NT-4 is a neurotrophic factor structurally related to β-NGF, BDNF, and NT-3.  These proteins belong to the cysteine-knot family of growth factors that assume stable dimeric structures.  NT-4 is expressed in the prostate, thymus, placenta, and skeletal muscle.  NT-4 can signal through the LNGFR and trkB receptors, and promotes the survival of peripheral sensory sympathetic neurons.  Recombinant Human NT-4 is a noncovalently linked homodimer of two 14.0 kDa polypeptide monomers (260 total amino acid residues).
