DMP1 Antibody

Background:

Dentin matrix acidic phosphoprotein is an extracellularmatrix protein and a member of the small integrin binding ligandN-linked glycoprotein family. This protein, which is critical forproper mineralization of bone and dentin, is present in diversecells of bone and tooth tissues. The protein contains a largenumber of acidic domains, multiple phosphorylation sites, afunctional arg-gly-asp cell attachment sequence, and a DNA bindingdomain. In undifferentiated osteoblasts it is primarily a nuclearprotein that regulates the expression of osteoblast-specific genes.During osteoblast maturation the protein becomes phosphorylated andis exported to the extracellular matrix, where it orchestratesmineralized matrix formation. Mutations in the gene are known tocause autosomal recessive hypophosphatemia, a disease thatmanifests as rickets and osteomalacia. The gene structure isconserved in mammals. Two transcript variants encoding differentisoforms have been described for this gene.
