Catalytic ActivityAcetylcholine + H(2)O = choline + acetate.
FunctionTerminates signal transduction at the neuromuscular junction by rapid hydrolysis of the acetylcholine released into the synaptic cleft. Role in neuronal apoptosis. {ECO:0000269|PubMed:11985878, ECO:0000269|PubMed:1517212, ECO:0000269|PubMed:1748670, ECO:0000269|PubMed:2714437}.
InteractionQ9Y215:COLQ; NbExp=2; IntAct=EBI-1637793, EBI-1637847; P06733:ENO1; NbExp=2; IntAct=EBI-1637793, EBI-353877; P63244:GNB2L1; NbExp=2; IntAct=EBI-1637793, EBI-296739;
PolymorphismACHE is responsible for the Yt blood group system [MIM:112100]. The molecular basis of the Yt(a)=Yt1/Yt(b)=Yt2 blood group antigens is a single variation in position 353; His-353 corresponds to Yt(a) and the rare variant with Asn-353 to Yt(b).
SimilarityBelongs to the type-B carboxylesterase/lipase family. {ECO:0000305}.
Subcellular LocationCell junction, synapse {ECO:0000269|PubMed:11985878, ECO:0000269|PubMed:1748670}. Secreted {ECO:0000250}. Cell membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
Subcellular LocationIsoform H: Cell membrane {ECO:0000250}; Lipid-anchor, GPI-anchor {ECO:0000250}; Extracellular side {ECO:0000250}.
Subcellular LocationIsoform T: Nucleus. Note=Only observed in apoptotic nuclei.
SubunitInteracts with PRIMA1. The interaction with PRIMA1 is required to anchor it to the basal lamina of cells and organize into tetramers (By similarity). Isoform H generates GPI-anchored dimers; disulfide linked. Isoform T generates multiple structures, ranging from monomers and dimers to collagen-tailed and hydrophobic-tailed forms, in which catalytic tetramers are associated with anchoring proteins that attach them to the basal lamina or to cell membranes. In the collagen-tailed forms, isoform T subunits are associated with a specific collagen, COLQ, which triggers the formation of isoform T tetramers, from monomers and dimers. Isoform R may be monomeric. {ECO:0000250, ECO:0000269|PubMed:11053835, ECO:0000269|PubMed:15526038}.
Tissue SpecificityIsoform H is highly expressed in erythrocytes. {ECO:0000269|PubMed:2714437}.
