Periostin is a 90-kDa matricellular protein that consists of a typical signal sequence, followed by a cysteine-rich region, an EMI domain (protein-protein interactions), four tandem fasciclin-like domains that are respons

ical processes such as cell proliferation, cell invasion and angiogenesis. Periostin expression is increased by both transforming growth factor β1 (TGF-β1) and bone morphogenetic protein 2 (BMP-2). Changes in periostin expression are commonly detected in various cancers and pre-cancerous conditions, and periostin may be involved in regulating cancer cell activities that contribute to tum
