Disease relevance of PDR5


High impact information on PDR5

  • Furthermore, YDR1 overexpression impaired cell growth, an effect that could be rescued by overexpression of TBP [4].
  • The repressor complex is encoded by two essential genes, designated YDR1 and BUR6 [4].
  • We isolated a yeast mutant, lem1, with increased sensitivity to dexamethasone and triamcinolone acetonide; responsiveness to a third agonist, deoxycorticosterone, is unaffected [5].
  • We propose that transporters like LEM1 can selectively modulate the intracellular levels of steroid hormones [5].
  • Genetic analysis of the YDR1-BUR6 repressor complex reveals an intricate balance among transcriptional regulatory proteins in yeast [6].

Chemical compound and disease context of PDR5


Biological context of PDR5

  • Overexpression of Pdr13p leads to an increase in both the expression of PDR5 and YOR1 and a corresponding enhancement in drug resistance [12].
  • The yeast PDR5 gene encodes an efflux pump that confers multidrug resistance [13].
  • Loss of previously described nuclear-mitochondrial signaling genes like RTG1 reduce the level of PDR5 expression and drug resistance seen in rho(o) cells but has no effect on oxa1-induced phenotypes [14].
  • Disruption of both PDR5 and SNQ2 in a pdr1 mutant decreases the cell growth rate and reveals the presence of at least two other ATP binding cassette proteins in the 160-kDa overexpressed band that have been identified by amino-terminal microsequencing [15].
  • We have carried out a genetic screen to identify negative regulators of PDR5 expression and found that loss of the mitochondrial genome (rho(o) cells) causes up-regulation of Pdr3p but not Pdr1p function [14].

Anatomical context of PDR5


Associations of PDR5 with chemical compounds

  • The ATP binding cassette transporter-encoding genes regulated by Pdrlp include PDR5 and YOR1, which are required for normal cycloheximide and oligomycin tolerances, respectively [12].
  • The enzyme shows a nucleoside triphosphatase activity that differs biochemically from that of PDR5 (Decottignies, A., Kolaczkowski, M., Balzi, E., and Goffeau, A. (1994) J. Biol. Chem. 269, 12797-12803) and is sensitive to vanadate, erythrosine B, and Triton X-100 but not to oligomycin, which inhibits the PDR5 activity only [15].
  • Library deconvolution identified the 4-methoxy-2,3,6-trimethylbenzensulfonyl-substituted D-octapeptide KN20 as a potent Pdr5p ATPase inhibitor (concentration of drug causing 50% inhibition of enzyme activity [IC(50)], 4 microM) which chemosensitized AD/PDR5(+) to FLC, itraconazole, and ketoconazole [20].
  • Here, we show that PDR5 promoter activity is dramatically reduced when cells stop growing due to a limitation of glucose or nitrogen or when they approach stationary phase [21].
  • Although the protective role of TPO1 and PDR5 genes was confirmed, the majority of the responsive genes encoding multidrug resistance do not confer resistance to 2,4-D [22].

Physical interactions of PDR5

  • Loss of the mitochondrial genome (rho(0) cell) or elimination of the mitochondrial inner membrane protein Oxa1p causes a dramatic increase in expression of the ATP binding cassette transporter-encoding gene PDR5 in the yeast Saccharomyces cerevisiae [23].
  • Overexpression of the yeast Pdr5 ATP-binding cassette transporter leads to pleiotropic drug resistance to a variety of structurally unrelated cytotoxic compounds [24].
  • Interestingly, yeast Pdr5p interacted with flavonoids recently found to bind to cancer cell P-glycoprotein and to the protozoan parasite multidrug transporter [25].

Regulatory relationships of PDR5

  • However, the camptothecin resistance accompanying GAL1-promoted overexpression of PDR5 suggests some substrate promiscuity among the ATP-binding cassette transporters [26].
  • FDR-1 has been found to be an activated allele of the Pleiotropic Drug Resistance-1 (PDR-1) gene (termed PDR1-100) and to upregulate PDR5 transcription [17].
  • Pdr3p is involved in a retrograde response in which mitochondrial dysfunctions activate PDR5, a gene encoding an ABC membrane transporter [27].
  • A PDR5-independent pathway of multi-drug resistance regulated by the SIN4 gene product [28].

Other interactions of PDR5

  • Transcriptional control of the yeast PDR5 gene by the PDR3 gene product [29].
  • The PDR1 T879M mutant increased PDR5 transcription compared with wild-type PDR1 strains [26].
  • The ATP binding cassette transporters Pdr5 and Snq2 of Saccharomyces cerevisiae can mediate transport of steroids in vivo [1].
  • We also analyzed the interaction between PDR5 and YAP1 [30].
  • Zinc cluster protein Rdr1p is a transcriptional repressor of the PDR5 gene encoding a multidrug transporter [13].
