Neuroglycan C (NGC) is a transmembrane-type chondroitin sulfate proteoglycan that promotes neurite outgrowth. To identify the ligand of NGC, we applied a detergent-solubilized membrane fraction of fetal rat brains to an NGC-immobilized affinity column. Several proteins were eluted from the column including an 18 kDa-band protein recognized by an anti-pleiotrophin antibody. The binding of pleiotrophin (PTN) to NGC was confirmed by a quartz crystal microbalance method and had a Kd of 8.7 nM. PTN bound to the acidic amino acid cluster of the NGC extracellular domain. In addition, PTN bound to both chondroitin sulfate-bearing NGC and chondroitinase-treated NGC prepared from the neonatal rat brain. These results suggest that NGC interacts with PTN.
