GlyGen (gly-glycobiology; gen-information), is an advanced glycoinformatics resource developed to facilitate discovery in basic and translational glycobiology research along with enhancing the integration of multidisciplinary information from diverse resources. GlyGen will include knowledge about molecular, biophysical and functional properties of glycans, genes, and proteins organized in pathways and ontologies, plus a rapidly growing body of biological big data related to cancer mutation and expression. GlyGen adopts an innovative user driven approach for implementing, prioritizing and knowledge disseminating tools to address the questions and needs of glycobiology community.
