Dguok Gene Summary [Mouse]
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. 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]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Dguok often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
