Term:
acetylcholine signaling pathway via muscarinic acetylcholine receptors engaging G alphaq protein family
Acetylcholine signaling via receptor type M1, M3 and M5 primarily engages G alphaq protein family resulting in activation of phospholipase C and mobilization of intracellular calcium. The receptors are expressed in various areas of the brain and the cell membrane of effector tissues.
