Summary
This gene encodes a protein that is essential for nonsense-mediated mRNA decay (NMD); a process whereby transcripts with premature termination codons are targeted for rapid degradation by a mRNA decay complex. The mRNA decay complex consists, in part, of this protein along with proteins SMG5 and UPF1. The N-terminal domain of this protein is thought to mediate its association with SMG5 or UPF1 while the C-terminal domain interacts with the mRNA decay complex. This protein may therefore couple changes in UPF1 phosphorylation state to the degradation of NMD-candidate transcripts. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Aug 2011]

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.

    Status: REVIEWED

    Description
    Transcript Variant: This variant (5) differs in the 5' UTR, lacks a portion of the 5' coding region, and initiates translation at a downstream start codon, compared to variant 1. This variant also contains an alternate in-frame exon in the 3' coding region, compared to variant 1. The encoded isoform (5) is shorter than isoform 1.

Suppressed Reference Sequence(s)

The following Reference Sequences have been suppressed. Explain

  1. NM_001350222.2: Suppressed sequence

    Description
    NM_001350222.2: This RefSeq was removed because currently there is support for the transcript but not for the protein.
  2. NM_014837.3: Suppressed sequence

    Description
    NM_014837.3: This RefSeq was permanently suppressed because it has a non-consensus splice site that does't have any mRNA support.
