Transcriptional regulation in response to environmental challenges is crucial for survival of many organisms. In this study, we characterized structural and functional properties of CgAP1, a Saccharomyces cerevisiae YAP1 ortholog, which encodes a transcription factor involved in various stress responses. Deletion of CgAP1 led to decreased resistance to hydrogen peroxide, 4-nitroquinoline-N-oxide (4-NQO),...
The understanding and analysis of protein associations in living cells is a major goal of molecular biology. Here, we describe an assay for the analysis of protein–protein interactions based on the co-localization of a fused site-specific protease with a cleavable reporter in close proximity to the interaction partner under examination. We exemplified this scheme in the temperature-sensitive Saccharomyces...
Elucidating novel anti-apoptotic regulatory pathways is central to further understanding the molecular basis of several pathologies, including cancer. We have previously reported the identification of several mammalian cDNAs effective in preventing the lethal effects of heterologous expression of a pro-apoptotic BAX cDNA in yeast [Yang, Z., Khoury, C., Jean-Baptiste, G., Greenwood, M.T., 2006. Identification...
Yeasts are attractive organisms for recombinant protein production. They combine highly developed genetic systems and ease of use with reductions in time and costs. We describe an autoselection system for recombinant protein expression in Saccharomyces cerevisiae which increases yields 5–10-fold compared to conditional selection for expression plasmids. Multicopy expression plasmids encoding essential...
