Synthetic peptides derived from the C-terminal region of Lys49 phospholipase A2 homologues from Viperidae snake venoms: biomimetic activities and potential applications
Lys49-phospholipase A2 homologues constitute a large family of toxins present in the venoms of viperid snake species, which despite lacking catalytic activity, cause significant skeletal muscle necrosis. The main structural ...
Isolation, characterization and molecular cloning of AnMIP, a new α-type phospholipase A2 myotoxin inhibitor from the plasma of the snake Atropoides nummifer (Viperidae: Crotalinae)
A new phospholipase A2 (PLA2)-inhibitory protein was isolated from the plasma of Atropoides nummifer, a crotaline snake from Central America. This inhibitor was named AnMIP, given its ability to neutralize the activity ...
Ability of fucoidan to prevent muscle necrosis induced by snake venom myotoxins: comparison of high- and low-molecular weight fractions
Fucoidan, a natural polysaccharide extracted from brown seaweed, inhibits the myotoxic phospholipases A2 present in the venoms of crotalid snakes. This study evaluated the influence of molecular weight on the ability of ...
Differential susceptibility of C2C12 myoblasts and myotubes to group II phospholipase A2 myotoxins from crotalid snake venoms
Group II phospholipase A2 (PLA2) myotoxins isolated from Viperidae/Crotalidae snake venoms induce a rapid cytolytic effect upon diverse cell types in vitro. Previous studies suggested that this effect could be more ...
Screening for target toxins of the antiophidic protein DM64 through a gel-based interactomics approach
DM64 is a glycosylated protein with antivenomactivity isolated fromthe serum of the opossumDidelphis aurita. It binds non-covalently to myotoxins I (Asp49) and II (Lys49) from Bothrops asper venom and inhibits their myotoxic ...
