CC -!- FUNCTION: The muscarinic acetylcholine receptor mediates various
CC cellular responses, including inhibition of adenylate cyclase,
CC breakdown of phosphoinositides and modulation of potassium channels
CC through the action of G proteins. Primary transducing effect is Pi
CC turnover (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer; the dimers can form tetramers (By similarity).
CC Interacts with NALCN (By similarity). Interacts with TMEM147 (By
CC similarity). {ECO:0000250|UniProtKB:P20309,
CC ECO:0000250|UniProtKB:Q9ERZ3}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P20309};
CC Multi-pass membrane protein {ECO:0000255}. Postsynaptic cell membrane
CC {ECO:0000250}; Multi-pass membrane protein {ECO:0000255}. Basolateral
CC cell membrane {ECO:0000250|UniProtKB:P20309}; Multi-pass membrane
CC protein {ECO:0000255}. Endoplasmic reticulum membrane
CC {ECO:0000250|UniProtKB:P20309}; Multi-pass membrane protein
CC {ECO:0000255}. Note=Colocalizes with TMEM147 in the endoplasmic
CC reticulum (ER) membrane. TMEM147 impairs its trafficking to the cell
CC membrane leading to its retention in the ER membrane.
CC {ECO:0000250|UniProtKB:P20309}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC Muscarinic acetylcholine receptor subfamily. CHRM3 sub-subfamily.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
