Predicted to enable calmodulin binding activity. Predicted to be involved in glycogen metabolic process. Predicted to act upstream of or within carbohydrate metabolic process. Predicted to be located in plasma membrane. Used to study visceral heterotaxy. Human ortholog(s) of this gene implicated in glycogen storage disease and glycogen storage disease IXa. Orthologous to human PHKA2 (phosphorylase kinase regulatory subunit alpha 2).
