Abstract

The yeast transcription factors Pdr1 and Pdr3 control pleiotropic drug resistance (PDR) development, since they regulate expression of ATP‐binding cassette (ABC) drug efflux pumps through binding to cis‐acting sites known as PDREs ( R esponsive lements). In this report, we show by Northern blotting, gel shift mobility assays and DNase I footprinting that transcription of the ABC genes PDR10 and PDR15 is also controlled by Pdr1 and Pdr3. In addition, in vitro band shift assays demonstrate that a GST‐Pdr1 fusion protein can bind to the PDREs of PDR10 and PDR15. DNase I footprinting allowed the identification of the precise PDRE binding motifs, indicating the presence of a novel slightly degenerate PDRE motif in the PDR15 promoter. Finally, PDR10 and PDR15 mRNA levels vary dramatically in abundance in isogenic yeast strains carrying either Δ pdr1, Δ pdr3 and Δ pdr1 Δ pdr3 deletions or pdr1‐3 and pdr3‐2 gain‐of‐function mutations, demonstrating that both PDR10 and PDR15 are new members of the yeast PDR network.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
