Khk Gene Summary [Mouse]
Enables ketohexokinase activity. Involved in fructose catabolic process to hydroxyacetone phosphate and glyceraldehyde-3-phosphate. Acts upstream of or within fructose metabolic process and regulation of glycogen metabolic process. Located in cytoplasm and nucleus. Is active in cytosol. Is expressed in alimentary system; central nervous system; liver; and retina. Human ortholog(s) of this gene implicated in essential fructosuria. Orthologous to human KHK (ketohexokinase).

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 Khk often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
