ProNGF functions preferentially via the complex of pan-neurotrophin receptor p75 (p75NTR) and vps10p domain-containing receptor sortilin inducing neuronal apoptosis and contributing to age- and disease-related neurodegeneration.\u003c\/p\u003e\n\n\u003cp\u003eActivity: Measured in a cell proliferation assay using TF‑1 human erythroleukemic cells.
