Function

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.

Involvement in disease

Prune belly syndrome

PBS

A syndrome characterized by thin abdominal musculature with overlying lax skin, cryptorchism, megacystis with disorganized detrusor muscle, and urinary tract abnormalities.

None

The disease is caused by variants affecting the gene represented in this entry.

Sequence similarities

Belongs to the G-protein coupled receptor 1 family. Muscarinic acetylcholine receptor subfamily. CHRM3 sub-subfamily.

Cellular localization

  • Cell membrane
  • Multi-pass membrane protein
  • Postsynaptic cell membrane
  • Multi-pass membrane protein
  • Basolateral cell membrane
  • Multi-pass membrane protein
  • Endoplasmic reticulum membrane
  • Multi-pass membrane protein
  • Colocalizes with TMEM147 in the endoplasmic reticulum (ER) membrane. TMEM147 impairs its trafficking to the cell membrane leading to its retention in the ER membrane.
