Summaries for BCHE Gene

Entrez Gene Summary for BCHE Gene

  • Mutant alleles at the BCHE locus are responsible for suxamethonium sensitivity. Homozygous persons sustain prolonged apnea after administration of the muscle relaxant suxamethonium in connection with surgical anesthesia. The activity of pseudocholinesterase in the serum is low and its substrate behavior is atypical. In the absence of the relaxant, the homozygote is at no known disadvantage. [provided by RefSeq, Jul 2008]

GeneCards Summary for BCHE Gene

BCHE (Butyrylcholinesterase) is a Protein Coding gene. Diseases associated with BCHE include pseudocholinesterase deficiency and curariform drugs toxicity. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include identical protein binding. An important paralog of this gene is CES2.

UniProtKB/Swiss-Prot for BCHE Gene

  • Esterase with broad substrate specificity. Contributes to the inactivation of the neurotransmitter acetylcholine. Can degrade neurotoxic organophosphate esters.

Tocris Summary for BCHE Gene

  • Cholinesterases inactivate the neurotransmitter acetylcholine by catalyzing its hydrolysis to choline and acetic acid. Acetylcholinesterase (AChE) is found in erythroid cells and at neuronal synapses, whilst butyrylcholinesterase (BChE) is mostly expressed in the liver.

Post-translational modifications for BCHE Gene

  • N-glycosylated. No other PTM detected (PubMed:20946535). The major N-glycan structures are of the complex diantennary type with 1 and 2 N-acetylneuraminic acid molecules (Neu5Ac) making up approximately 33% and 47% of the total N-glycans, respectively. Only low amounts of fucosylated diantennary N-glycans are detected (approximately 2%). Triantennary N-glycans with or without fucose amount to approximately 13%, whereas 5% of the total N-glycans are of the oligomannosidic or hybrid type.
  • Glycosylation at Asn45, Asn85, Asn134, Asn269, Asn284, Asn369, Asn483, Asn509, Asn513, and Asn514
