OverviewNCBI Gene
This gene encodes a member of the S100 protein family which contains an EF-hand motif and binds calcium. The gene is located in a cluster of S100 genes on chromosome 1. Levels of the encoded protein have been found to be lower in cancerous tissue and associated with metastasis suggesting a tumor suppressor function (PMID: 19956863, 19351828).

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 S100A14 as an antibody target. Whether an autoantibody or antibody against S100A14 could matter depends on whether native S100A14 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
S100A14 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 S100A14 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
