| - | + | [https://www.uniprot.org/uniprot/TXH1_CYRSC TXH1_CYRSC] Lethal toxin with multiple biological activities. Inhibits voltage-gated TTX-sensitive sodium channels in DRG neurons (IC(50)=55 nM) and also shows activity when directly tested on Nav1.7/SCN9A (IC(50)=25.1-630 nM) (PubMed:17451655, PubMed:21731778, PubMed:31234412). Inhibits N-type calcium channels (Cav2.2/CACNA1B (IC(50)=100 nM)) (PubMed:11024489, PubMed:17451655). Also blocks neuromuscular transmission (PubMed:8212049, PubMed:9028007, PubMed:10736477). In vivo, intrathecal injected toxin shows analgesic activity in the rat formalin-induced pain model, without induction of motor dysfunction in rats.<ref>PMID:15581678</ref> | |
