title: Identification and characterization of N-glycosylated proteins using proteomics.
abstract: Glycoproteins constitute a large fraction of the proteome. The fundamental role of protein glycosylation in cellular development, growth, and differentiation, tissue development, and in host-pathogen interactions is by now widely accepted. Proteome-wide characterization of glycoproteins is a complex task and is currently achieved by mass spectrometry-based methods that enable identification of glycoproteins and localization, classification, and analysis of individual glycan structures on proteins. In this chapter we briefly introduce a range of analytical technologies for recovery and analysis of glycoproteins and glycopeptides. Combinations of affinity-enrichment techniques, chemical and biochemical protocols, and advanced mass spectrometry facilitate detailed glycoprotein analysis in proteomics, from fundamental biological studies to biomarker discovery in biomedicine.
