2015). Amarant T, Burkhart W, LeVine H, Arocha-Pinango CL, Parikh I. Andersen JF, Gudderra NP, Francischetti IMB, Ribeiro JMC. Latarcins are antimicrobial and cytolytic peptides from the venom of the spider Lachesana tarabaevi that adopt an amphiphilic α-helical structure in contact with lipid membranes and show general cytotoxicity and hemolytic activity (Kozlov et al. 2007; Kim et al. 2008) for cross validation. S6, Supplementary Material online). Venom phospholipases can induce necrosis, inflammation, inhibition of blood coagulation, and blocking of the neuromuscular transmission (Kini 2003; Fry et al. One of the first hints you’re dealing with a fireworm is that you actually see it. 2009). 2015; Qian et al. The fireworm ShKT-domain toxins are grouped in a large clade that includes the bloodworm sequences and the cnidarian toxins (fig. 9). 2012; Soares et al. 2012). 2013; Gorson et al. 2010; Liu et al. Peptidase S1 are among the most diversified class of putative toxins in the fireworm transcriptomes, with 30 transcripts belonging to three orthologous clusters. 2017). 2013) was first used to predict protein-coding regions within transcripts. 1985; von Reumont et al. 2008, 2010; Borda et al. and none in S. nudus or C. olivaceus (see supplementary table S1, Supplementary Material online). 2011; Rokyta et al. The Eurythoe and Paramphinome cystatins form a strongly supported clade and are closely related to the Glycera bloodworm cystatins and the cnidarian Cyanea capillata (fig. 5). Here is a little more complicated - other components are used. The fireworm CAP homologs cluster in a clade (although with no support) that includes the rest of the annelid sequences and a few arthropod sequences (supplementary fig. The results are merged and the putative toxins validated (maroon) through BLAST and phylogenetic reconstructions to generate a final list of candidate toxins (yellow). In the venom, peptidase S1 serine proteases show varied activities such as anticoagulation, vasodilation, smooth muscle contraction, pain, immunosuppression, and inflammation (von Reumont et al. There are three broad categories of lice that plague humans — head, body and pubic lice. Some even use electricity to cook the you-know-whats. 2017). Chmelař J, Kotál J, Langhansová H, Kotsyfakis M. Cuypers E, Peigneur S, Debaveye S, Shiomi K, Tytgat J. Darriba D, Taboada GL, Doallo R, Posada D. Fernández J, Gutiérrez JM, Calvete JJ, Sanz L, Lomonte B. Gorson JM, Verdes A, Shin H, Khawaja S, Holford M. Irving JA, Pike RN, Lesk AM, Whisstock JC. The CAP protein superfamily includes cysteine-rich secretory proteins (CRISPs), antigen 5 (Ag5), and pathogenesis-related 1 proteins (Pr-1) (Gibbs et al. The greatest diversity was found in E. complanata with 438 putative toxins representing 30 toxin classes, followed by H. carunculata with 261 putative toxins distributed in 24 toxin classes and P. jeffreysii with 169 putative toxins representing 22 toxin classes. 2006). One is to prevent firing of any undischarged nematocysts remaining on the skin, thus preventing the injury from getting worse. 2014; Modica et al. The number of transcripts that correspond to each category is shown in parenthesis. The calcareous chaetae have been hypothesized to function as hypodermic needles that deliver an active toxin, which was identified as a trimethylammonium compound that causes strong skin irritation from the species Eurythoe complanata, and was consequently named Complanine (Nakamura et al. The expression of metalloproteinase M12 and phospholipases could also explain the reported cases of local necrosis. Enter your email address to follow this blog and receive notifications of new posts by email. Following this pipeline, we identified 34 clusters of orthologous genes, representing 13 known toxin classes that have been repeatedly recruited into animal venoms. 2015; Ponce et al.
