Proteins belonging to the CAP superfamily are present in all kingdoms of life and have been implicated in different physiological processes. Their molecular mode of action, however, is poorly understood. Saccharomyces cerevisiae expresses three members of this superfamily, pathogen-related yeast (Pry)1, -2, and -3. We have recently shown that Pry function is required for the secretion of...

Saccharomyces cerevisiae, a model to study sterol uptake and transport in eukaryotes

Reiner, Sonja ; Micolod, Delphine ; Schneiter, Roger

In: Biochemical Society Transactions, 2005, vol. 33, no. 5, p. 1186-1188

The molecular mechanisms that govern intracellular transport of sterols in eukaryotic cells are only poorly understood. Saccharomyces cerevisiae is a facultative anaerobic organism that requires supplementation with unsaturated fatty acids and sterols to grow in the absence of oxygen, as the synthesis of these lipids requires molecular oxygen. The fact that yeast grows well under anaerobic...
