Summary
Predicted to enable protein phosphatase regulator activity. Acts upstream of or within heart looping and sarcomere organization. Predicted to be part of protein phosphatase type 2A complex. Is expressed in brain; liver; muscle; pericardial region; and pleuroperitoneal region. Orthologous to human PPP2R3A (protein phosphatase 2 regulatory subunit B''alpha).
