作者（2019）在《Recent advances in the chemical synthesis and semi-synthesis of poly-ubiquitin-based proteins and probes》一文中研究指出：Ubiquitination, a key and extensive posttranslational modification of proteins, has profound effects on a variety of physiological and pathological processes. The inherent complexity of ubiquitin conjugates makes it highly challenging to study the functional and structural mechanisms of ubiquitination. To address these challenges, accesses to sufficient poly-ubiquitin chains or ubiquitinated proteins are urgently needed. Over the last decade, synthetic protein chemists have developed several novel peptide ligation methods for the preparation of ubiquitin conjugates with precise control over the atomic structure. In this review, we summarize the recent breakthroughs and potential challenges in the chemical synthesis and semi-synthesis of ubiquitin conjugates with respect to the preparation of poly-ubiquitin-based proteins and ubiquitin-based probes.
Abstract
Ubiquitination, a key and extensive posttranslational modification of proteins, has profound effects on a variety of physiological and pathological processes. The inherent complexity of ubiquitin conjugates makes it highly challenging to study the functional and structural mechanisms of ubiquitination. To address these challenges, accesses to sufficient poly-ubiquitin chains or ubiquitinated proteins are urgently needed. Over the last decade, synthetic protein chemists have developed several novel peptide ligation methods for the preparation of ubiquitin conjugates with precise control over the atomic structure. In this review, we summarize the recent breakthroughs and potential challenges in the chemical synthesis and semi-synthesis of ubiquitin conjugates with respect to the preparation of poly-ubiquitin-based proteins and ubiquitin-based probes.
