Summary
Predicted to enable deoxyguanosine kinase activity. Involved in mitochondrial ATP synthesis coupled electron transport and negative regulation of neuron projection development. Predicted to be located in cytosol. Predicted to be active in mitochondrion. Used to study mitochondrial DNA depletion syndrome 3. Human ortholog(s) of this gene implicated in autosomal recessive progressive external ophthalmoplegia with mitochondrial DNA deletions 4; mitochondrial DNA depletion syndrome 3; mitochondrial metabolism disease; and portal hypertension. Orthologous to human DGUOK (deoxyguanosine kinase). [provided by Alliance of Genome Resources, Jul 2025]

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.
