LocalizationUniProt · AlphaFold · HPA

Whether an antibody against CCDC124 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 CCDC124 as an antibody target. Whether an autoantibody or antibody against CCDC124 could matter depends on whether native CCDC124 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

CCDC124 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 CCDC124 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
