General annotation (Comments)

Function

Rapidly hydrolyzes choline released into the synapse. It can hydrolyze butyrylthiocholine.

Catalytic activity

Acetylcholine + H2O = choline + acetate.

Subunit structure

Oligomer composed of disulfide-linked homodimers By similarity.

Subcellular location

Cell junction › synapse By similarity. Secreted By similarity. Cell membrane; Peripheral membrane protein By similarity. Note: May be secreted or membrane associated via a non-catalytic subunit.

Developmental stage

Detected at all stages. Found to be more abundant in larval stages than in embryos or adults.

Sequence similarities

Belongs to the type-B carboxylesterase/lipase family.
