Protein Structure

UniProt Annotation

Function

Catalytic component of a P4-ATPase flippase complex which catalyzes the hydrolysis of ATP coupled to the transport of aminophospholipids from the outer to the inner leaflet of various membranes and ensures the maintenance of asymmetric distribution of phospholipids. Phospholipid translocation seems also to be implicated in vesicle formation and in uptake of lipid signaling molecules (Probable). May be involved in the uptake of farnesyltransferase inhibitor drugs, such as lonafarnib. {ECO:0000269PubMed:15860663, ECO:0000305}.

Subcellular Localization

Cell membrane {ECO:0000269PubMed:21914794}; Multi-pass membrane protein {ECO:0000269PubMed:21914794}. Early endosome {ECO:0000269PubMed:21914794}. Recycling endosome {ECO:0000269PubMed:21914794}. Endoplasmic reticulum {ECO:0000269PubMed:21914794}. Note=Exit from the endoplasmic reticulum requires the presence of TMEM30A, but not TMEM30B. In the presence of TMEM30A, predominantly located in the plasma membrane.
