OverviewNCBI Gene
This gene belongs to the TIMP gene family. The proteins encoded by this gene family are inhibitors of the matrix metalloproteinases, a group of peptidases involved in degradation of the extracellular matrix (ECM). Expression of this gene is induced in response to mitogenic stimulation and this netrin domain-containing protein is localized to the ECM. Mutations in this gene have been associated with the autosomal dominant disorder Sorsby's fundus dystrophy. [provided by RefSeq, Jul 2008]

Whether an antibody against TIMP3 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 TIMP3 as an antibody target. Whether an autoantibody or antibody against TIMP3 could matter depends on whether native TIMP3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
TIMP3 is annotated as secreted, so native TIMP3 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 TIMP3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
