GO Classification	Functions acetylcholine receptor activity cation transmembrane transporter activity acetylcholine-activated cation-selective channel activity Processes skeletal muscle contraction synaptic transmission synaptic transmission, cholinergic neuromuscular synaptic transmission response to nicotine regulation of membrane potential muscle contraction cation transmembrane transport neurological system process transport signal transduction Components postsynaptic membrane plasma membrane cell junction integral component of plasma membrane synapse neuron projection acetylcholine-gated channel complex
General Function	Cation transmembrane transporter activity
Specific Function	After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.
