Product details:
Acetylcholinesterase is the main cholinesterase enzyme in the nervous system. It is responsible for the hydrolysis of acetylcholine and some other choline esters that function as neurotransmitters. AChE is highly expressed in both the brain and the peripheral nervous system. It is especially enriched at neuromuscular junctions, where its activity serves to terminate synaptic transmission between motor neurons and skeletal muscles. Reversible inhibitors of AChE (such as donepezil, rivastigmine and galantamine) are commonly used in the treatment of Alzheimer's Disease and other neurodegenerative disorders. However, irreversible inhibitors of AChE tend to be extremely poisonous, causing muscular paralysis, convulsions, bronchial constriction and eventual death by asphyxia.
This product is manufactured by BioVision, an Abcam company and was previously called K197 Acetylcholinesterase Inhibitor Screening Kit (Colorimetric). K197-100 is the same size as the 100 test size of ab283363.

Acetylcholinesterase also known as AChE is an enzyme with a molecular mass of approximately 67 kDa. It plays a critical role in neurotransmission by catalyzing the hydrolysis of the neurotransmitter acetylcholine into acetate and choline. This reaction occurs at neuromuscular junctions and cholinergic synapses therefore terminating synaptic transmission. AChE is highly expressed in muscle and brain tissue particularly in the synaptic cleft where it regulates the nerve signal terminations.
Biological function summary
Acetylcholinesterase is essential for maintaining neurotransmission dynamics by ensuring timely acetylcholine breakdown. It does not function as part of a larger enzyme complex but its activity is necessary for efficient synaptic signaling in the nervous system. This enzymatic action prevents continuous stimulation of muscles and nerves by rapidly degrading acetylcholine thereby ensuring proper muscle contraction and cognitive processes.
Pathways
Acetylcholinesterase participates significantly in the cholinergic system. It influences cholinergic signaling pathways by inactivating acetylcholine after its release into the synaptic cleft. This function aligns acetylcholinesterase closely with receptors like nicotinic and muscarinic acetylcholine receptors. It indirectly affects signal transduction pathways that involve these receptors with potential downstream effects on ion channels and intracellular messengers.
Acetylcholinesterase plays a significant role in Alzheimer's disease and myasthenia gravis. In Alzheimer's disease decreased acetylcholinesterase function can lead to accumulations of acetylcholine and disrupted signaling contributing to cognitive dysfunction. Acetylcholinesterase inhibitors are therapeutic in such contexts. For myasthenia gravis a disorder affecting neuromuscular transmission the enzyme’s interaction with antibodies targets synaptic acetylcholine receptors. This interaction results in weakened muscle contractions correlating with condition severity.
