    Summary
    Predicted to enable melatonin receptor activity. Predicted to be involved in several processes, including negative regulation of cell communication; positive regulation of circadian sleep/wake cycle, non-REM sleep; and regulation of transmission of nerve impulse. Predicted to act upstream of or within circadian rhythm. Predicted to be active in plasma membrane. Is expressed in alimentary system; central nervous system; eye; and reproductive system. Human ortholog(s) of this gene implicated in type 2 diabetes mellitus. Orthologous to human MTNR1B (melatonin receptor 1B). [provided by Alliance of Genome Resources, Nov 2024]

    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.
