Webp75NTR (p75 neurotrophin receptor) affects the binding affinity and specificity of Trk receptor activation by neurotrophins. The presence of p75NTR is especially important in increasing the binding affinity of NGF to TrkA. [3] Although the dissociation constants of p75NTR and TrkA are remarkably similar, their kinetics are quite different. [3]
