Target Information
Periostin (PN), also known as osteoblast-specific factor 2 (OSF-2), is a disulfide-linked protein originally isolated as an osteoblast-specific factor.
Periostin is a secreted protein that binds heparin and functions as a ligand for α(V)β(3) and α(V)β(5) integrins. In preosteoblasts, it acts as a cell adhesion molecule and plays a role in osteoblast recruitment, spreading, and attachment.
Periostin is mainly detected in the lower gastrointestinal tract, aorta, stomach, placenta, uterus, and breast tissues but is up-regulated in epithelial ovarian tumors and overexpressed in breast cancer.
Expression of Periostin is increased by bone morphogenetic protein (BMP2) and transforming growth factor beta 1 (TGF-β1). It contains a typical signal sequence, a cysteine-rich domain, four fasciclin-like repeated domains, and a C-terminal domain.
