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.
It is a secreted protein that binds heparin and functions as a ligand for αVβ3 and αVβ5 integrins.
In preosteoblasts, Periostin 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 upregulated in epithelial ovarian tumors and overexpressed in breast cancer.
Expression of Periostin is increased by BMP2 and TGF-β1.
The protein contains a signal sequence, a cysteine-rich domain, a fourfold repeated domain homologous to insect fasciclin, and a C-terminal domain.
