摘要综述了光亲和标记技术在生物大分子相互作用研究中的应用。PAL是一种很有前途的分析配体与受体相互作用的技术。结合可释放化学交联剂和PAL是一个跨学科的研究方向。结合可释放化学交联剂和光亲和探针是鉴定蛋白质-蛋白质相互作用(PPI)的有价值的工具。使用可释放的光亲和连接物制备的生物大分子光亲和探针可用于通过触发可释放基团的释放来探索PPI。更重要的是,它可以克服没有标记转移功能的大分子光亲和探针的缺点,准确地确定特定结构位点的缺陷。它在探索未知蛋白质与活体中瞬时弱PPI相互作用以发现新的药物靶点方面显示出特别的前景。在这篇综述中,我们重点介绍了化学可释放连接物在光亲和探针中的开发和应用的最新进展。描述了几个比较研究,其中比较了各种光亲和探针的效率。
HighlightsIt presents an overview of photoaffinity label in exploring interaction of biomacro-molecules.PAL is a promising technique in analyzing the interaction between ligand and receptor.Combining releasable chemical crosslinking and PAL is an interdisciplinary proposal.Combining releasable chemical crosslinkers with photoaffinity probes represents a valuable tool for identifying protein–protein interactions (PPIs). The biomacromolecule photoaffinity probe prepared by using releasable photoaffinity linkers can be used to exploring PPIs by triggering release of the releasable group. More importantly, it can overcome the shortcomings of macromolecular photoaffinity probes without label transfer functionality to accurately confirm defects in specific structural sites. It shows particular promise for research exploring the interaction of unknown proteins and transient–weak PPIs in living organisms to discover new drug targets. In this review, we highlight recent progress in the development and application of chemical releasable linkers in photoaffinity probes. Several comparative studies are described in which the efficiency of various photoaffinity probes are compared.
