Application
Iberiotoxin, recombinant from Mesobuthus tamulus has been used as an inhibitor of large-conductance calcium-activated K+ channels to study its effect on the NLRP3 (nucleotide-binding oligomerization domain-like receptor containing pyrin domain 3) inflammasome activation in bone marrow-derived macrophages (BMDMs). It has also been used to block Ca2+- activated K+ channels to determine interleukin(IL)-1β in BMDCs following inflammasome activation.
Biochem/physiol Actions
The single chain peptide iberiotoxin (IbTX) is a selective and reversible inhibitor of high-conductance calcium-activated potassium channels (PK,Ca). It occurs naturally in the venom of the scorpion Buthus tamulus. IbTX also modulates the binding of charybdotoxin (CbTX) to smooth muscle sarcolemmal membranes in a non-competitive manner. IbTX is similar in size to CbTX and shares considerable sequence homology with CbTX. However, IbTX differs in its overall charge in having one fewer basic and four more acidic residues than CbTX.
Exhibits the same activity as the natural form of the toxin
