αC-conotoxin PrXA(αC-芋螺毒素PrXA)
Selective blocker of α1/β1/ε/δ and α1/β1/γ/δ nAChR subunits
乙酰膽堿受體亞基α1/β1/ε/δ 和 α1/β1/γ/δ的選擇性阻斷劑
αC-Conotoxin PrXA (AlphaC-PrXA) was originally isolated from the venom of the fish-hunting Conus parius. αC-Conotoxin PrXA is a highly specific inhibitor of the neuromuscular nAChR. It potently antagonizes mouse muscle adultα1/β1/ε/δ nAChR subunits (IC50 = 1.8 nM) as well as fetal mouse muscle α1/β1/γ/δ nAChR subunits (IC50 = 3 nM).αC-Conotoxin PrXA competes with α-bungarotoxin for binding at the α/δ and α/γ nAChR subunit interfaces (with higher affinity however for the α/δ subunit interface). The 3D structure of αC-Conotoxin PrXA is different from other conotoxins that target nAChR and it is most similar to Waglerin-1, a nAChR blocker isolated from a snake venom. αC-Conotoxin PrXA is a useful tool for investigating the structure and physiological role of nAChRs.
