    Summary
    The protein encoded by this gene functions in a step-wise protein degradation process through the N-end rule pathway. This protein acts as a tertiary destabilizing enzyme that deamidates N-terminal L-Asparagine residues on proteins to produce N-terminal L-Aspartate. L-Aspartate substrates are subsequently conjugated to L-Arginine, which is recognized by specific E3 ubiquitin ligases and targeted to the proteasome. Mice with a knock-out of this gene are viable, fertile, and outwardly normal, but show impairments in spontaneous activity and spatial memory, relative to their wild-type counterparts. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2016]

    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 (8) lacks two alternate internal exons and uses an alternate splice site, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
