一般描述
Pleiotrophin (PTN) is a multifunctional growth factor. The protein coded by the PTN gene is a member of the heparin-binding cytokines family. This gene is located on human chromosome 7. Pleiotrophin is also known as heparin-binding brain mitogen (HBBM), heparin-binding growth factor-8 (HBGF-8), heparin-binding growth-associated molecule (HB-GAM) and osteoblast-specific factor (OSF-1). This gene is highly expressed in brain, uterus, gut, muscle, lung and skin. Pleiotrophin mRNA is expressed in osteoblasts, chondrocytes, tumor cells, fibroblasts, astrocytes and Schwann cells.
应用
PTN is active in growth and development, and has mitogenic and neurite outgrowth activity. The gene for pleiotrophin is highly expressed in brain, uterus, gut, muscle, lung, and skin tissues
生化/生理作用
Pleiotrophin participates in growth and development. Pleiotrophin is mitogenic and displays neurite outgrowth activity. It stimulates tumor angiogenesis. There is extraordinary conservation between the amino acid sequences of bovine, human, and rat pleiotrophin.

Pleiotrophin/heparin-binding growth-associated molecule (HB-GAM) is a specific ligand of protein tyrosine phosphatase zeta (PTPzeta)/receptor-like protein tyrosine phosphatase beta (RPTPbeta) expressed in the brain as a chondroitin sulfate proteoglycan. Pleiotrophin and PTPzeta isoforms are localized along the radial glial fibers, a
