AUS1 [YOR011W]
ATP-dependent permease AUS1; Plasma membrane sterol transporter of the ATP-binding cassette family; required, along with Pdr11p, for uptake of exogenous sterols and their incorporation into the plasma membrane; activity is stimulated by phosphatidylserine; sterol uptake is required for anaerobic growth because sterol biosynthesis requires oxygen; AUS1 has a paralog, PDR11, that arose from the whole genome duplication
Synonyms: AUS1, AUS1p, E9PA01, E9PA77, Q08409 ...
