This protein, which is critical for proper mineralization of bone and dentin, is present in diverse cells of bone and tooth tissues. The protein contains a large number of acidic domains, multiple phosphorylation sites, a functional arg-gly-asp cell attachment sequence, and a DNA binding domain. In undifferentiated osteoblasts it is primarily a nuclear protein that regulates the expression of osteoblast-specific genes. During osteoblast maturation the protein becomes phosphorylated and is exported to the extracellular matrix, where it orchestrates mineralized matrix formation. Mutations in the gene are known to cause autosomal recessive hypophosphatemia, a disease that manifests as rickets and osteomalacia. The gene structure is conserved in mammals. Two transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Jul 2008]. * **UniProt Summary**: May have a dual function during osteoblast differentiation. In the nucleus of undifferentiated osteoblasts, unphosphorylated form acts as a transcriptional component for activation of osteoblast-specific genes like osteocalcin. During the osteoblast to osteocyte transition phase it is phosphorylated and exported into the extracellular matrix, where it regulates nucleation of hydroxyapatite. {ECO:0000269|PubMed:12615915}. |DMP1| |regulation of enamel mineralization| |regulation of tooth mineralization| |regulation of odontogenesis of dentin-containing tooth| |regulation of odontogenesis| |extracellular matrix binding| |biomineralization| |regulation of biomineralization| |biomineral tissue development| |regulation of biomineral tissue development| |positive regulation of cell-substrate adhesion| |integrin binding| |regulation of cell-substrate adhesion| |extracellular matrix| |regulation of animal organ morphogenesis| |ossification| |endoplasmic reticulum lumen| |extracellular matrix organization| |post-translational protein modification| |extracellular structure organization| |positive regulation of cell adhesion| |regulation of cell adhesion| |calcium ion binding| |regulation of anatomical structure morphogenesis| |tissue development| |extracellular region| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp232|Epothilone-D 0.004 to 0.006μM on day4 R05 exp232]]|-2.04| |[[:results:exp288|HMS-I2 10μM R06 exp288]]|-1.87| |[[:results:exp164|Q15 1 to 2μM on day4 R04 exp164]]|-1.8| |[[:results:exp298|Sucrose 20000μM R06 exp298]]|-1.77| |[[:results:exp449|Arsenic trioxide 60μM R08 exp449]]|-1.76| |[[:results:exp47|Lapatinib 5μM R01 exp47]]|-1.74| |[[:results:exp36|TRAIL 50ng/ml R00 exp36]]|-1.73| |[[:results:exp293|Myriocin 25μM R06 exp293]]|-1.72| |[[:results:exp294|Nutlin-3A 1.6μM R06 exp294]]|-1.72| No correlation found to any other genes in chemogenomics.
