Protein Information (annotations from UniProt)

Database IDHIV0000196
UniProt IDQ9Y2Q0
Primary gene name(s)ATP8A1
Synonym gene name(s)ATPIA
Protein namePhospholipid-transporting ATPase IA
Protein functionCatalytic 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. In vitro, its ATPase activity is selectively and stereospecifically stimulated by phosphatidylserine, PS. The flippase complex ATP8A1:TMEM30A seems to play a role in regulation of cell migration probably involving flippase-mediated translocation of phosphatidylethanolamine, PE at the plasma membrane. Acts as aminophospholipid translocase at the plasma membrane in neuronal cells.

Note=Exit from the endoplasmic reticulum requires the presence of TMEM30A, but not TMEM30B, PubMed:20947505. In the presence of TMEM30A, predominantly located in cytoplasmic punctate structures and localizes to the plasma membrane, PubMed:20947505. Localizes to plasma membranes of red blood cells, By similarity. {ECO:0000250|UniProtKB:P70704, ECO:0000269|PubMed:20947505}.
