Predicted to enable phospholipid scramblase activity. Predicted to be involved in plasma membrane phospholipid scrambling. Predicted to be located in plasma membrane. Expressed in body wall musculature and touch receptor neurons. Is an ortholog of several human genes including PLSCR2 (phospholipid scramblase 2); PLSCR3 (phospholipid scramblase 3); and PLSCR4 (phospholipid scramblase 4).
