Guk1 Gene Summary [Mouse]
Enables ATP binding activity and guanylate kinase activity. Involved in purine nucleotide metabolic process. Located in cytosol and photoreceptor inner segment. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in mitochondrial DNA depletion syndrome-21. Orthologous to human GUK1 (guanylate kinase 1). [provided by Alliance of Genome Resources, Apr 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 Guk1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
