Predicted to enable kinase binding activity; phosphoprotein phosphatase activity; and protein phosphatase activator activity. Predicted to be involved in negative regulation of protein localization to plasma membrane; protein dephosphorylation; and regulation of phosphate metabolic process. Located in M band and Z disc. Is expressed in several structures, including brain; gonad; hemolymphoid system gland; liver; and neural retina. Orthologous to human PPP2R5A (protein phosphatase 2 regulatory subunit B'alpha).
