DiseaseUniProt · ClinVar · IEDB · PubMed
Four sources answering four different questions about DDX27.
Disease | AutoantibodyPubMed
Conditions in which antibodies against DDX27 are reported. Each links to that disease's full target list.
Showing 0 of 1 — disease pages carrying at least 10 antigens.
ReferencesPubMed · IEDB
Publications for DDX27 from three distinct lines of evidence, kept separate because they answer different questions: whether antibodies are directed at the protein, whether a B-cell epitope has been mapped on it, and whether a T-cell epitope has. Each is labelled with its source.

Sources: PubMed — antigen-level antibody evidence from a custom retrieval. Records matching a controlled set of autoantibody terms (the MeSH descriptors Autoantibodies and Autoantigens, with title and abstract term variants) were obtained through NCBI E-utilities, and their titles and abstracts parsed for constructions that direct an antibody at a named protein rather than for co-occurrence. Captured names were resolved against UniProt nomenclature and each antigen adjudicated individually against the source text. Bibliographic records from PubMed and MeSH, U.S. National Library of Medicine; citation metrics from NIH iCite (Hutchins et al., PLoS Biology 2016). Titles link to PubMed; abstracts are not reproduced here. The NLM does not endorse this analysis.

Protein binding partners of DDX27 in the human serome: UniProt-annotated complex subunits plus reported interactors. Each links to its own Seroatlas record.
Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads DDX27 as an antibody target. Whether an autoantibody or antibody against DDX27 could matter depends on whether native DDX27 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
DDX27 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 DDX27 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
