Dendrotoxin
Videos
Dendrotoxins are a class of presynaptic neurotoxins produced by mamba snakes that block particular subtypes of voltage-gated potassium channels in neurons, thereby enhancing the release of acetylcholi
3D model of α-dendrotoxin. colored in red are positively charged amino acid residues in the N-terminus and the β-turn region that are believed to be important for potassium channel binding.
Sequence alignment of dendrotoxins and BPTI. Amino acid residues with similar properties are colored accordingly.
