DESCRIPTION (provided by applicant): A formidable toolkit exists for manipulating protein expression at the transcriptional level, but the methods for the post-translational modulation of proteins are few and of limited utility. A small molecule that induces degradation of endogenous proteins would clearly be a tremendously useful tool for probing protein function and an exciting approach for chemotherapy. The challenge is to develop technology that is biocompatible and widely applicable. We have serendipitously discovered a moiety that when combined with a recognition element, induces degradation of the target protein. We propose to characterize this phenomenon and develop these novel tools for protein knockdown that will be invaluable in a broad array of biological and pharmaceutical applications.

描述(由申请人提供)：有一个强大的工具包可以在转录水平上操纵蛋白质的表达，但用于蛋白质翻译后调节的方法很少，而且实用有限。诱导内源性蛋白质降解的小分子显然是探索蛋白质功能的一个非常有用的工具，也是一种令人兴奋的化疗方法。挑战是开发生物兼容和广泛适用的技术。我们偶然发现了一种部分，当与识别元件结合时，会导致目标蛋白的降解。我们建议描述这一现象，并开发这些新的蛋白质敲除工具，这将在广泛的生物和制药应用中具有无价的价值。
