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.


CFG Participating Investigators contributing to the understanding of this paradigm

Many investigators, both CFG Participating Investigators (PIs) and non-PIs using CFG resources, have led extensive studies on DC-SIGN, particularly regarding structure-function relationships, interactions with pathogens, and signaling functions in dendritic cells.

Progress toward understanding this GBP paradigm

Carbohydrate ligands

Cellular expression


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.
