What we do

In the Proteome Informatics Group (PIG), we are involved in software and database development for the benefit of the proteomics and glycomics communities. These resources are made available through the ExPASy server. Software tools support experimental mass spectrometry data analysis, mainly for the detection of posttranslational modifications, with a strong focus on glycosylation. We also develop integrated tools and databases to query knowledge of carbohydrates attached to proteins, carbohydrate structures and protein-carbohydrate interactions.

The group develops the Glycomics@ExPASy tool.

Highlights 2017

In recent years, we have set out to collect and integrate information on carbohydrates/glycans, whose role is increasingly described as key in many normal and pathological cellular processes. With the creation of a dedicated tab on the ExPASy server in 2015, we now centralize databases and tools that are useful for glycomics and glycoproteomics and are gradually expanding our range. In 2017, we introduced three new tools:

  • Glynsight, a web interface to upload, visualize and interactively compare glycan expression profiles;
  • EpitopeXtractor, a tool that extracts glycan determinants (binding motifs) from a list of glycan structures and maps their shared features;
  • Glyconnect, a platform integrating several sources of information to characterize the molecular actors of glycosylation, mainly glycoproteins and N- and O-linked glycans.
