研究背景
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 (By similarity). Promotes dental pulp stem cell proliferation and differentiation.
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.

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.
Interacts (via the ASARM motif) with PHEX; the interaction is zinc-dependent.
The acidic serine aspartate-rich MEPE-associated (ASARM) motif is sufficient when phosphorylated to inhibit bone mineralization by osteoblasts and cartilage mineralization by chondrocytes by binding hydroxyapatite crystals during the mineralization stage (PubMed:15664000, PubMed:18162525, PubMed:18597632, PubMed:19998030, PubMed:22766095). It can also inhibit dentin mineralization (PubMed:20581062).
The dentonin region is sufficient to promote dental pulp stem cell proliferation (PubMed:15153459). It can also stimulate bone formation, osteoblast differentiation, and activate integrin signaling pathways (PubMed:15040834).
Belongs to the PF07175/osteoregulin family.
