Protein Structure
UniProt Annotation
Function Cytotoxin and helminthotoxin. Also induces non-cytolytic histamine release from human basophils. Involved in antiparasitic defense mechanisms and immune hypersensitivity reactions. The proform acts as a proteinase inhibitor, reducing the activity of PAPPA. {ECO:0000269PubMed:10913121}.
Subcellular Localization Bone marrow proteoglycan: Secreted. Note=The proform is secreted.Eosinophil granule major basic protein: Cytoplasmic vesicle, secretory vesicle. Note=The proform is secreted. The mature protein is found in the matrix of the eosinophil's large specific granule (crystalloid core).
Disease Associations
Tissue Specificity High levels of the proform in placenta and pregnancy serum; in placenta, localized to X cells of septa and anchoring villi. Lower levels in a variety of other tissues including kidney, myometrium, endometrium, ovaries, breast, prostate, bone marrow and colon. {ECO:0000269PubMed:10491647, ECO:0000269PubMed:7526035}.
