Enables acetylcholinesterase activity and protein homodimerization activity. Involved in acetylcholine catabolic process; cholinergic synaptic transmission; and regulation of locomotion. Predicted to be located in extracellular space and plasma membrane. Expressed in several structures, including command interneuron; neurons;
pm5; somatic nervous system; and tail hypodermis. Human ortholog(s) of this gene implicated in several diseases, including Alzheimer's disease; Huntington's disease; artery disease (multiple); and diabetes mellitus (multiple). Is an ortholog of human BCHE (butyrylcholinesterase).
