In 2015, the proteome (complete protein profile) of eastern green mamba venom was assessed and published, revealing 42 distinct proteins and the nucleoside adenosine. The predominant agents are those of the three-finger toxin family, including aminergic toxins, which act on muscarinic and adrenergic receptors, and fasciculins, which are anticholinesterase inhibitors that cause muscle fasciculation. Another prominent component is a group of proteins known as dendrotoxins; although structurally homologous to Kunitz-type protease inhibitors, they block voltage-dependent potassium channels, stimulating the release of acetylcholine and causing an excitatory effect.
