In the last two decades, targeted protein degradation has rapidly gained popularity as a technique to eliminate disease-causing undruggable proteins. Over the years, many tools have been devised to degrade proteins by exploiting natural protein homeostasis machinery available in our body, with LYTACs being the latest to come on board. LYTACs, or lysosome-targeting chimeras, make use of the lysosome degradation pathway by recruiting proteins to lysosome-shuttling receptors located at the cell surface. LYTACs are specifically meant for the degradation of membrane-bound and extracellular proteins, which account for the products of 40 % of all protein-encoding genes. In this highlight, we describe two studies that demonstrate the scope of LYTACs and its advantages over the other protein degradation platforms. In the first study, the LYTAC utilizes the cation-independent mannose-6-phosphate receptor (CI-M6PR), while the second study uses the asialoglycoprotein receptor (ASGPR) which is found only on the surface of liver cells.
在过去的二十年中,靶向蛋白降解作为一种消除难以治疗的致病蛋白的技术迅速流行起来。多年来,人们设计了许多工具来利用我们体内天然的蛋白质内稳态机制来降解蛋白质,其中 LYTACs 是最新的一种。LYTACs,或溶酶体靶向嵌合体,通过招募蛋白质到位于细胞表面的溶酶体穿梭受体,利用溶酶体降解途径。LYTACs 专门用于降解膜结合蛋白和细胞外蛋白,这些蛋白占所有编码蛋白质基因的产物的 40%。在这篇重点介绍中,我们描述了两项研究,展示了 LYTACs 的范围及其相对于其他蛋白质降解平台的优势。在第一项研究中,LYTAC 利用阳离子非依赖性甘露糖-6-磷酸受体(CI-M6PR),而第二项研究使用仅存在于肝细胞表面的去唾液酸糖蛋白受体(ASGPR)。
