Reports
A Subfamily of P-Type ATPases with Aminophospholipid Transporting
Activity
Xiaojing Tang,

A. Schlegel,

*
The appearance of phosphatidylserine on the surface of animal cells
triggers phagocytosis and blood coagulation. Normally,
phosphatidylserine is confined to the inner leaflet of the plasma
membrane by an aminophospholipid translocase, which has now been cloned
and sequenced. The bovine enzyme is a member of a previously
unrecognized subfamily of P-type adenosine triphosphatases (ATPases)
that may have diverged from the primordial enzyme before the separation
of the known families of ion-translocating ATPases. Studies in
Saccharomyces cerevisiae suggest that aminophospholipid
translocation is a general function of members of this family.
