OverviewNCBI Gene
Transglutaminases (TGM; EC 2.3.2.13) are a family of structurally and functionally related enzymes that stabilize protein assemblies through the formation of gamma-glutamyl-epsilon lysine crosslinks. For additional background information on transglutaminases, see TGM1 (MIM 190195).[supplied by OMIM, Jul 2002]

Whether an antibody against TGM7 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 TGM7 as an antibody target. Whether an autoantibody or antibody against TGM7 could matter depends on whether native TGM7 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
TGM7 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 TGM7 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
