ProteomicsToxins from scratch? - Diverse, multimodal gene origins in the predatory robber fly Dasypogon diadema indicate dynamic venom evolution in dipteran insects
Venoms and the toxins they contain represent molecular adaptations that have evolved on numerous occasions throughout the animal kingdom. However, the processes that shape venom protein evolution are poorly understood because of the scarcity of whole genome data available for comparative analyses of...

ProteomicsVenom composition of the ant Tetraponera rufonigra reveals insights into the evolution of dimeric ant venom peptides
The majority of ant species are venomous, and in most lineages, peptide toxins dominate venom composition. Here we investigated the venom of the ant Tetraponera rufonigra (subfamily Pseudomyrmecinae). The major active component, Tr1a, is a homodimeric peptide that is cytolytic, activates mammalian s...

ProteomicsReduviid venom composition to inform venom evolution and evolution of blood-feeding
We found that assassin bugs from the earliest-diverging subfamily of higher Reduviidae (Peiratinae), as well as a subfamily closely related to Triatominae (Stenopodainae) have venom that is highly similar in composition to that produced by previously examined reduviids from Harpactorinae and Reduvii...

ProteomicsMultiple Evolutionary Mechanisms Underlie the Venom Composition of the Green Lacewing
Venom has independently evolved across many lineages, yet relatively few have been studied in detail, particularly among insects. Of these, Neuroptera (lacewings, antlions and relatives) remain largely unexplored, despite being widespread with agriculturally important groups such as green lacewings....

ProteomicsGenus wide venom proteomics of cobras (Naja)
Genus-wide proteomics analysis of cobra (Naja) venoms. For top-down analysis, venom samples were reduced with TCEP and measured via HPLC-MS/MS (Q-Exactive) . Spectrum-Protein matching was performed with TopPic1.1 against a genus wide translated transcriptome database and NCBI protein entries from th...

ProteomicsSaddleback caterpillar venom proteomics
Limacodidae is a family of lepidopteran insects comprising more than 1,500 species, over half of which produce pain-inducing defensive venom components in the larval stage, but little is known about their venom. Recently, we characterised proteinaceous toxins from the Australian limacodid caterpilla...

ProteomicsStings on wings: venom proteomics and tissue transcriptomics of the lesser banded hornet, Vespa affinis
The project aims at unraveling the venom repertoire of the lesser banded hornet (Vespa affinis) and investigate the regimes of natural selection underpinning their venom evolution. The study also sheds light on the clinical repercussions of the V. affinis venom.

ProteomicsPhysiological constraints dictate toxin spatial heterogeneity in snake venom glands
Venoms are ecological innovations that have evolved numerous times, on each occasion accompanied by the co-evolution of specialised morphological and behavioural characters for venom production and delivery. The close evolutionary interdependence between these characters is exemplified by animals th...

Zygaenoidea is a superfamily of lepidopterans containing many venomous species, including the Limacodidae (nettle caterpillars) and Megalopygidae (asp caterpillars). Venom proteomes have been recently documented for several species from each of these families, but further data are required to unders...

To comprehend the drivers underlying venom variation in ants, we selected 15 Neotropical species and recorded a range of traits, including ecology, morphology, and venom bioactivity. Principal component analysis of both morphological and venom bioactivity traits revealed that stinging ants display t...
