    Summary
    This gene encodes a protein that is a component of the neuronal polyglutamylase complex, which plays a role in post-translational addition of glutamate residues to C-terminal tubulin tails. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Dec 2012]

    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) contains an alternate exon in the 5' coding region compared to variant 1 and its transcription extends past a splice site that is used in variant 1, resulting in a novel 3' coding region and 3' UTR. These differences cause translation initiation at a downstream AUG and result in an isoform (5) which has a shorter N-terminus and a shorter and distinct C-terminus compared to isoform 1.
