• • Common Types and Functional Analysis of Post-Translational Modifications

  Proteins are essential executors of biological functions. Most functional proteins must undergo a series of chemical modifications after translation—collectively known as post-translational modifications (PTMs)—to enable precise regulation of their three-dimensional structure, subcellular localization, and functional state. These modifications not only enhance the structural and functional diversity of proteins but also play indispensable roles in critical biological processes, including signal .......

• • Comprehensive Overview of Common Techniques and Application Scenarios in Post-translational Modifications (PTMs) Research

  In the context of cellular life processes, proteins often do not attain full functionality immediately after synthesis. Many require post-translational modifications (PTMs) to regulate their structural stability, subcellular localization, molecular interactions, and biological activity. PTMs have emerged as a critical area in modern life sciences, with broad applications in elucidating disease mechanisms, validating drug targets, and discovering biomarkers. Research Challenges in Post-translational ........

• • Applications and Advantages of Mass Spectrometry in Single Cell Proteomics

  Life sciences research is increasingly focusing on the single-cell level, with single-cell proteomics (SCP) emerging as a critical approach for elucidating cellular heterogeneity and dissecting complex biological processes. Although single-cell transcriptomics is widely applied, the lack of consistent correlation between mRNA abundance and protein expression underscores the importance of direct protein-level measurements for accurately capturing cellular functional states. Mass spectrometry (MS), as a .....
