Protein: Phospholipid-transporting ATPase VA (EC 7.6.2.1) (ATPase class V type 10A) (Aminophospholipid translocase VA) (P4-ATPase flippase complex alpha subunit ATP10A) (O60312)
Organism: Homo sapiens (Human)
Function: Catalytic component of P4-ATPase flippase complex, which catalyzes the hydrolysis of ATP coupled to the transport of phosphatidylcholine (PC) from the outer to the inner leaflet of the plasma membrane. Initiates inward plasma membrane bending and recruitment of Bin/amphiphysin/Rvs (BAR) domain-containing proteins involved in membrane tubulation and cell trafficking. Facilitates ITGB1/beta1 integrin endocytosis, delaying cell adhesion and cell spreading on extracellular matrix. Has low flippase activity toward glucosylceramide (GlcCer).
Subcellular location: Cell membrane {ECO:0000269|PubMed:21914794, ECO:0000269|PubMed:25947375, ECO:0000269|PubMed:30530492}; Multi-pass membrane protein {ECO:0000269|PubMed:21914794}. Endoplasmic reticulum membrane {ECO:0000269|PubMed:21914794, ECO:0000269|PubMed:25947375}. Note=Exit from the endoplasmic reticulum requires the presence of TMEM30A, but not that of TMEM30B.
