== Function ==
[https://www.uniprot.org/uniprot/3SIMA_DENPO 3SIMA_DENPO] Selectively binds with high-affinity to the a2B-adrenoceptor subtype (ADRA2B) (PubMed:20466015). The toxin reversibly binds to ADRA2B, and its mode of inhibition is non-competitive (PubMed:20466015). The toxin has also been described to bind with high affinity to all muscarinic receptor subtypes (Ki=23 nM (on CHRM1), Ki=44 nM (on CHRM2), Ki=3 nM (on CHRM3), Ki=5 nM (on CHRM4), and Ki=8 nM (on CHRM5)) but no other data support these affinity values (PubMed:8536706).<ref>PMID:10978757</ref> <ref>PMID:20466015</ref> <ref>PMID:21557730</ref> <ref>PMID:8536706</ref>
