| + | [https://www.uniprot.org/uniprot/TXS2B_HORWA TXS2B_HORWA] Affects the activity of both ryanodine-sensitive calcium-release channels RyR1 and RyR2 with high potency. At lower concentrations the toxin increases full openings of the RyRs, and at higher concentrations it inhibits full openings and induce openings to subconductance levels and reduces the number of full conductance openings. The different actions may be attributed to the toxins binding at different sites on the RyRs, with binding at a high-affinity site mediating the increase in full openings and the induction of subconductance states evoked upon binding to a lower-affinity site. Insect-selective toxin that provokes a dose-dependent contractile paralysis in crickets and blowfly larvae, followed by death.<ref>PMID:21670253</ref> <ref>PMID:23671114</ref> | ||
