It inhibits the enzymatic activity of RV-4 in vitro but potentiates its lethal potency and neurotoxicity. It may facilitate the specific binding of RV-4 to its presynaptic binding sites, probably by acting as a chaperon, minimizing distraction and destruction of RV-4 en route to the site of action by reducing non-specific binding to muscle and other organs. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides.<ref>PMID:8835338</ref> [[http://www.uniprot.org/uniprot/PA24_DABRU PA24_DABRU]] Heterodimer RV-4/RV-7: acts as a presynaptic neurotoxin.<ref>PMID:1425670</ref> <ref>PMID:8835338</ref> Monomer: snake venom phospholipase A2 (PLA2) that acts as a presynaptic neurotoxin.
