ATOX1 is a copper chaperone involved in intracellular copper homeostasis, cell proliferation, and tumor progression. To investigate the physiologically relevant molecular mechanism of ATOX1 by using imaging-based approaches, we genetically modified ATOX1 in H1 hESCs to express mCherry-ATOX1 fusion protein under endogenous regulatory machinery. The fluorescence engineered hESC clone maintains characteristic stem cell features and can differentiate to all three germ layers, serving as a unique tool to dissect the role of ATOX1 in various cellular processes.
ATOX1是一种参与细胞内铜稳态、细胞增殖和肿瘤进展的铜伴侣蛋白。为了通过基于成像的方法研究ATOX1的生理相关分子机制，我们在H1人胚胎干细胞中对ATOX1进行基因改造，使其在内源调控机制下表达mCherry-ATOX1融合蛋白。荧光工程化的人胚胎干细胞克隆保持了特征性的干细胞特性，并且可以分化为所有三个胚层，是剖析ATOX1在各种细胞过程中作用的独特工具。
