    Abstract: A system allows for rapid and specific induction of individual genes in eukaryotic cells using a chimeric transcriptional activator that is responsive to hormone inducer. Upon addition of the hormone, cytoplasmic transcriptional activator localizes to the nucleus and subsequently binds to promoters containing sequences that bind to its DNA-binding domain. Genetic modifications allow for rapid and specific degradation of a targeted protein upon addition of hormone by means of a regulated degron method that utilizes a protease variant. This system is useful for discovering new compounds by high throughput screening when introducing compound libraries to these protein-depleted cells.

    Abstract translation: 一种系统允许使用对激素诱导剂有反应的嵌合转录激活物来快速和特异性地诱导真核细胞中的单个基因。 加入激素后,细胞质转录激活剂定位于细胞核,随后与含有结合其DNA结合域的序列的启动子结合。 遗传修饰允许通过利用蛋白酶变体的经调节的degron方法加入激素时靶向蛋白质的快速和特异性降解。 当将这些蛋白质耗尽的细胞引入化合物文库时,该系统可用于通过高通量筛选发现新的化合物。
