Chrm4 Gene Summary [Mouse]
Enables G protein-coupled acetylcholine receptor activity. Acts upstream of or within adenylate cyclase-inhibiting G protein-coupled acetylcholine receptor signaling pathway. Located in membrane. Is expressed in several structures, including alimentary system; eye; limb; nervous system; and reproductive system. Orthologous to human CHRM4 (cholinergic receptor muscarinic 4).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Chrm4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
