Beta toxins bind voltage-independently at site-4 of sodium channels and shift the voltage of activation toward more negative potentials thereby affecting sodium channel activation and promoting spontaneous and repetitive firing. Competes, with apparent high affinity, with anti-insect and anti-mammalian beta-toxins for binding to cockroach and rat brain synaptosomes, respectively. Also competes with an anti-mammalian alpha-toxin on binding to rat brain sodium channels. Has a weak effect on cardiac sodium channels and a marked effect on rat brain and skeletal muscle sodium channels.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eUse of recombinant standards to improve assay calibration and cross-study comparability.\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eBeta toxins bind voltage-independently at site-4 of sodium channels and shift the voltage of activation toward more negative potentials thereby affecting sodium channel activation and promoting spontaneous and repetitive firing.
