DC-SIGN
From CFGparadigms
DC-SIGN is a C-type lectin that plays roles in both cell-cell and host-pathogen interactions, and thus serves as a model for both processes. This glycan-binding protein (GBP) paradigm also serves as a model for other members of the C-type lectin family expressed on dendritic cells.

Progress toward understanding this GBP paradigm
Carbohydrate ligands
Cellular expression
Structure
Biological roles of GBP-ligand interaction
CFG resources used in investigations
Glycan profiling
Glycogene microarray
Knockout mouse lines
Knockout mice for three potential DC-SIGN orthologues were created by the CFG and distributed to PIs, and their phenotypes were analyzed.
Glycan array
Glycan array analysis and synthetic oligosaccharides were used to elucidate DC-SIGN glycan-binding specificity and analyze the mechanism of specific glycan binding.
