CC       at 10 days post-fracture in late hypertrophic chondrocytes. At 14 days
CC       post-fracture, expression is detected in osteocytes, osteoblasts, and
CC       hypertrophic chondrocytes. By 28 days post-fracture, expression was
CC       highest in osteocytes and lower in osteoblasts (PubMed:15221418). Down-
CC       regulated by 1-alpha-25-dihydroxyvitamin D3 (calcitriol)

CC   -!- DOMAIN: The acidic serine aspartate-rich MEPE-associated (ASARM) motif
CC       is sufficient when phosphorylated to inhibit bone mineralization by
CC       osteoblasts and cartilage mineralization by chondrocytes by binding
CC       hydroxyapatite crystals during the mineralization stage
CC       (PubMed:15843468, PubMed:22766095, PubMed:26051469). It can also

CC       ECO:0000269|PubMed:22766095, ECO:0000269|PubMed:26051469}.
CC   -!- DOMAIN: The dentonin region is sufficient to promote dental pulp stem
CC       cell proliferation. It can also stimulate bone formation, osteoblast
CC       differentiation, and activate integrin signaling pathways.
CC       {ECO:0000250|UniProtKB:Q9NQ76}.
CC   -!- PTM: Phosphorylated on serine residues in the ASARM motif; the
CC       phosphorylation is important for the inhibition of bone mineralization.
CC       {ECO:0000269|PubMed:15843468, ECO:0000269|PubMed:18597632,
CC       ECO:0000269|PubMed:22766095}.
CC   -!- PTM: Cleaved by CTSB/cathepsin B; the cleavage is blocked by
CC       metalloprotease PHEX. {ECO:0000250|UniProtKB:Q9NQ76}.
CC   -!- DISRUPTION PHENOTYPE: Mutant mice exhibit increased cancellous bone
CC       mass and no loss of trabecular bone characteristics (PubMed:12421822,
CC       PubMed:26051469). They also exhibit decreased biomechanical strength in
CC       their bones and increased skeletal mineralization (PubMed:15843468). In
CC       craniofacial complex development, mutant mice also exhibit
CC       hypermineralization in predentin, dentin and enamel of teeth and
CC       decreased expression of AMBN, ENAM, IBSP, DMP1, DSPP and SPP1
CC       (PubMed:26927967). Mutant mice also exhibit hyperphostatemia and
CC       increased expression of SLC34A1/NPT2a, SLC34A3/NPT2c and VEGF in the
CC       kidney (PubMed:26051469). Hyperuricemia and reduced fractional
CC       excretion of uric acid was also exhibited (PubMed:26051469). As mutant
CC       mice age, bone mineral density and content is increased
CC       (PubMed:26051469). {ECO:0000269|PubMed:12421822,
