Purification and characterization of myotoxin IV, a phospholipase A2 variant, from Bothrops asper snake venom
(1995)
A basic myotoxic protein was purified from Bothrops asper venom. Like other basic Bothrops myotoxins, myotoxin IV induces acute muscle damage after intramuscular injection in mice and disrupts negatively charged liposomes ...
Venoms of Micrurus coral snakes: evolutionary trends in compositional patterns emerging from proteomic analyses
(2016-11)
The application of proteomic tools to the study of snake venoms has led to an impressive growth in the
knowledge about their composition (venomics), immunogenicity (antivenomics), and toxicity (toxicovenomics).

Anti-human erythrocyte antibodies in horse-derived antivenoms used in the treatment of snakebite envenomations
(2007-03)
This work examined the presence of antibodies reacting with human erythrocytes in horse-derived antivenoms used in the treatment of snakebite envenomations, and assessed the efficacy of various fractionation protocols in ...
Proteomic and biological characterization of the venom of the redtail coral snake, Micrurus mipartitus (Elapidae), from Colombia and Costa Rica
(2011-12)
Venoms of the redtail coral snake Micrurus mipartitus from Colombia and Costa Rica were
analyzed by “venomics”, a proteomic strategy to determine their composition. Proteins
were separated by RP-HPLC, followed by SDS-PAGE, ...
Calcium imaging of muscle cells treated with snake myotoxins reveals toxin synergism and presence of acceptors
(2009-04-17)
Snake myotoxins have a great impact on human health worldwide. Most of them adopt a phospholipase A2 fold and occur in two forms which often co-exist in the same venom: the Asp49 toxins hydrolyse phospholipids, whilst Lys49 ...
Unity makes strength: exploring intra and interspecies toxin synergism between phospholipases A2 and cytotoxins
(2020)
Toxin synergism is a complex biochemical phenomenon, where different animal venom proteins interact either directly or indirectly to potentiate toxicity to a level that is above the sum of the toxicities of the individual ...
Characterization of a basic phospholipase A2-homologue myotoxin isolated from the venom of the snake Bothrops neuwiedii (yarará chica) from Argentina
(1999)
A basic protein was isolated by CM-Sephadex C-25 chromatography from the venom of
Bothrops neuwiedii from Argentina, and named B. neuwiedii myotoxin I. This protein
exerted local myotoxic and edema-forming e ects in mice, ...
Venom characterization of the three species of Ophryacus and proteomic profiling of O. sphenophrys unveils Sphenotoxin, a novel Crotoxin-like heterodimeric β-neurotoxin
(2019)
Venoms of the three species of Ophryacus (O. sphenophrys, O. smaragdinus, and O. undulatus), a viperid genus endemic to Mexico, were analyzed for the first time in the
present work. The three venoms lacked procoagulant ...
In vivo neutralization of Myotoxin II, a phospholipase A2 homolog from Bothrops asper venom, using peptides discovered via phage display technology
(2022)
Many snake venom toxins cause local tissue damage in prey and victims, which constitutes an important pathology that is challenging to treat with existing antivenoms. One of the notorious toxins that causes such effects ...
Novel three-finger toxins from Micrurus dumerilii and Micrurus mipartitus coral snake venoms: phylogenetic relationships and characterization of Clarkitoxin-I-Mdum
(2019)
Micrurus mipartitus and M. dumerilii are the most medically important coral snakes in Colombia. Proteomic
characterization of their venoms has previously shown that proteins of the three-finger toxin (3FTx) family ...
