  • Title: Posttranslational modifications in systems biology.
    Author: Aggarwal S, Tolani P, Gupta S, Yadav AK.
    Journal: Adv Protein Chem Struct Biol; 2021; 127():93-126. PubMed ID: 34340775.
    Abstract:
    The biological complexity cannot be captured by genes or proteins alone. The protein posttranslational modifications (PTMs) impart functional diversity to the proteome and regulate protein structure, activity, localization and interactions. Their dynamics drive cellular signaling, growth and development while their dysregulation causes many diseases. Mass spectrometry based quantitative profiling of PTMs and bioinformatics analysis tools allow systems level insights into their network architecture. High-resolution profiling of PTM networks will advance disease understanding and precision medicine. It can accelerate the discovery of biomarkers and drug targets. This requires better tools for unbiased, high-throughput and accurate PTM identification, site localization and automated annotation on a systems level.
