General description
Periostin (POSTN) gene with 23 exons spanning 36 kb is mapped to chromosome 13q13.3. The gene codes for periostin, a matricellular protein that belongs to the family of non-structural matrix proteins. Periostin structure contains a signal peptide, four fasciclin-like domains (FAS1) with vitamin K-dependent γ-carboxyglutamic acid (Gla) residues, and hydrophilic C-terminal region with the heparin-binding site. The protein is mainly expressed in the periosteum, periodontal ligament, heart valves, and tendons. The antibody detects endogenous level of total periostin protein.
Immunogen
Peptide sequence around aa. 125-129 ( R-E-E-I-E), according to the protein NP_006466.2
Application
Anti-POSTN antibody produced in rabbit has been used in western blot.
Biochem/physiol Actions
Periostin (POSTN) facilitates extracellular matrix structure and organization. It acts as a collagen chaperone and regulates type I collagen fibrillogenesis. POSTN is implicated in early stages of bone formation, tissue repair, and cell recruitment and adhesion. This protein is essential for cancer stem cell maintenance and metastasis. Increased expression of POSTN has been observed in various types of cancers including prostate, breast, lung, pancreatic, ovarian, and colorectal cancer. Hence, the postn levels can be used as a prognostic biomarker for these cancers.

Periostin (gene Postn) is a secreted extracellular matrix protein involved in cell recruitment and adhesion and plays an important role in odontogenesis. In bone, periostin is preferentially expressed in the periosteum, but its functional significance remains unclear. We investigated Postn(-/-)
