Plants express chitinase and chitinase-like proteins (CLPs) belonging to the glycosyl hydrolases of the GH18 and GH19 families, which exhibit varied functions. CLPs in the GH18 family have been structurally and functionally characterized; however, there are no structures available for any member of the GH19 family. In this study, two CLPs of the GH19 family(More)
Scorpion venoms are a rich source of K(+) channel-blocking peptides. For the most part, they are structurally related small disulfide-rich proteins containing a conserved pattern of six cysteines that is assumed to dictate their common three-dimensional folding. In the conventional pattern, two disulfide bridges connect an α-helical segment to the(More)
The presence of serotonin 1A receptor (5-HT(1A)-R) in the hippocampus, amygdala, and most regions of the frontal cortex is essential between postnatal day-5-21 (P5-21) for the expression of normal anxiety levels in adult mice. Thus, the 5-HT(1A)-R plays a crucial role in this time window of brain development. We show that the 5-HT(1A)-R-mediated stimulation(More)
Lectins play crucial roles for innate immune responses in invertebrates by recognizing and eliminating pathogens. In this study, a lectin from the mussel Mytilus californianus (MCL) was identified and characterized. The lectin was purified by affinity chromatography in α-lactose-agarose resin showing an experimental molecular mass of 18000 Da as determined(More)
Scorpine-like peptides are two domain peptides found in different scorpion venoms displaying various antimicrobial, cytolytic, and potassium channel-blocking activities. The relative contribution of each domain to their different activities remains to be elucidated. Here, we report the recombinant production, solution structure, and antiparasitic activity(More)
The scorpion toxin tamapin displays the most potent and selective blockage against KCa2.2 channels known to date. In this work, we report the biosynthesis, three-dimensional structure, and cytotoxicity on cancer cell lines (Jurkat E6-1 and human mammary breast cancer MDA-MB-231) of recombinant tamapin and five related peptides bearing mutations on residues(More)
Oligomerization of allergens plays an important role in IgE-mediated reactions, as effective crosslinking of IgE- FcεRI complexes on the cell membrane is dependent on the number of exposed B-cell epitopes in a single allergen molecule or on the occurrence of identical epitopes in a symmetrical arrangement. Few studies have attempted to experimentally(More)
