Complex of DC-SIGNR and GlcNAc2Man3
Contents |
Overview
Dendritic cell specific intracellular adhesion molecule-3 (ICAM-3), grabbing nonintegrin (DC-SIGN), a C-type lectin present on the surface of, dendritic cells, mediates the initial interaction of dendritic cells with, T cells by binding to ICAM-3. DC-SIGN and DC-SIGNR, a related receptor, found on the endothelium of liver sinusoids, placental capillaries, and, lymph nodes, bind to oligosaccharides that are present on the envelope of, human immunodeficiency virus (HIV), an interaction that strongly promotes, viral infection of T cells. Crystal structures of carbohydrate-recognition, domains of DC-SIGN and of DC-SIGNR bound to oligosaccharide, in, combination with binding studies, reveal that these receptors selectively, recognize endogenous high-mannose oligosaccharides and may represent a new, avenue for developing HIV prophylactics.
Disease
Known disease associated with this structure: SARS infection, protection against OMIM:[605872]
