Function

PA2HL_VIPAA Snake venom phospholipase A2 homolog that is very active in inducing myonecrosis in vivo and shows a potent calcium-independent membrane-damaging activity in vitro, most probably by binding and incorporating in the membrane. Also acts as a presynaptic neurotoxin.[1] [2] [3] [4] [5] [6] [7] [8]
