Summary
This gene encodes one of at least three opioid receptors in humans; the mu opioid receptor (MOR). The MOR is the principal target of endogenous opioid peptides and opioid analgesic agents such as beta-endorphin and enkephalins. The MOR also has an important role in dependence to other drugs of abuse, such as nicotine, cocaine, and alcohol via its modulation of the dopamine system. The NM_001008503.2:c.118A>G allele has been associated with opioid and alcohol addiction and variations in pain sensitivity but evidence for it having a causal role is conflicting. Multiple transcript variants encoding different isoforms have been found for this gene. Though the canonical MOR belongs to the superfamily of 7-transmembrane-spanning G-protein-coupled receptors some isoforms of this gene have only 6 transmembrane domains.

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.

    Description
    Transcript Variant: This variant (MOR-1X), also known as MOR-1R, represents use of an alternate promoter and 5' UTR, uses a downstream start codon, and uses an alternate 3' exon, compared to variant MOR-1i. The resulting isoform (MOR-1X) has a shorter N-terminus and a longer and distinct C-terminus, compared to isoform MOR-1i.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (MOR-1S) represents use of an alternate promoter and 5' UTR, uses a downstream start codon, and lacks two alternate internal exons, compared to variant MOR-1i. The resulting isoform (MOR-1S) has a shorter N-terminus and a shorter and distinct C-terminus, compared to isoform MOR-1i. An in-frame, upstream AUG is present that would extend the N-terminus by 62-aa, but the longer N-terminus is not annotated to conform to the annotation commonly used in the literature.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (MOR-1K2) represents use of an alternate promoter and 5' UTR and uses a downstream start codon, compared to variant MOR-1i. The resulting isoform (MOR-1G1) has a shorter N-terminus, compared to isoform MOR-1i. Variants MOR-1G1, MOR-1K1, and MOR-1K2 encode the same isoform (MOR-1G1).

    Status: REVIEWED

    Description
    Transcript Variant: This variant (MOR-1W; also known as mu3-like and MOR-1A delta) represents use of an alternate promoter and 5' UTR, uses a downstream start codon, and uses an alternate 3' exon, compared to variant MOR-1i. The resulting isoform (MOR-1W) has a shorter N-terminus and a shorter and distinct C-terminus, compared to isoform MOR-1i.

  1. NR_104348.1 RNA Sequence

    Status: REVIEWED

    Description
    Transcript Variant: This variant (MOR-1Y3; also known as MOR-1V) represents use of an alternate promoter and contains an alternate internal exon, compared to variant MOR-1i. This variant is represented as non-coding because the use of the 5'-most translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
