The selectivity of ion channels produced by latrotoxin obtained from a black widow spider venom and by venom from the spider Steatoda paykulliana in bilayer phospholipid membrane was studied. Experimental current-voltage curves of these channels were used for the estimation of parameters of a two barrier model of their energy profiles. Selectivities of both(More)
The major toxic component of black widow spider (Latrodectus mactans tredecimguttatus) venom, alpha-latrotoxin, is known to form ionic channels in different membranes. In order to probe the extramembrane domains of alpha-latrotoxin molecule, alpha-latrotoxin channels in planar lipid membrane were treated with antibodies to latrotoxin or with pronase added(More)
