[https://www.uniprot.org/uniprot/TXMG5_MACGS TXMG5_MACGS] Insect and vertebrate active toxin. Binds to site 4 of mammalian voltage-gated sodium channels and shifts the activation voltage of the mammalian Nav1.2a/SCN2A channel to more hyperpolarized voltages, whereas the insect channel, DmNav1 (para), is not affected. Competes for binding at site 3 of the insect sodium channel. Causes temporary paralysis when injected into lepidopteran larvae at 8.6 nmol/g. A low intracranial injection dose into mice causes lacrimation, closure of the eyes and sweating. A high injection dose causes extensive lacrimation and death.<ref>PMID:12860384</ref> | |||
