| - | [https://www.uniprot.org/uniprot/CAS2_CONST CAS2_CONST] Alpha-conotoxins act on postsynaptic membranes, they bind to the nicotinic acetylcholine receptors (nAChR) and thus inhibit them (PubMed:1390774). This toxin potently inhibits the rodent muscle nAChR (IC(50)=120 nM (adult subtype, alpha-1-beta-1-delta-epsilon/CHRNA1-CHRNB1-CHRND-CHRNE) and IC(50)=370 nM (fetal subtype, alpha-1-beta-1-gamma-delta/CHRNA1-CHRNB1-CHRNG-CHRND)) and weakly inhibits neuronal nAChRs (PubMed:35357806). In contrast to alpha-conotoxins bearing 2 disulfide bonds (framework I), this conotoxin acts via a unique binding mode with the helix and the N- and C-termini buried in the binding pocket of muscle nAChRs (PubMed:35357806).<ref>PMID:1390774</ref> <ref>PMID:35357806</ref> | ||
