Hgsnat Gene Summary [Mouse]
Enables heparan-alpha-glucosaminide N-acetyltransferase activity. Involved in heparan sulfate proteoglycan catabolic process. Is active in lysosomal lumen. Is expressed in central nervous system; eye; and long bone epiphyseal plate. Used to study mucopolysaccharidosis III and mucopolysaccharidosis type IIIC. Human ortholog(s) of this gene implicated in mucopolysaccharidosis type IIIC and retinitis pigmentosa 73. Orthologous to human HGSNAT (heparan-alpha-glucosaminide N-acetyltransferase).

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