    Summary
    This gene encodes a component of the telomerase ribonucleoprotein complex responsible for the replication and maintenance of chromosome ends. The encoded protein also plays a role in the nonsense-mediated mRNA decay (NMD) pathway, providing the endonuclease activity near the premature translation termination codon that is needed to initiate NMD. Alternatively spliced transcript variants encoding distinct protein isoforms have been described. [provided by RefSeq, Feb 2014]

    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 (3) uses an alternate internal promoter and thus differs in the 5' UTR and 5' coding region compared to variant 1. These differences cause translation initiation at a downstream AUG, and the resulting isoform (3) has a shorter N-terminus compared to isoform 1. Variants 3 and 4 encode the same protein (isoform 3).

    Suppressed Reference Sequence(s)

    The following Reference Sequences have been suppressed. Explain

    1. NM_001170957.1: Suppressed sequence

      Description
      NM_001170957.1: This RefSeq was permanently suppressed because currently there is insufficient support for the full-length exon combination of the transcript.
