α-Dendrotoxin

α-Dendrotoxin (α-DTX) is a small molecule peptide neurotoxin isolated from the venom of the African green mamba snake (Dendroaspis angusticeps) . α-Dendrotoxin is also a KV1.1, KV1.2, KV1.6 and ASIC channel blocker. α-Dendrotoxin blocks potassium channels, lowers the threshold of neuronal action potentials, and increases the frequency of action potentials, thereby enhancing neuronal excitability. α-Dendrotoxin can be used in neurotoxicology research[1].
