The GlySpace Alliance was formed in 2018 among the principal investigators of three major glycoscience portals: Glyco@Expasy, GlyCosmos, and GlyGen, representing Europe, Asia, and the United States, respectively. The members of the GlySpace Alliance have developed their respective resources from various perspectives. In short, Glyco@Expasy aims to provide data from the user’s view along the lines of Expasy’s approach. At the same time, GlyCosmos attempts to provide extensive coverage of glycan-related omics data, and GlyGen focuses on integration with genes, proteins, and other data types.
While each portal has a unique user interface, the aim is to provide the same primary data set of glycan-related omics data. These portals will be introduced to enable users to find their target information in the most efficient manner, in particular, in terms of the chemical structures of glycans and their functions.
