OverviewNCBI Gene

This gene encodes a member of the ADAM (a disintegrin and metalloprotease domain) family. Members of this family are membrane-anchored proteins structurally related to snake venom disintegrins, and have been implicated in a variety of biological processes involving cell-cell and cell-matrix interactions, including fertilization, muscle development, and neurogenesis. The protein encoded by this gene interacts with SH3 domain-containing proteins, binds mitotic arrest deficient 2 beta protein, and is also involved in TPA-induced ectodomain shedding of membrane-anchored heparin-binding EGF-like growth factor. Several alternatively spliced transcript variants have been identified for this gene. [provided by RefSeq, Jul 2010]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against ADAM9 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 ADAM9 as an antibody target. Whether an autoantibody or antibody against ADAM9 could matter depends on whether native ADAM9 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

ADAM9 is annotated at the cell surface, where native ADAM9 is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.

Annotation status

The present source text does not explicitly label ADAM9 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
