    Summary
    This gene encodes the 125-kDa catalytic subunit of DNA polymerase delta. DNA polymerase delta possesses both polymerase and 3' to 5' exonuclease activity and plays a critical role in DNA replication and repair. Alternatively spliced transcript variants have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 6. [provided by RefSeq, Mar 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.

      Transcript Variant: This variant (3) contains an alternate first exon and lacks an internal exon in the 3' region, compared to variant 4. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 4, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
