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). Involved in regulation of sensitivity to cisplatin; may contribute to secretory vesicle transport of cisplatin from Golgi to plasma membrane. {ECO:0000269PubMed:23585472, ECO:0000305}.

Subcellular Localization

Recycling endosome membrane; Multi-pass membrane protein. Early endosome. Endoplasmic reticulum. Golgi apparatus, trans-Golgi network. Note=Exit from the endoplasmic reticulum requires the presence of TMEM30A, but not TMEM30B. In the presence of TMEM30A, mainly located in recycling endosomes.
