Galk1 Gene Summary [Mouse]
Enables galactokinase activity. Involved in galactose catabolic process via UDP-galactose, Leloir pathway. Acts upstream of or within galactitol metabolic process and glycolytic process from galactose. Predicted to be located in cytoplasm. Predicted to be active in cytosol. Is expressed in several structures, including alimentary system; cardiovascular system; integumental system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in cataract and galactokinase deficiency. Orthologous to human GALK1 (galactokinase 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 Galk1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
