UniProtKB - P21150 (SIX4_ANDAU)
Protein
Toxin AaHIT4
Gene
N/A
Organism
Androctonus australis (Sahara scorpion)
Status
Functioni
Has a toxic effect on insects and mammals and is capable of competing with anti-insect scorpion toxins for binding to the sodium channel (Nav) of insects. It also modulates the binding of alpha-type and beta-type anti-mammal scorpion toxins to the mammal sodium channel. It may act on both site 3 and site 4 of voltage-gated sodium channels.
