LocalizationUniProt · AlphaFold · HPA

Whether an antibody against LRRC59 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Genetic constraint and essentialitygnomAD · DepMap

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads LRRC59 as an antibody target. Whether an autoantibody or antibody against LRRC59 could matter depends on whether native LRRC59 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

LRRC59 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 LRRC59 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
