Muscarinic toxin 7
Muscarinic toxin 7 (MT7) is one member of a family of small peptides of 65 amino acid residues derived from the venom of African mamba snakes (Dendroaspis angusticeps), which mainly target M1-subtype of muscarinic receptor. Muscarinic toxins like the nicotinic toxins have the three-finger fold structure, characteristic of the large superfamily of toxins that act at cholinergic synapses.
