GlycoDomainViewer: A bioinformatics tool for contextual exploration of glycoproteomes

Abstract

The GlycoDomainViewer is a bioinformatic tool to aid in the mining of glycoproteomic datasets from different sources and facilitate incorporation of glycosylation into studies of protein structure and function. We present a version 2.0 of GlycoDomainViewer incorporating a number of advanced features, which enhances visibility and accessibility of the wealth of glycoproteomic data being generated. The GlycoDomainViewer enables visual exploration of glycoproteomic data, incorporating information from recent N- and O-glycoproteome studies on human and animal cell lines and some organs and body fluids. The initial data comprises sites of glycosylation for N-linked, O-GalNAc, O-Fucose, O-Xyl, O-Mannose (in both human and yeast) and cytosolic O-GlcNAc type. The data made available via this tool will be regularly updated to improve the coverage of known glycosylation sites and datasets, reflecting the advances currently being made in characterization of glycoproteomes.
