Human BDNF (AF)

BDNF belongs to the NGF family of neurotrophic growth factors, supporting neuron growth and survival. It binds to a low-affinity cell surface receptor, LNGFR, shared with other neurotrophins like NGF, NT-3, and NT-4. However, BDNF primarily exerts its neurotrophic effects through the high-affinity receptor gp145/trkB. Structurally, BDNF is part of a 247 amino acid polypeptide precursor, featuring an 18 amino acid signal sequence and a 110 amino acid propeptide. Recombinant Human/Murine/Rat BDNF exists as a 27.0 kDa homodimer comprising two 120 amino acid subunits held together by robust non-covalent interactions.
