  1. Bioinformatics Core (B)Progress and Future Goals www.functionalglycomics.org

  2. Challenges • Chemical heterogeneity • Challenges in isolation and analysis • Challenges in representation/processing glycan Information Non-template biosynthesis Ensemble or group of glycan structures resulting from coordinated expression of several biosynthetic enzymes Glycan-Protein Interaction • Challenges • Understanding biochemical basis for glycan-protein interactions • How glycan specific genotype governs whole organism phenotype • Constructing biological pathways and interaction networks Multivalent interactions involving multiple glycan motifs with multivalent CRDs on proteins Advancing GlycomicsKey Issues & Challenges Glycan Structure-Function Relationships

  3. Consortium for Functional Glycomicswww.functionalglycomics.org • Active collaborative effort to advance glycomics • Goal: Understand role of glycan–protein interactions in cell-cell communication • Develop technologies and resources to obtain data at various levels from molecule  mouse • Integrated approach to glycan structure-function

  4. Static Pages (SHTML) for Web Site Dynamic pages (JSPs) for database driven Entry, Dissemination and Queries Middleware implemented using Entity-Class Operations, Servlets in Java Object-based Relational Database implemented using Oracle Part of CFG database overall ontology map Bioinformatics Core (B)Vision & Approach • Vision:Present the dynamic “face” of the Consortium via Internet to best utilize the value of the resources and datasets generated by its participants and the broader scientific community.

  5.
