Enables 4-alpha-glucanotransferase activity; amylo-alpha-1,6-glucosidase activity; and carbohydrate binding activity. Involved in glycogen catabolic process; response to glucocorticoid; and response to nutrient. Located in sarcoplasmic reticulum. Used to study uremia. Human ortholog(s) of this gene implicated in glycogen storage disease III. Orthologous to human AGL (amylo-alpha-1, 6-glucosidase, 4-alpha-glucanotransferase).
