Enables acetylcholine binding activity; acetylcholinesterase activity; and choline binding activity. Involved in several processes, including acetylcholine catabolic process; positive regulation of neurogenesis; and response to insulin. Located in several cellular components, including endoplasmic reticulum; neuronal cell body; and synaptic membrane. Is active in neuromuscular junction and synaptic cleft. Biomarker of acute stress disorder and leptospirosis. Human ortholog(s) of this gene implicated in Alzheimer's disease; epilepsy; and myasthenia gravis. Orthologous to human ACHE (acetylcholinesterase (Cartwright blood group)). [provided by Alliance of Genome Resources, Apr 2022]
