The metabotropic receptors are second messenger, G protein-coupled seven-transmembrane proteins. They are classically defined as being activated by muscarine, a toxin from the mushroom Amanita muscaria, and inhibited by atropine, a toxin from Atropa belladonna, a member of the nightshade family. Both toxins cross the blood-brain barrier poorly and were discovered primarily from their influences on postganglionic parasympathetic nervous system functions. Activation of muscarinic AChRs is relatively slow (milliseconds to seconds) and, depending on the subtypes present (M1- M5), they directly alter cellular homeostasis of phospholipase C, inositol trisphosphate, cAMP, and free calcium.

M1, M3, and M5 all signal primarily via the Galphaq G-protein and induce Ca2+ mobilization and inositol trisphosphate (IP3) production, while M2 and M4 signal via the Galphai G-protein to inhibit cyclic adenosine monophosphate (cAMP) production. PubMed:24511233

Activation of Gαi coupled muscarinic receptors leads to inhibition of adenylyl cyclase and reduction of cyclic adenosine monophosphate (cAMP) levels, promoting inhibition of voltage-gated Ca2+ channels and, thus, diminishing cell excitability PubMed:26813123

So far, five mAChR subtypes (M1– M5) have been identified and are divided into two categories based on the manner of signal transduction: M1, M3, and M5 subtypes preferentially interact with the Gq/11 family of G proteins, activating phospholipase C and mobilizing intracellular calcium, while M2 and M4 subtypes couple to the Go/i family, inhibiting adenylate cyclases and reducing intracellular cAMP levels PubMed:24590577

Impairment of 26S proteasome induced by tau can be prevented early in disease through activation of cAMP-PKA signaling, and raising the levels of cAMP with rolipram may enhance tau degradation (Myeku et al. 2016) PubMed:29626319
