== Function ==
[https://www.uniprot.org/uniprot/LAIT1_LIOAU LAIT1_LIOAU] 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 (By similarity). Shows insect lethality against crickets and common cutworms (only shows paralysis against cockroaches), but no toxicity is observed in mice.<ref>PMID:17681581</ref> <ref>PMID:21782787</ref>
