Chat Gene Summary [Mouse]
Enables choline O-acetyltransferase activity. Acts upstream of or within several processes, including adult walking behavior; establishment of synaptic specificity at neuromuscular junction; and rhythmic excitation. Located in axon; cytoplasm; and neuronal cell body. Is expressed in several structures, including alimentary system; cranium; heart; nervous system; and retina. Used to study congenital myasthenic syndrome 6. Human ortholog(s) of this gene implicated in Alzheimer's disease and congenital myasthenic syndrome 6. Orthologous to human CHAT (choline O-acetyltransferase). [provided by Alliance of Genome Resources, Jul 2025]

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 Chat often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
