ATPase, aminophospholipid transporter (APLT), class I, type 8A, member 1 is a human gene encoded by the symbol, ATP8A1. It may also be known as: Phospholipid-transporting ATPase IA; ATPase class I type 8A member 1; Chromaffin granule ATPase II; P4-ATPase flippase complex alpha subunit ATP8A1; Phospholipid-transporting ATPase IA ; ATPASEII; ATPIA; ATPP2. The encoded protein is an enzyme with an amino acid length of 1164 and a mass of 131.4 kDa. Other isoforms may exist. ATPase, aminophospholipid transporter (APLT), class I, type 8A, member 1 is a member of the Cation transport ATPase (P-type) (TC 3.A.3) family, Type IV subfamily. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
