Mouse Monoclonal Antibody
Manufacturer: BD Biosciences 610989
Acetylcholine is an amine neurotransmitter at the neuromuscular junction. It is released from the presynaptic membrane of a cholinergic synapse into the synaptic cleft. It diffuses across the cleft and binds acetylcholine receptors (AChR) on the postsynaptic membrane. Receptor binding induces postsynaptic membrane depolarization and the generation of an action potential that produces effects such as muscle contraction. The AChR is a 250kDa pentameric complex of four transmembrane subunits in a stoichiometry of α2βγδ. In response to ligand binding, all subunits participate in the formation of an integral cation channel. However, the acetylcholine binding site is primarily within the α subunit. Myasthenia gravis (MG) is an autoimmune condition in which AchR levels are decreased. Autoantibodies bind and crosslink the AchRs leading to their internalization and degradation. This results in a decreased number of functional AChRs. Patients develop muscular weakness and some voluntary muscle fatigue. However, development of MG is also affected by genetic factors. One of the allelic forms of the AChRα gene appears to significantly contribute to MG susceptibility.
