Subcellular Location
[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).
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 co
