詳述

β-NGF is a neurotrophic factor structurally related to BDNF, NT-3 and NT-4.? These proteins belong to the cysteine-knot family of growth factors that assume stable dimeric structures.? β-NGF is a potent neurotrophic factor that signals through its receptor β-NGFR, and plays a crucial role in the development and preservation of the sensory and sympathetic nervous systems.? β-NGF also acts as a growth and differentiation factor for B lymphocytes, and enhances B-cell survival.? The functional form of Recombinant Human β-NGF is a non-covalently-linked homodimer of two 13.5 kDa, polypeptide monomers that each contain 120 amino acids and three disulfide bonds, which are required for biological activity.
