-[https://www.uniprot.org/uniprot/ACM3_HUMAN ACM3_HUMAN] Defects in CHRM3 are the cause of Eagle-Barrett syndrome (EGBRS) [MIM:[https://omim.org/entry/100100 100100]. EGBRS is a syndrome characterized by thin abdominal musculature with overlying lax skin, cryptorchism, megacystis with disorganized detrusor muscle, and urinary tract abnormalities.<ref>PMID:22077972</ref>

-== Function ==
+Designer receptors exclusively activated by designer drugs (DREADDs) represent a powerful chemogenetic technology for the remote control of neuronal activity and cellular signalling(1-4). The muscarinic receptor-based DREADDs are the most widely used chemogenetic tools in neuroscience research. The G(q)-coupled DREADD (hM3Dq) is used to enhance neuronal activity, whereas the G(i/o)-coupled DREADD (hM4Di) is utilized to inhibit neuronal activity(5). Here we report four DREADD-related cryogenic electron microscopy high-resolution structures: a hM3Dq-miniG(q) complex and a hM4Di-miniG(o) complex bound to deschloroclozapine; a hM3Dq-miniG(q) complex bound to clozapine-N-oxide; and a hM3R-miniG(q) complex bound to iperoxo. Complemented with mutagenesis, functional and computational simulation data, our structures reveal key details of the recognition of DREADD chemogenetic actuators and the molecular basis for activation. These findings should accelerate the structure-guided discovery of next-generation chemogenetic tools.
-[https://www.uniprot.org/uniprot/ACM3_HUMAN ACM3_HUMAN] The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is Pi turnover.
