[https://www.uniprot.org/uniprot/LECF_ASPFU LECF_ASPFU] Multispecific lectin that is able to recognize L-fucose in all possible linkages (PubMed:23695231, PubMed:27058347, PubMed:24340081, PubMed:25760594). These could be found not only in decomposed plant matter in soil, which is the natural environment for A.fumigatus, but also in various epitopes on human tissues (PubMed:25760594). Mediates binding of A.fumigatus conidia to airway mucinin a fucose dependent manner (PubMed:27058347). Stimulates IL-8 production by human bronchial cells in a dose-dependent manner, contributing to the inflammatory response observed upon the exposure of a patient to A.fumigatus, and thus might be an important virulence factor involved in an early stage of A.fumigatus infection (PubMed:24340081).<ref>PMID:23695231</ref> <ref>PMID:24340081</ref> <ref>PMID:25760594</ref> <ref>PMID:27058347</ref>

== Publication Abstract from PubMed ==
 +
The Aspergillus fumigatus lectin AFL was recently described as a new member of the AAL lectin family. As a lectin from an opportunistic pathogen, it might play an important role in the interaction of the pathogen with the human host. A detailed study of structures of AFL complexed with several monosaccharides and oligosaccharides, including blood-group epitopes, was combined with affinity data from SPR and discussed in the context of previous findings. Its six binding sites are non-equivalent, and owing to minor differences in amino-acid composition they exhibit a marked difference in specific ligand recognition. AFL displays a high affinity in the micromolar range towards oligosaccharides which were detected in plants and also those bound on the human epithelia. All of these results indicate AFL to be a complex member of the lectin family and a challenging target for future medical research and, owing to its binding properties, a potentially useful tool in specific biotechnological applications.
