Muscarinic toxin 1

UniProtKB accession:  P81030

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Shows a non-competitive interaction with adrenergic and muscarinic receptors. Binds to alpha-2b (ADRA2B) (IC(50)=2.3 nM), alpha-1a (ADRA1A), alpha-1b (ADRA1B), and alpha-2c (ADRA2C) adrenergic receptors. Reversibly binds to M1 (CHRM1) muscarinic acetylcholine receptors, probably by interacting with the orthosteric site (PubMed:7778123, PubMed:12488533, PubMed:24793485). Also reveals a slightly weaker effect at M3 (CHRM3) and M4 (CHRM4) receptors (PubMed:7778123, PubMed:12488533, PubMed:24793485). The order of potency is ADRA2B>>CHRM1>ADRA1A>ADRA1B>ADRA2C/CHRM4 (PubMed:24793485).
