Radiolabeled pharmacological binding assay showed: 1 BmK AS bound specifically to a single class of non-interacting binding sites on both rat brain and cockroach nerve cord synaptosomes with high affinity and low low capacity. The association of BmK AS with both synaptosomes was quick to reach equilibrium, but the dissociation seemed to be only partial. The specific binding of BmK AS was independent of membrane potential, and couldn't be modified by veratridine. Moreover, the binding of BmK AS could be inhibited by native BmK AS, BmK AS1, BmK IT2 and BmK IT on both synaptosomes, but not or partially inhibited by BmK Ⅰ and suggesting BmK AS type neurotoxins might bind to a distinct receptor site on mammal and insect sodium channels with a similar manner from β-scorpion toxins.
