Bioactivity | αC-Conotoxin PrXA is a paralytic peptide neurotoxin and a competitive nAChR antagonist, with IC50s of 1.8 nM (α1β1εδ, adult) and 3.0 nM (α1β1γδ, fetal), respectively. αC-Conotoxin PrXA competes with α-bungarotoxin at the α/δ and α/γ subunit interfaces of the nAChR, shows high specificity against neuromuscular nAChR[1]. |
