Summary: 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, Nov 2024]

The numbers of nAChR alpha4 immuno-positive cells and western blot levels were significally increased by 15-Hz auricular electrical stimulation in the hippocampal CA2 output cortex. The numbers of choline acetyltransferase (ChAT) - a key enzyme for biosynthesis of ACh - immuno-positive cells and western blot levels had no significant differences.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
