Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables 1,4-alpha-glucan branching enzyme activity (using a glucosylated glycogenin as primer for glycogen synthesis). Involved in glycogen biosynthetic process. Is active in cytosol. Is expressed in eye; liver; nervous system; and skeletal muscle. Used to study glycogen storage disease IV. Human ortholog(s) of this gene implicated in glycogen storage disease IV and pulmonary tuberculosis. Orthologous to human GBE1 (1,4-alpha-glucan branching enzyme 1).
