Predicted to enable phosphatidylethanolamine flippase activity and phosphatidylserine flippase activity. Involved in phospholipid translocation; positive regulation of B cell differentiation; and pre-B cell differentiation. Predicted to be integral component of plasma membrane. Predicted to be active in several cellular components, including endoplasmic reticulum; recycling endosome; and trans-Golgi network. Is expressed in choroid invagination; diencephalon roof plate; and metencephalon part of 4th ventricle choroid plexus. Human ortholog(s) of this gene implicated in X-linked congenital hemolytic anemia. Orthologous to human ATP11C (ATPase phospholipid transporting 11C).
