Human Gene BCHE (ENST00000264381.8)
  Description: Homo sapiens butyrylcholinesterase (BCHE), transcript variant 1, mRNA. (from RefSeq NM_000055)
RefSeq Summary (NM_000055): This gene encodes a cholinesterase enzyme and member of the type-B carboxylesterase/lipase family of proteins. The encoded enzyme exhibits broad substrate specificity and is involved in the detoxification of poisons including organophosphate nerve agents and pesticides, and the metabolism of drugs including cocaine, heroin and aspirin. Humans homozygous for certain mutations in this gene exhibit prolonged apnea after administration of the muscle relaxant succinylcholine. [provided by RefSeq, Jul 2016].

-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=Cholinesterase; EC=; AltName: Full=Acylcholine acylhydrolase; AltName: Full=Butyrylcholine esterase; AltName: Full=Choline esterase II; AltName: Full=Pseudocholinesterase; Flags: Precursor;
FUNCTION: Esterase with broad substrate specificity. Contributes to the inactivation of the neurotransmitter acetylcholine. Can degrade neurotoxic organophosphate esters.
CATALYTIC ACTIVITY: An acylcholine + H(2)O = choline + a carboxylate.
ENZYME REGULATION: Inhibited by mercury. Inhibited by Tabun. Tabun forms a covalent adduct with Ser-226 that becomes irreversible upon aging.
SUBUNIT: Homotetramer; disulfide-linked. Dimer of dimers.
TISSUE SPECIFICITY: Detected in blood plasma (at protein level). Present in most cells except erythrocytes.
DISEASE: Defects in BCHE are the cause of butyrylcholinesterase deficiency (BChE deficiency) [MIM:177400]. BChE deficiency is a metabolic disorder characterized by prolonged apnoea after the use of certain anesthetic drugs, including the muscle relaxants succinylcholine or mivacurium and other ester local anesthetics. The duration of the prolonged apnoea varies significantly depending on the extent of the enzyme deficiency. BChE deficiency is a multifactorial disorder. The hereditary condition is transmitted as an autosomal recessive trait.
SIMILARITY: Belongs to the type-B carboxylesterase/lipase family.

ModBase Predicted Comparative 3D Structure on P06276
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
