布氏锥虫是一种模式锥虫,是人类、动物和植物的重要单细胞寄生虫。了解它们复杂的细胞结构和生命周期具有挑战性,因为与大多数真核微生物一样,约50%的基因组编码蛋白质具有完全未知的功能。在这里,使用荧光显微镜和表达内源性标记蛋白的细胞系,我们绘制了89%的布氏锥虫蛋白质组的亚细胞定位,我们称之为TrypTag。我们提供了线索的功能和定义谱系特异性的细胞器适应寄生,绘制真核生物的ultraconserved细胞结构,包括第一次全面的“制图”分析真核生物鞭毛,这是至关重要的形态发生和病理。为了证明这种资源的力量,我们确定了新的细胞器子域和分子组成的变化,通过细胞周期。TrypTag是一种变革性资源,对于真核进化分子细胞生物学和基础寄生虫细胞生物学的假设生成非常重要。89%的布氏锥虫蛋白质组是使用荧光显微镜和表达内源性标记蛋白质的细胞系绘制的,并在名为TrypTag.org的社区资源中呈现。
Trypanosoma brucei is a model trypanosomatid, an important group of human, animal and plant unicellular parasites. Understanding their complex cell architecture and life cycle is challenging because, as with most eukaryotic microbes, ~50% of genome-encoded proteins have completely unknown functions. Here, using fluorescence microscopy and cell lines expressing endogenously tagged proteins, we mapped the subcellular localization of 89% of the T. brucei proteome, a resource we call TrypTag. We provide clues to function and define lineage-specific organelle adaptations for parasitism, mapping the ultraconserved cellular architecture of eukaryotes, including the first comprehensive ‘cartographic’ analysis of the eukaryotic flagellum, which is vital for morphogenesis and pathology. To demonstrate the power of this resource, we identify novel organelle subdomains and changes in molecular composition through the cell cycle. TrypTag is a transformative resource, important for hypothesis generation for both eukaryotic evolutionary molecular cell biology and fundamental parasite cell biology. Eighty-nine percent of the Trypanosoma brucei proteome is mapped using fluorescence microscopy and cell lines expressing endogenously tagged proteins, and presented in a resource for the community named TrypTag.org.
