Muscle-type nicotinic receptor
From Wikipedia, the free encyclopedia
The muscle-type nicotinic receptor is a type of nicotinic acetylcholine receptor consisting of the subunit combination (α1)2β1δε (adult receptor) or (α1)2β1δγ (fetal receptor).[1] These receptors are found in neuromuscular junctions, where activation leads to an excitatory postsynaptic potential (EPSP), mainly by increased Na+ and K+ permeability.
