Predicted to enable ATPase-coupled intramembrane lipid transporter activity. Predicted to be involved in Golgi organization and phospholipid translocation. Predicted to act upstream of or within binding activity of sperm to zona pellucida. Predicted to be located in acrosomal vesicle. Predicted to be integral component of membrane. Predicted to be active in plasma membrane and trans-Golgi network. Orthologous to human ATP8B3 (ATPase phospholipid transporting 8B3). [provided by Alliance of Genome Resources, Apr 2022]
