Gene Information

human ... POSTN(10631)

General description

Periostin (POSTN) is also known as osteoblast-specific factor-2. It is a 90 kDa protein expressed in the extracellular matrix and bones. POSTN is an adhesive glycoprotein. The gene encoding this protein is localized on human chromosome 13q13.3.

Immunogen

human Periostin recombinant protein. The human protein shares 87% homology with the mouse protein.

Application

Monoclonal Anti-Periostin antibody produced in mouse has been used to develop a periostin imaging PET probe.

Biochem/physiol Actions

Periostin (POSTN) has a role in the differentiation and cell adhesion of osteogenic cells. It functions as a biomarker of T-helper cells type 2-mediated inflammatory diseases. The protein has been associated with various cancers. POSTN is involved in epithelial-mesenchymal transition and extracellular matrix degradation.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
