Competing Interests

CHC and CF were full-time employees of Eli Lilly at the time the experiments were performed and the GTP-γ-[35S] binding experiments included in this manuscript have been financially supported by Eli Lilly. FB was employed at Euthymics Bioscience Inc. The muscarinic compounds BuTAC, PTAC and xanomeline used in the study, were synthesized at Eli Lilly. There are no further patents, products in development or marketed products to declare. This does not alter the authors' adherence to all the PLOS ONE policies on sharing data and materials.
