CC   -!- FUNCTION: Rapidly hydrolyzes choline released into the synapse.
CC       {ECO:0000305}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=acetylcholine + H2O = acetate + choline + H(+);
CC         Xref=Rhea:RHEA:17561, ChEBI:CHEBI:15354, ChEBI:CHEBI:15355,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30089; EC=3.1.1.7;
CC         Evidence={ECO:0000269|PubMed:12736674};
CC   -!- SUBCELLULAR LOCATION: Synapse {ECO:0000250}. Secreted {ECO:0000250}.
CC       Cell membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
CC   -!- POLYMORPHISM: A number of strains are susceptible to insecticides while
CC       others are resistant. Insensitivity to insecticides results from a loss
CC       of sensitivity of acetylcholinesterase to organophosphates and
CC       carbamates and is due to a variant at position 97.
CC       {ECO:0000269|PubMed:12736674}.
CC   -!- SIMILARITY: Belongs to the type-B carboxylesterase/lipase family.
CC       {ECO:0000305}.
