中文摘要:
      蛋白质的C末端在蛋白质进行各项生命活动过程中都起着极其重要的作用。它不仅标志着DNA转录翻译成蛋白质过程的初步完成,更是参与和调控了蛋白质的各种生理功能。研究蛋白质的C末端不仅有利于完整蛋白质的鉴定,对于在分子水平理解蛋白质的信号传导和生化功能是十分必要的。文中结合我们的研究工作,综述了近年来基于生物质谱的蛋白质C末端研究的相关进展,包括了C末端的识别、鉴定以及蛋白质C末端肽段富集的新方法和新技术。
英文摘要:
      C-termini of proteins often play an important role in various biological processes, such as the transcription and translation from DNA to protein and also participating in various biological regulations. The determination of protein C-terminus is so crucial because it provides not only distinct functional annotation, but also a way to monitor the proteolysis-modified proteins. Based on the biological mass spectrometry, a series of novel methods and technologies were developed both for qualitative and quantitative analyses of protein C-terminus. These methods or technologies can be applied to accurate and effective protein C-terminus profiling, including the sequences and quantitative information of C-termini, which reveals the biological function of C-termini in life’s activities and provides a better understanding of the degradation of mature proteins. Combined with our research, this review highlights the improvements in C-terminal proteomics study in the past decades, including the methodologies for recognition and identification of C-terminus, as well as the enrichment strategies for protein C-terminus.
