OverviewNCBI Gene

This gene encodes one of four critical components of the glycine cleavage system. Mutations in this gene have been associated with glycine encephalopathy. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against AMT can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads AMT as an antibody target. Whether an autoantibody or antibody against AMT could matter depends on whether native AMT is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

AMT is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

The present source text does not explicitly label AMT as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
