OverviewNCBI Gene
Prostaglandin-D synthase is a sigma class glutathione-S-transferase family member. The enzyme catalyzes the conversion of PGH2 to PGD2 and plays a role in the production of prostanoids in the immune system and mast cells. The presence of this enzyme can be used to identify the differentiation stage of human megakaryocytes. [provided by RefSeq, Jul 2008]

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

DiseaseUniProt · ClinVar · IEDB · PubMed
Four sources answering four different questions about HPGDS.
Disease | AutoantibodyPubMed
Conditions in which antibodies against HPGDS are reported. Each links to that disease's full target list.
ReferencesPubMed · IEDB
Publications for HPGDS 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.

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