1 Identification of nicotinic acetylcholine receptor amino acids photolabeled by the volatile anesthetic halothane. Halothane cholinergic receptor nicotinic alpha 4 subunit Homo sapiens
2 To identify inhalational anesthetic binding domains in a ligand-gated ion channel, we photolabeled nicotinic acetylcholine receptor (nAChR)-rich membranes from Torpedo electric organ with [(14)C]halothane and determined by Edman degradation some of the photolabeled amino acids in nAChR subunit fragments isolated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and high-performance liquid chromatography. Halothane cholinergic receptor nicotinic alpha 4 subunit Homo sapiens
3 Halothane photolabeling of deltaTyr-228 provides initial evidence that halothane and isoflurane bind within this pocket with occupancy or access increased in the nAChR desensitized state compared to the closed channel state. Halothane cholinergic receptor nicotinic alpha 4 subunit Homo sapiens
4 Halothane photolabeling of deltaTyr-228 provides initial evidence that halothane and isoflurane bind within this pocket with occupancy or access increased in the nAChR desensitized state compared to the closed channel state. Halothane cholinergic receptor nicotinic alpha 4 subunit Homo sapiens
