Gene Information

human ... ACHE(43)


Acetylthiocholine chloride has been used to determine the acetylcholine esterase activity of semen exosomes (SE). It has also been used as a substrate for acetylcholine esterase in microcalorimetric study of its kinetic parameters.

Biochem/physiol Actions

Acetylcholinesterase (AChE) enzyme plays an important physiological role in the neurotransmission process.
Acetylcholinesterase substrate and nicotinic acetylcholine receptor agonist.
