This domain is found at the C-terminal end of human Phospholipid -transporting ATPase ABCA1 and similar sequences predominantly found in animals. ABCA1 catalyses the translocation of specific phospholipids from the cytoplasmic to the extracellular/lumenal leaflet of membrane coupled to the hydrolysis of ATP. This entry represents the regulatory domain R2 which shows a beta-sheet and two alpha-helices on one side [1,4].	Domain
