  • Title: Charybdotoxin blocks cation-channels in the vacuolar membrane of suspension cells of Chenopodium rubrum L.
    Author: Weiser T, Bentrup FW.
    Journal: Biochim Biophys Acta; 1991 Jul 01; 1066(1):109-10. PubMed ID: 1712231.
    Abstract:
    Using the patch-clamp technique, we studied the action of charybdotoxin which blocks Ca(2+)-activated large-conductance K+ channels in animal tissue on the slow-activating (SV), Ca(2+)-activated cation channel in the vacuolar membrane of suspension-cells of Chenopodium rubrum L. The toxin reversibly reduced the vacuolar current with EC50 approximately 20 nM suggesting structural similarities between ion channels in animal and plant membranes.
