OverviewNCBI Gene

Kindlins are a small family of proteins that mediate protein-protein interactions involved in integrin activation and thereby have a role in cell adhesion, migration, differentiation, and proliferation. The protein encoded by this gene has a key role in the regulation of hemostasis and thrombosis. This protein may also help maintain the membrane skeleton of erythrocytes. Mutations in this gene cause the autosomal recessive leukocyte adhesion deficiency syndrome-III (LAD-III). Alternative splicing results in multiple transcript variants encoding distinct isoforms.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against FERMT3 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 FERMT3 as an antibody target. Whether an autoantibody or antibody against FERMT3 could matter depends on whether native FERMT3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

FERMT3 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 FERMT3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
