Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables glycogen (starch) synthase 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).
