During cleavage of proteoglycans, may release soluble FGF-glycosaminoglycan complexes that promote the intensity and range of FGF signals in the extracellular space. Regulates the access to insulin-like growth factors (IGFs) by cleaving IGF-binding proteins.

Widely expressed, with strongest expression in placenta (at protein level). Secreted by synovial fibroblasts. Up- regulated in osteoarthritis and rheumatoid arthritis synovial fluids and cartilage as compared with non-arthritic (at protein level).
Cell membrane. Secreted. Cytoplasm, cytosol. Predominantly secreted (PubMed:15208355). Also found associated with the plasma membrane (PubMed:21297635).
