The deep-rooted origin of disulfide-rich spider venom toxins. [PDF]
Elife, 2023 Spider venoms are a complex concoction of enzymes, polyamines, inorganic salts, and disulfide-rich peptides (DRPs). Although DRPs are widely distributed and abundant, their bevolutionary origin has remained elusive.

The biology and evolution of spider venoms [PDF]
Biological Reviews, 2021 ABSTRACTSpiders are diverse, predatory arthropods that have inhabited Earth for around 400 million years. They are well known for their complex venom systems that are used to overpower their prey. Spider venoms contain many proteins and peptides with highly specific and potent activities suitable for biomedical or agrochemical applications, but the key

Toxinology in the proteomics era: a review on arachnid venom proteomics [PDF]
Journal of Venomous Animals and Toxins including Tropical Diseases, 2022 The word venomics was coined to acknowledge the studies that use omics to investigate venom proteins and peptides. Venomics has evolved considerably over the last 20 years. The first works on scorpion or spider venomics were published in the early 2000’s.
