用于直接干扰蛋白质稳态的化学生物学策略,包括降解标签(dTAG)系统,提供了优于遗传方法的时间优势和优于小分子抑制剂的改进的选择性。我们描述了dTAGV-1,一种专门选择性的VHL募集dTAG分子,可快速降解FKBP 12 F36 V标记的蛋白质。dTAGV-1克服了以前报道的CRBN募集dTAG分子降解致癌基因的局限性,支持组合降解剂研究,并促进细胞和小鼠中蛋白质功能的研究。dTAG系统用于在体外和体内快速耗尽标记的靶蛋白,但其有效性存在背景和蛋白质特异性差异。在这里,作者开发了第二代dTAG分子,可以降解细胞和小鼠中以前顽固的靶蛋白。
Chemical biology strategies for directly perturbing protein homeostasis including the degradation tag (dTAG) system provide temporal advantages over genetic approaches and improved selectivity over small molecule inhibitors. We describe dTAGV-1, an exclusively selective VHL-recruiting dTAG molecule, to rapidly degrade FKBP12F36V-tagged proteins. dTAGV-1 overcomes a limitation of previously reported CRBN-recruiting dTAG molecules to degrade recalcitrant oncogenes, supports combination degrader studies and facilitates investigations of protein function in cells and mice. The dTAG system is used to rapidly deplete tagged target proteins in vitro and in vivo, but there are context- and protein-specific differences in its effectiveness. Here, the authors develop a second generation dTAG molecule that can degrade previously recalcitrant target proteins in cells and mice.
