Technical Data
DMP1 (Dentin Matrix Acidic Phosphoprotein 1, DMP-1, Dentin Matrix Protein 1)
DMP1 is an extracellular matrix protein and a member of the small integrin binding ligand N-linked glycoprotein family. It is critical for proper mineralization of bone and dentin, and is present in diverse cells of bone and tooth tissues. DMP1 contains a large number of acidic domains, multiple phosphorylation sites, a functional arg-gly-asp cell attachment sequence, and a DNA binding domain. DMP1 may also have a dual function during osteoblast differentiation. In the nucleus of undifferentiated osteoblasts the 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.

Suitable for use in ELISA and Western Blot. Other applications not tested.
