This gene encodes a member of the glucagon superfamily of hormones that have important roles in growth and metabolism. The encoded protein undergoes proteolytic processing to generate mature peptides that function as hypophysiotropic hormones, neurotransmitters, neuromodulators and vasoregulators. M
ice lacking the encoded protein exhibit a high rate of early mortality. The surviving adult animals lacking the encoded protein exhibit decreased anxiety, hyperactive behavior and impaired steroidogenesis. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2015]
Predicted to enable several functions, including G protein-coupled receptor activity; enzyme binding activity; and neuropeptide binding activity. Predicted to be involved in several processes, including cAMP-mediated signaling; positive regulation of inositol phosphate biosynthetic process; and posi
tive 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 cell surface. Predicted to be part of receptor complex. Predicted to be active in plasma membrane. Is expressed in several structures, including adrenal gland; alimentary system; genitourinary system; immune system; and nervous system. Orthologous to human ADCYAP1R1 (ADCYAP receptor type I). [provided by Alliance of Genome Resources, Apr 2025]
