OverviewNCBI Gene
This gene encodes a member of the AMP deaminase gene family. The encoded protein is a highly regulated enzyme that catalyzes the hydrolytic deamination of adenosine monophosphate to inosine monophosphate, a branch point in the adenylate catabolic pathway. This gene encodes the erythrocyte (E) isoforms, whereas other family members encode isoforms that predominate in muscle (M) and liver (L) cells. Mutations in this gene lead to the clinically asymptomatic, autosomal recessive condition erythrocyte AMP deaminase deficiency. Alternatively spliced transcript variants encoding different isoforms of this gene have been described. [provided by RefSeq, Jul 2008]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads AMPD3 as an antibody target. Whether an autoantibody or antibody against AMPD3 could matter depends on whether native AMPD3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
AMPD3 is annotated as secreted, so native AMPD3 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 AMPD3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
