Bitopic binding mode of an M1 muscarinic acetylcholine receptor agonist associated with adverse clinical trial outcomes [PDF]
The realisation of the therapeutic potential of targeting the M1 muscarinic acetylcholine receptor (M1 mAChR) for the treatment of cognitive decline in Alzheimer's disease has prompted the discovery of M1 mAChR ligands showing efficacy in alleviating ...

Modulation of the M2 Muscarinic Acetylcholine Receptor Activity with Monoclonal Anti-M2 Receptor Antibody Fragments [PDF]
Antibodies directed against the second extracellular loop of G protein-coupled receptors are known to have functional activities. From a partial agonist monoclonal antibody directed against the M2 muscarinic receptor, we constructed and produced a single chain variable fragment with high affinity for its target epitope.

Intrinsic Gating Properties of a Cloned G Protein-activated Inward Rectifier K^+ Channel [PDF]
The voltage-, time-, and K^+-dependent properties of a G protein-activated inwardly rectifying K^+ channel (GIRK1/KGA/Kir3.1) cloned from rat atrium were studied in Xenopus oocytes under two-electrode voltage clamp. During maintained G protein activation

Distribution of Muscarinic Acethylcholine Receptors and Related Signal [PDF]
Muscarinic receptors are members of G protein coupled receptor family. Molecularcloning studies indicate five intronless genes that encode five muscarinic receptorglycoproteins.

Inhibition of Subsets of G Protein-coupled Receptors by Empty Mutants of G Protein α Subunits in Go, G11, and G16 [PDF]
We previously reported that the xanthine nucleotide binding Goα mutant, GoαX, inhibited the activation of Gi-coupled receptors. We constructed similar mutations in G11α and G16α and characterized their nucleotide binding and receptor interaction.

Allosteric modulation in monomers and oligomers of a G protein-coupled receptor
The M2 muscarinic receptor is the prototypic model of allostery in GPCRs, yet the molecular and the supramolecular determinants of such effects are unknown.

Probing the role of the cation–π interaction in the binding sites of GPCRs using unnatural amino acids [PDF]
We describe a general application of the nonsense suppression methodology for unnatural amino acid incorporation to probe drug–receptor interactions in functional G protein-coupled receptors (GPCRs), evaluating the binding sites of both the M2 muscarinic

Additive interaction of intrathecal ginsenosides and neostigmine in the rat formalin test [PDF]
BackgroundThe authors evaluated the effect of intrathecal mixture of ginsenosides with neostigmine on formalin-induced nociception and made further clear the role of the spinal muscarinic (M) receptors on the activity of ginsenosides.MethodsA catheter ...
