    Summary
    Predicted to enable hormone binding activity; melatonin receptor activity; and organic cyclic compound binding activity. Predicted to be involved in adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway and negative regulation of insulin secretion. Predicted to act upstream of or within circadian rhythm. Predicted to be located in neuronal cell body. Predicted to be part of receptor complex. Predicted to be active in plasma membrane. Is expressed in several structures, including adrenal gland; alimentary system; brain; liver and biliary system; and reproductive system. Orthologous to human MTNR1A (melatonin receptor 1A).

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
