Human Pleiotrophin (PTN) also called HARP (Heparin affin regulatory peptide) is a new member of the heparin-binding neurotrophic factor family. PTN (Pleiotrophin) and MK (Midkine) are structural homologs, and are highly conserved among species. PTN plays an important role in development processess and promotion of neurite extension. Recombinant PTN is a 13.4 kD protein, comprising of 136 amino acid residues.
