Toxin CsEv3

UniProtKB accession:  P01494

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Beta toxins bind voltage-independently at site-4 of sodium channels (Nav) and shift the voltage of activation toward more negative potentials thereby affecting sodium channel activation and promoting spontaneous and repetitive firing (By similarity). Induces immediate paralysis in crickets after injection, with a total paralysis occurring within 15-30 minutes and lasting for 1-2 hours. Is also lethal to vertebrate (chicks) when injected in very high dosages (more that 100 mg/kg).
