Protein
Muscarinic acetylcholine receptor M3
Gene
Chrm3
Organism
Mus musculus (Mouse)
Status
Functioni
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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:| 100% | UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry. |
| 90% | UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence). |
| 50% | UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster. |
