Pry1 mediates the export of acetylated sterols, such as cholesteryl acetate, from yeast cells. Key findings include:
Pry1 confers resistance to toxic hydrophobic agents like eugenol:
Deletion of PRY1 causes hypersensitivity to eugenol, reversed by human CRISP2 expression .
Competitive binding assays show Pry1 directly sequesters eugenol, protecting cellular membranes .
While the provided sources focus on Pry1’s biological roles, inferred applications of pry-1 antibodies include:
Western Blotting: Detecting Pry1 expression in yeast lysates or secreted fractions .
Immunoprecipitation: Isolating Pry1-protein or Pry1-lipid complexes for functional studies .
Localization Studies: Tracking Pry1 secretion and membrane association via immunofluorescence .
Pry1 shares functional homology with other CAP-domain proteins:
| Protein | Organism | Function | Key Similarity |
|---|---|---|---|
| Pry1 | S. cerevisiae | Sterol export, detoxification | CAP domain-mediated lipid binding |
| UmPR-1La | Ustilago maydis | Fungal virulence, plant defense evasion | Structural CAP domain conservation |
| Human CRISP2 | Homo sapiens | Sperm maturation, ion channel regulation | Detoxification rescue capability |
