Tissue Specificity | Detected in urine (at protein level). Expressed by osteoblasts. Expressed by stem cells in dental pulp. Expressed by mesenchymal cells in dental papilla and dental pulp. Expressed in teeth, specifically in decidious dentin. Expressed in ondotoblasts. Expressed in salivary glands. Secreted from oncogenic hypophosphatemic tumors. |
Post Translational Modifications | Phosphorylated on serine residues in the ASARM motif (in vitro) by FAM20C.the phosphorylation is important for the inhibition of bone mineralization. Cleaved by CTSB/cathepsin B.the cleavage is blocked by metalloprotease PHEX. |
Function | Promotes renal phosphate excretion and inhibits intestinal phosphate absorption. Promotes bone mineralization by osteoblasts and cartilage mineralization by chondrocytes. Regulates the mineralization of the extracellular matrix of the craniofacial complex, such as teeth, bone and cartilage. Promotes dental pulp stem cell proliferation and differentiation. |
