Beta-insect excitatory toxin BmK IT-AP

UniProtKB accession:  O77091

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Excitatory insect beta-toxins induce a spastic paralysis (PubMed:10400300). They 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. In vivo, induces paralysis on insects (PubMed:11042276). When tested on mice, it does not show toxicity but has an analgesic effect (PubMed:10400300).
