Abstract
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.

) / Eur. J. Biochem. by Woods R. J. (1998) - The weak interaction with a GlcNAc-terminated neoglycolipid derived from an asialo aglacto-bantennary N-linked glycan can be explained by the interaction of a terminal GlcNAc residue with the principal Ca 2+ site as observed in the cross-linked pairs of CRDs of DC-SIGN (Fig. 3B). This interpretation is confirmed by the observation that the corresponding galactose-terminated structure in which the 4-OH of GlcNAc is inaccessible does not bind at all. Moreover modeling of a further mannose residue in α1-2 linkage to the Manα1-3Man arm of the trimannosyl moiety suggests that it would pack against Val 351 of DC-SIGN whereas no contact would be made with the smaller Ser 363 present at this position of DC-SIGNR. This observation may be related to the larger affinity difference between Man 9 and smaller oligosaccharides displayed by DC-SIGN relative to DC-SIGNR [see (4) and table 2 of supplemental data (11)].
