Specific Function
| Potently and reversibly inhibits some human voltage-gated sodium channels (Nav1.1/SCN1A (IC(50)=72.0 nM), Nav1.2/SCN2A (IC(50)=75.5 nM), Nav1.6/SCN8A (IC(50)=115.0 nM), Nav1.7/SCN9A (IC(50)=52.7-129.5 nM), Nav1.3/SCN3A (IC(50)=306.6 nM)) (PubMed:30784059). The hNav1.7/SCN9A channel inhibition occurs without any change in steady-state inactivation- and conductance-voltage relationships (PubMed:30784059). On adult mouse DRG neurons, this toxin is approximately 1000-fold more efficient to inhibit tetrodotoxin (TTX)-sensitive than TTX-resistant sodium currents (PubMed:30784059). In vivo, this toxin exhibits analgesic effects in mice pain models (PubMed:30784059). |
