What is the function of this protein?
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 (PubMed:20224745, PubMed:16618126).  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) (PubMed:20224745, PubMed:16618126).  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 (PubMed:23269685).  Acts as aminophospholipid translocase at the plasma membrane in neuronal cells; the activity is associated with hippocampus-dependent learning (PubMed:22007859).  May play a role in brain connectivity (PubMed:27287255).
What are the official names of this protein?
Phospholipid-transporting ATPase IA, ATPase class I type 8A member 1, Chromaffin granule ATPase II, P4-ATPase flippase complex alpha subunit ATP8A1.
What is the protein family that this protein belongs to?
Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IV subfamily.
What are the subcellular locations of this protein?
Cytoplasmic vesicle, secretory vesicle, chromaffin granule membrane; Multi-pass membrane protein. Cytoplasmic granule. Cell membrane. Endoplasmic reticulum. Golgi apparatus. Cytoplasmic vesicle. Endomembrane system. Note=Exit from the endoplasmic reticulum requires the presence of TMEM30A, but not TMEM30B. In the presence of TMEM30A, predominantly located in cytoplasmic punctate structures (By similarity). Localizes to plasma membranes of red blood cells (PubMed:16643453). Localizes predominantly in the intracellular membranes, rather than the plasma membrane of platelets (PubMed:30674456).
