This report describes the localization of Fic1 in rat liver and intestine, as well as biochemical and transfection studies that support its function as an energy-dependent aminophospholipid translocase.
In canalicular membrane vesicles, translocase activity had an initial velocity of 3.3 nmol phosphatidylserine (PS) translocated per milligram of protein per minute and a K (m) (ATP) = 1.2 mmol/L; was inhibited by vanadate, N-ethylmaleimide, sodium azide, and calcium; and was unidirectional (i.e., from the outer to the inner canalicular plasma membrane leaflet).

This "flip" process, which occurred at 20 degrees C, was abolished when the endothelial cells were preincubated with N-ethylmaleimide, diamide, vanadate (VO4 (3-)) and vanadyl (VO2+) ions, a set of substances which inhibit aminophospholipid translocase activity in various systems, and with a combination of sodium azide and 2-deoxyglucose which led to nearly complete ATP depletion in the cells.
