“…In subsequent studies (Cammarata et al 2007; Salerno et al 2009; Cammarata et al 2012) we established that DlFBL and SauFBL, a lectin from the gilt head sea bream ( Sparus aurata ) of similar binding properties, were both members of the F-type lectin family,and are also present in eggs (Parisi et al 2010). During affinity chromatography of D. labrax serum on L-fucose-agarose a protein peak with hemagglutinating activity that was susceptible to inhibition by L-rhamnose and D-galactose but not by L-fucose was identified, suggesting that this was a serum lectin distinct from DlFBL.…”

The discovery of rhamnose-binding lectins (RBLs) in teleost fish eggs led to the identification of a novel lectin family characterized by a unique sequence motif and a structural fold, and initially proposed to modulate fertilization. Further studies of the RBL tissue localization and gene organization were also suggestive of role(s) in innate immunity. Here we describe the purification, and biochemical and functional characterization of a novel RBL (DlRBL) from sea bass (Dicentrarchus labrax) serum. The purified DlRBL had electrophoretic mobilities corresponding to 24 kDa and 100 kDa under reducing and non-reducing conditions, respectively, suggesting that in plasma the DlRBL is present as a physiological homotetramer. DlRBL subunit transcripts revealed an open reading frame encoding 212 amino acid residues that included two tandemly-arrayed carbohydrate-recognition domains, and an 18-residue signal sequence at the N-terminus. The deduced size of 24.1 kDa for the mature protein was in good agreement with the subunit size of the isolated lectin. Binding activity of DlRBL for rabbit erythrocytes could be inhibited in the presence of rhamnose or galactose, did not require calcium, and was optimal at around 20°C and within the pH 6.5–8.0 range. DlRBL agglutinated Gram positive and Gram negative bacteria, and exposure of formalin-killed E. coli to DlRBL enhanced their phagocytosis by D. labrax peritoneal macrophages relative to the unexposed controls. Taken together, the results suggest that plasma DlRBL may play a role in immune recognition of microbial pathogens and facilitate their clearance by phagocytosis.

“…As the single-CRD AAA can form dimers, it is also possible that recognition of topologically similar ligands on the microbial and host cell surfaces can also lead to opsonization. 16 Exposure of bacteria to the FTLs, DlFBL and SauFBL, enhanced phagocytosis 23,31 and supports the notion that these lectins mediate innate immune functions as opsonins by cross-linking microbial pathogens to phagocytic host cells. 16,29 Variability of critical residues in the binding pocket and surrounding loops in the multiple isoforms 28 expressed in the Japanese eel FTL 15 suggests that alternative interactions with terminal and subterminal sugars may expand the range of diverse oligosaccharides recognized by the lectin isoform repertoire.…”

Furthermore, based on the DlFBL cDNA sequence, we showed that it is a bona fide FTL, as it shares carbohydrate specificity and biochemical properties with other well-characterized FTLs.…”

Parisi University of Palermo, Palermo, Italy Gerardo R. Vasta University of Maryland School of Medicine, Baltimore, MD, United States c0018 INTRODUCTIONThe term "lectin" is commonly used to encompass a wide variety of carbohydrate-binding proteins, widely distributed in viruses, prokaryotes, and eukaryotes. 1 The first invertebrate lectins were described in the early 1900s in the snail Helix pomatia, 2 the horseshoe crab Limulus polyphemus, 3 and the lobster Homarus americanus. 3 Among the vertebrates, Watkins and Morgan 4 first described an l-fucose-specific lectin in the European eel Anguilla anguilla, which led to the discovery of the carbohydrate nature of the H blood substance. Animal lectins are grouped in various molecular families, differing in carbohydrate recognition domain (CRD) structure and organization. 1,[5][6][7] Based on their CRD sequence motifs and cation requirements, animal lectins can be categorized in several families, such as C-type lectins (CTLs), galectins (formerly S-type lectins), rhamnose-binding lectins (RBLs), F-type lectins (FTLs), X-type lectins (XTLs), I-type lectins, P-type lectins, and pentraxins. 1,[5][6][7] Lectins are involved in a variety of key biological processes ranging from development to immune responses. 1,[7][8][9][10][11] The roles of lectin-carbohydrate interactions in self/non-self recognition in early dev...
