Description générale

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.

Application

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

Actions biochimiques/physiologiques

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.

Forme physique

Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline.

Remarque sur l'analyse

The activity is measured in culture by the ability to enhance neurite outgrowth of cerebral cortical neurons from rat embryos.
