Atropine 118-126 cholinergic receptor muscarinic 1 Homo sapiens 4-9 19841475-7 2010 The effect of atropine on the L430A/L431A receptor mutant suggests that L(430) and L(431) play a role in folding hM(1) receptors, which is necessary for exit from the ER. Atropine 14-22 cholinergic receptor muscarinic 1 Homo sapiens 113-118 19841475-8 2010 Using site-directed mutagenesis, we also identified amino acid residues at the base of transmembrane-spanning domain 1 (TM1), V(46) and L(47), that, when mutated, reduce the plasma membrane expression of hM(1) receptors in an atropine-reversible manner. Atropine 226-234 cholinergic receptor muscarinic 1 Homo sapiens 204-209 8905341-3 1996 Using recombinant human muscarinic acetylcholine receptors (m1 and m5) and the functional assay, receptor selection and amplification technology (R-SAT), we have now shown that co-administration of the full agonist, carbachol, and a competitive antagonist, atropine or pirenzepine, at fixed ratios display functional partial agonism. Atropine 257-265 cholinergic receptor muscarinic 1 Homo sapiens 24-69
