Summary: This gene encodes one of the enzymes required for cellular nucleic acid biosynthesis. This enzyme catalyzes the transfer of a phosphate group from ATP to CMP, UMP, or dCMP, to form the corresponding diphosphate nucleotide. Alternate splicing results in both coding and non-coding transcript variants. [provided by RefSeq, Feb 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.

NR_046394.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (3) lacks an internal exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).

AL513322, AL607122
NR_046395.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (4) contains an alternate 5' exon and uses an alternate splice site in an internal exon, compared to variant 1. This variant is represented as non-coding because it lacks a large portion of the coding region, found in variant 1.
