Function

LECF_ASPOR Lectin that specifically binds to L-fucose and weakly reacts with mannose and N-acetyl-neuraminic acid (PubMed:12092808, PubMed:27318092, PubMed:28041800). Has strongest preference for the alpha-1,6-fucosylated chain (core fucose) on glycoproteins among alpha-1,2-, alpha-1,3-, alpha-1,4-, and alpha-1,6-fucosylated chains (PubMed:17383961, PubMed:19109923). Binds to fucose residues of IgE in mice and human, causing antigen-independent IgE-mediated mast cell activation and anaphylactoid reactions in mice and is possibly implicated in allergic response to Aspergillus oryzae in humans (PubMed:21790704). Induces secretion of pro-inflammatory cytokines IL6 and IL8 implicated in ocular diseases such as mycotic keratitis, probably through its interaction with host toll-like receptors TLR2 and TLR4, followed by up-regulation of pro-inflammatory cytokines (PubMed:28470344).^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7]

Publication Abstract from PubMed

Selenium-incorporated fucoses (seleno-fucoses) differing in the position of the seleno-substituent were synthesized and applied to the X-ray structural determination of a carbohydrate-lectin complex using single/multi-wavelength anomalous dispersion (SAD/MAD) phasing. The hydroxyl groups at the C-1, -2, -3 and -4 position of fucose were individually substituted with a methylseleno group via a transacetalization reaction using MeSeCH2OBn or by an SN2 reaction with TolSe- equivalents to afford the corresponding MeSe-fucose. The three-dimensional structures of a fucose-binding lectin complexed with several of these MeSe-fucoses have been determined by SAD/MAD phasing by utilizing the diffraction of selenium in the bound MeSe-fucoses.
