Endocytosis and vacuolar degradation of the plasma membrane-localized Pdr5 ATP-binding cassette multidrug transporter in Saccharomyces cerevisiae.
Multidrug resistance (MDR) to different cytotoxic compounds in the yeast Saccharomyces cerevisiae can arise from overexpression of the Pdr5 (Sts1, Ydr1, or Lem1) ATP-binding cassette (ABC) multidrug transporter. We have raised polyclonal antibodies recognizing the yeast Pdr5 ABC transporter to study its biogenesis and to analyze the molecular mechanisms underlying MDR development. Subcellular f...
متن کاملRequirement of the N-terminal extension for vacuolar trafficking and transport activity of yeast Ycf1p, an ATP-binding cassette transporter.
Ycf1p is the prototypical member of the yeast multidrug resistance-associated protein (MRP) subfamily of ATP-binding cassette (ABC) transporters. Ycf1p resides in the vacuolar membrane and mediates glutathione-dependent transport processes that result in resistance to cadmium and other xenobiotics. A feature common to many MRP proteins that distinguishes them from other ABC transporters is the ...
متن کاملThe PAL1 gene product is a peroxisomal ATP-binding cassette transporter in the yeast Saccharomyces cerevisiae
The PAL1 gene was isolated using PCR and degenerate oligonucleotide primers corresponding to highly conserved amino acid sequence motifs diagnostic of the ATP-binding cassette domain of the superfamily of membrane-bound transport proteins typified by mammalian multidrug resistance transporter 1 and Saccharomyces cerevisiae Ste6. The deduced PAL1 gene product is similar in length to, has the sam...
متن کاملThe role of ATP-binding cassette transporter A2 in childhood acute lymphoblastic leukemia multidrug resistance
Acute lymphoblastic leukemia (ALL) is one of the most prevalent hematologic malignancies in children. Although the cure rate of ALL has improved over the past decades, the most important reason for ALL treatment failure is multidrug resistance (MDR) phenomenon. The current study aims to explain the mechanisms involved in multidrug resistance of childhood ALL, and introduces ATP-binding cassette...
متن کاملInvolvement of Saccharomyces cerevisiae Pdr5p ATP-binding cassette transporter in calcium homeostasis.
Deletion of PDR5 gene (Deltapdr5) in Saccharomyces cerevisiae led to increased resistance to calcium. The cellular Ca2+ level in the presence of high calcium as estimated by reporter assay in Deltapdr5 cells was significantly lower than that in wild-type cells. Membrane Pdr5p levels diminished rapidly during incubation with high calcium in a manner dependent on calcineurin and Pep4p, suggesting...
