Title of diploma thesis: Characetrization of ligand binding to M1 muscarinic receptor using fluorescence anisotropy method Muscarinic acetylcholine receptors (mAChRs), members of the superfamily of G-protein coupled receptors (GPCRs), regulate vital physiological processes and are important targets in drug research. Five different subtypes (M1 - M5) have been identified. M1 mAChR is mainly distributed in the central nervous system and is linked to pathophysiology of neurodegenerative diseases. In recent years, fluorescent methods have been frequently used in studies of ligand binding to receptors. The fluorescence anisotropy (FA) is a homogenous assay to characterize ligand binding to receptors. In this work, we have evaluated the FA method with fluorescent ligand MK342 binding to M1 mAChRs expressed on budded baculovirus (BBV) particles. The fluorescence ligand was binding with the high affinity (4,4 nM) to M1 receptor in constructed BBV preparation. The apparent binding affinities (pKi) of eleven classical and three bitopic muscarinic ligands were screened and compared to previously published...
