Description
Brevetoxin B (Brevetoxin-2; PbTx-2) is a polyketide neurotoxin produced by Karenia species and other dinoflagellates. Brevetoxin B binds to site 5 on the alpha subunit of voltage-gated sodium channels (IC50=15 nM) on neurons at the neuromuscular junction, causing the channel to open irreversibly at potentials more negative than normal, discharging action potentials repetitively.
