Gys1 Gene Summary [Mouse]
Enables alpha-1,4-glucan glucosyltransferase (UDP-glucose donor) activity and glycogen synthase activity, transferring glucose-1-phosphate. Involved in glycogen biosynthetic process. Acts upstream of or within heart development. Located in cytoplasm and inclusion body. Is active in cytosol. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in cardiovascular system disease. Orthologous to human GYS1 (glycogen synthase 1). [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 Gys1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
