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 [Source:SGD;Acc:S000005537]

Chromosome XV: 349,679-353,863 forward strand.

R64-1-1:BK006948.2

This gene has 1 transcript (splice variant), 549 orthologues and 9 paralogues.
