Expression of Pleiotrophin as Separate Domains to Examine Glycosaminoglycan Binding Sites

Kuch, Nathaniel Jacob

Glycosaminoglycan (GAG) binding by the cytokine pleiotrophin (PTN) was examined by expressing both thrombospondin 1 type-1 repeat domains of PTN separately, as PTN-N and PTN-C. PTN-N contains residues 31-89, and PTN-C contains residues 90-146. Nuclear magnetic resonance (NMR) experiments were…

Glycosaminoglycan (GAG) binding by the cytokine pleiotrophin (PTN) was examined by expressing both thrombospondin 1 type-1 repeat domains of PTN separately, as PTN-N and PTN-C. PTN-N contains residues 31-89, and PTN-C contains residues 90-146. Nuclear magnetic resonance (NMR) experiments were conducted on both PTN-N and PTN-C to elucidate GAG binding regions.
