The GlycoDomainViewer brings to the community an integrative tool for glycoproteomics that enables global analysis of the interplay between protein sequences, glycosites, types of glycosylation, and local protein fold / domain and other PTM context. The GlycoDomainViewer integrates poly-Omics data sets and enables exploration and visualisation of individual glycosites on proteins from many organisms. We provide a visual representation of protein context around glycosites, automatically managing the amount of information that is drawn so that data remains comprehensible. The tool aggregates and presents data produced experimentally as well as retrieved from other databases, with a view to presenting the maximum amount of relevant protein and post-translational modification (PTM) information available to explore the possible effects of glycosylation on a protein. In order to focus upon protein context, only initiating monosaccharides are shown, with limited glycan elaboration (i.e. T structures).


The following key can be used to interpret the symbols used in the GlycoDomain Viewer. Symbol notation follows the Symbol Nomenclature for Glycans scheme. Predictions from NetOGlyc4.0 have been pre-calculated for all Human proteins, and are shown whenever data is available.

Welcome to the GlycoDomainViewer, a tool to help you answer the question of whether a protein you are interested in is glycosylated, and what that could mean for the function of the protein. To start, or
