| Specific Function
| Snake venom phospholipase A2 that may have a strong anticoagulant activity (PubMed:21185324). Is able to suppress the acetylcholine (ACh)-evoked current mediated by alpha-7-similar nAChRs in L.stagnalis neurons (IC(50)=10.5 uM) and to compete with alpha-bungarotoxin for binding to muscle- and alpha-7 neuronal nAChR types, as well as to AChBPs (PubMed:25522251). In inhibition of alpha-bungarotoxin binding, this toxin is mostly active against T.californica nAChR (IC(50)=0.26 uM), it is moderately active against human alpha-7 nAChR (IC(50)=14 uM), and is not active against L.stagnalis and A.californica AChBP (IC(50)>30 uM) (PubMed:25522251). |
