Summary
The protein encoded by this gene is important in purine metabolism by converting AMP to IMP. The encoded protein, which acts as a homotetramer, is one of three AMP deaminases found in mammals. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Apr 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) lacks two alternate 5' exons and contains another compared to variant 4. The resulting isoform (4) is shorter at the N-terminus compared to isoform 1.

    See identical proteins and their annotated locations for NP_001295099.1

    Status: REVIEWED

    Description
    Transcript Variant: This variant (6) differs in the 5' UTR and lacks an exon in the 5' coding region compared to variant 4. This variant represents translation initiation at an alternate start codon compared to variant 4; the 5'-most initiation codon, as used in variant 4, is associated with a truncated ORF that would render the transcript a candidate for nonsense-mediated decay (NMD). Leaky scanning may allow translation initiation at an alternate start codon to encode an isoform (5) that is shorter and has a distinct N-terminus, compared to isoform 1.
