Despite a billion years of divergent evolution, the baker's yeast Saccharomyces cerevisiae has long proven to be an invaluable model organism for studying human biology. Given its tractability and ease of genetic manipulation, along with extensive genetic conservation with humans, it is perhaps no surprise that researchers have been able to expand its utility by expressing human proteins in yeast, or by humanizing specific yeast amino acids, proteins or even entire pathways. These methods are increasingly being scaled in throughput, further enabling the detailed investigation of human biology and disease-specific variations of human genes in a simplified model organism.
尽管经历了十亿年的分化进化,但长期以来,面包酵母酿酒酵母已被证明是研究人类生物学的一种极其宝贵的模式生物。鉴于其易于处理和便于进行基因操作,以及与人类广泛的基因保守性,研究人员能够通过在酵母中表达人类蛋白质,或对特定的酵母氨基酸、蛋白质甚至整个途径进行人源化改造来扩展其用途,这或许并不令人惊讶。这些方法的通量越来越高,进一步使得在一个简化的模式生物中对人类生物学以及人类基因的疾病特异性变异进行详细研究成为可能。
