Pleiotrophin is a secreted growth factor that signals through cell surface proteoglycan and non-proteoglycan receptors to influence a variety of cellular processes. It binds to chondroitin sulfate (CS) groups, regulates proliferation, survival and differentiation, and inhibits long-term synaptic potentiation of neurons. Pleiotrophin Protein, Human is the recombinant human-derived Pleiotrophin protein, expressed by E. coli , with tag free. The total length of Pleiotrophin Protein, Human is 136 a.a., with molecular weight of ~15.3 kDa.
