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 C16orf87 as an antibody target. Whether an autoantibody or antibody against C16orf87 could matter depends on whether native C16orf87 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

C16orf87 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 C16orf87 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
