Activity

Neurotoxin
FUNCTION: Neurotoxin T2 is a presynaptic neurotoxin of the venom that exhibits indirect hemolytic activity against human erythrocytes. The B chain is homologous to venom basic protease inhibitors but has no protease inhibitor activity and is non-toxic. {ECO:0000269|PubMed:14769867}.

Target
