Summary
This gene encodes a nucleotidase that catalyzes the dephosphorylation of the 5' deoxyribonucleotides (dNTP) and 2'(3')-dNTP and ribonucleotides, but not 5' ribonucleotides. Of the different forms of nucleotidases characterized, this enzyme is unique in its preference for 5'-dNTP. It may be one of the enzymes involved in regulating the size of dNTP pools in cells. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Nov 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 (2) lacks an in-frame coding exon, and uses an alternate in-frame acceptor splice site at the 3' terminal exon compared to variant 1. This results in a shorter isoform (2) missing an internal protein segment compared to isoform 1.

RNA

  1. NR_045513.2 RNA Sequence

    Status: REVIEWED

    Description
    Transcript Variant: This variant (3) uses alternate acceptor and donor splice sites at an internal exon compared to variant 1. It is represented as non-coding because the use of the 5'-most supported translational start codon as used in variant 1, renders this transcript a candidate for nonsense-mediated mRNA decay (NMD).
