OverviewNCBI Gene
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]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads BCHE as an antibody target. Whether an autoantibody or antibody against BCHE could matter depends on whether native BCHE is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
BCHE is annotated as secreted, so native BCHE circulates and is directly accessible to antibodies. Secreted and cell-surface proteins are the autoantibody targets most likely to act like drugs, blocking or depleting the native protein.
Annotation status
The present source text does not explicitly label BCHE as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
