热休克蛋白90(Heat-shock protein 90,Hsp 90)是细胞蛋白质稳态的重要调节因子。它稳定了许多参与生命基本过程的蛋白质,包括细胞生长,细胞周期进程和环境反应。除了稳定蛋白质外,Hsp 90还控制基因表达和控制隐藏遗传变异的释放。鉴于其在进化和发育中的核心作用,鉴定与Hsp 90相互作用的蛋白质和基因非常重要。这需要复杂的遗传和生化工具,包括广泛的突变体收集,合适的表位标签,蛋白质组学方法和Hsp 90特异性药理学抑制剂的化学基因组学筛选。这些通常只存在于模式生物中,如酿酒酵母。然而,其他真菌物种的重要性,如白色念珠菌和新型隐球菌,作为严重的人类病原体加速了遗传工具的发展,以研究其毒力和应激反应途径。这些工具也可以用来绘制Hsp 90相互作用网络。在这里,我们审查的工具和技术,热休克蛋白90网络映射可在不同的真菌,并提供了现有的映射工作的总结。在跨越5亿年进化的真菌物种中绘制Hsp 90网络提供了一个独特的Vantage位置,允许跟踪真核Hsp 90网络的进化历史。真菌中的Hsp 90网络为研究网络进化提供了一个独特的机会。
Heat-shock protein 90 (Hsp90) is a central regulator of cellular proteostasis. It stabilizes numerous proteins that are involved in fundamental processes of life, including cell growth, cell-cycle progression and the environmental response. In addition to stabilizing proteins, Hsp90 governs gene expression and controls the release of cryptic genetic variation. Given its central role in evolution and development, it is important to identify proteins and genes that interact with Hsp90. This requires sophisticated genetic and biochemical tools, including extensive mutant collections, suitable epitope tags, proteomics approaches and Hsp90-specific pharmacological inhibitors for chemogenomic screens. These usually only exist in model organisms, such as the yeast Saccharomyces cerevisiae. Yet, the importance of other fungal species, such as Candida albicans and Cryptococcus neoformans, as serious human pathogens accelerated the development of genetic tools to study their virulence and stress response pathways. These tools can also be exploited to map Hsp90 interaction networks. Here, we review tools and techniques for Hsp90 network mapping available in different fungi and provide a summary of existing mapping efforts. Mapping Hsp90 networks in fungal species spanning >500 million years of evolution provides a unique vantage point, allowing tracking of the evolutionary history of eukaryotic Hsp90 networks. Hsp90 networks in fungi provide a unique opportunity for the study of network evolution.
