Glycoproteomics is a rapidly growing field which seeks to identify and characterise glycosylation events at a proteome scale. Over the last few years considerable effort has been made in developing new technologies, enrichment systems, and analysis strategies to enhance the quality of glycoproteomic studies. Within this review we discuss the recent developments in glycoproteomics and the current state of the art approaches for analysing glycosylated substrates. We highlight key improvements in mass spectrometry instrumentation coupled with the advancements in enrichment approaches for key classes of glycosylation including mucin-O-glycosylation, O-GlcNAc glycosylation and N-linked glycosylation which now allow the identification/quantification of hundreds to thousands of glycosylation sites within individual experiments. Finally, we summarise the emerging trends within glycoproteomics to illustrate how the field is moving away from studies simply focused on identifying glycosylated substrates to studying specific mechanisms and disease states.
