| + | [https://www.uniprot.org/uniprot/3SIM2_DENAN 3SIM2_DENAN] Binds irreversibly to M1 (CHRM1) muscarinic acetylcholine receptors, and reveals a slightly weaker effect on M3 (CHRM3) receptors. The mechanism of toxin-receptor interaction comprises at least two steps. The first step is fast with no competition between the toxin and the antagonist. The second step is slow with formation of a more stable toxin-receptor complex and inhibition of the antagonist binding.<ref>PMID:7778123</ref> | ||
