Antagonized by alpha-bungarotoxin, it is bound to nicotinic and muscarinic receptors.  
Diisopropyl phosphofluoridate binds to the enzyme that breaks down this molecule by forming a covalent bond between the phosphorus and the hydroxyl oxygen of the serine residue of the active site, barring this molecule's entry. Its receptor has a 43K cytoplasmic protein and 5 subunits of 4 transmembrane segments, each with claw-like extracellular amino termini. The vasoline gap voltage clamp showed that it gates channels permeable to cesium, sodium, and less so to calcium. Antagonized by alpha-bungarotoxin, it is bound to nicotinic and muscarinic receptors.  FTP name this neurotransmitter of the neuromuscular junction synthesized from acetyl co-A.
