MeuTXKbeta3 inhibits voltage-gated potassium channels. The synthetic meucin-24 inhibits the development of P. berghei ookinetes, kills intraerythrocytic P.falciparum, and is cytotoxic to the Drosophila S2 cell at micromolar concentrations. No antibacterial, antifungal and hemolytic activities have been found at micromolar concentrations. Expressed by the venom gland. The RNA coding for this protein is silently edited. Meucin-24 belongs to the non-disulfide-bridged peptide (NDBP) superfamily. Antimalarial peptide (group 5) family. Belongs to the long chain scorpion toxin family. Class 2 subfamily. It is uncertain whether Met-1 or Met-2 is the initiator.
