proNT-3 (the precursor form of neurotrophin-3) functions through p75NTR and sortilin and induces neuronal apoptosis. In contrast, mature NT-3 interacts with Trk receptors and selectively promotes the survival, growth and differentiation of neurons. Since axon retrograde transport is crucial for neurotrophin signaling, proNT-3 also has an important role in the mechanism of retrograde signaling.
proNT3 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 239 amino acids and having a molecular mass of 27.4kDa.
The proNT3 is purified by proprietary chromatographic techniques.
