Summary: Enables deoxyguanosine kinase activity. Acts upstream of or within dGTP metabolic process and protein phosphorylation. Located in cytosol and mitochondrion. Is expressed in central nervous system and retina.

We conclude that Dguok has a major role for the synthesis of deoxyribonucleotides for mtDNA replication particularly in the liver, similar to the human disorder. Our data also show a catabolic lipid metabolism in liver tissue of Dguok-/-.

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.

mRNA and Protein(s)

NM_001162521.2 → NP_001155993.1 deoxyguanosine kinase, mitochondrial isoform 2

See identical proteins and their annotated locations for NP_001155993.1

Status: VALIDATED

Description

Transcript Variant: This variant (2), known as dGK-3, lacks an exon in the coding region, which results in a frameshift and an early stop codon compared to variant 1. The encoded isoform (2) is shorter and has a distinct C-terminus compared to isoform 1.

NR_149734.2 RNA Sequence

Status: VALIDATED

Description

Transcript Variant: This variant (3) has multiple differences in the 3' end, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
