Glycoproteomics

Thanks to advancements in instrumentation, experimental methodologies, and computational search algorithms, glycoproteomics is evolving and developing. Glycosylation is one of the most prevalent post-translational modifications, and glycoproteins are involved in a variety of biological activities, including cell signalling, host–pathogen interactions, immunological response, and illness. Glycoproteomics is a technique for determining the locations and identities of a cell's or tissue's entire glycan and glycosylated protein repertoire. Glycoproteomics, a word that refers to the simultaneous analysis of peptide and glycan sequences, is gaining traction, particularly in biomarker identification and regulatory requirements for therapeutic biopharmaceuticals, such as antibody medicines. Due to rapid technological advances in affinity enrichment, chromatographic separation, quantitation, MS methodology and instrumentation, and bioinformatics, MS-based glycoproteomics and glycomics have become an important part of biomedical research for the discovery and characterization of disease biomarkers. Glycoproteomics and glycomics techniques, which were previously separated, are becoming convergent in complex processes that better give quantitative, site-specific structural characterisation of glycoforms that could serve as true disease biomarkers. As the field progresses, this unification will become increasingly important in order to leverage new technology advancements in order to accurately characterise disease phenotypes, identify pharmacological targets, and create treatments.
