Predicted to enable aminophospholipid flippase activity. Predicted to be involved in several processes, including phospholipid transport; positive regulation of cellular component organization; and xenobiotic transmembrane transport. Predicted to be located in several cellular components, including apical plasma membrane; photoreceptor inner segment; and photoreceptor outer segment. Predicted to be integral component of membrane. Predicted to be part of phospholipid-translocating ATPase complex. Predicted to be active in Golgi apparatus; endoplasmic reticulum; and plasma membrane. Orthologous to human TMEM30A (transmembrane protein 30A). [provided by Alliance of Genome Resources, Apr 2022]
