Characterization of the mature protein complement in cells is crucial for a better understanding of cellular processes on a systems-wide scale. Toward this end, we used single-dimension ultra-high-pressure liquid chromatography mass spectrometry to investigate the comprehensive "intact" proteome of the

General anesthetics exert many of their CNS actions by binding to and modulating membrane-embedded pentameric ligand-gated ion channels (pLGICs). The structural mechanisms underlying how anesthetics modulate pLGIC function remain largely unknown. GLIC, a prokaryotic pLGIC homologue, is inhibited by general
