Spider venom contains a very valuable repertoire of natural resources to discover novel components for molecular diversity analyses and therapeutic applications. In this study, HWTX-XI toxins from the spider venom glands of Ornithoctonus huwena which are Kunitz-type toxins (KTTs) and were directly cloned, analyzed and functionally characterized. To date, the HWTX-XI superfamily consists of 38 members...
The spider venom is a large pharmacological repertoire composed of different types of bioactive peptide toxins. Despite the importance of spider toxins in capturing terrestrial prey and defending themselves against predators, we know little about the venom components from the spider acting on the fish. Here we constructed a cDNA library of a pair of venomous glands from a single fish-hunting spider...
By sequencing random clones from the venom gland cDNA library of the spider Ornithoctonus huwena, a transcript, named SHL-Ib1, encoding a lectin-like peptide was cloned. The amino acid sequence of the putative mature peptide of SHL-Ib1 is identical, except for seven different residues, with that of SHL-I, a lectin found in the venom of O. huwena. The mature peptides of SHL-Ib1b and SHL-Ib1c are the...
