Ngfb, Recombinant, Mouse (Beta-nerve Growth Factor, Beta-NGF, Ngf)

Beta-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. Beta-NGF is a potent neurotrophic factor that signals through its receptor Beta-NGFR, and plays a crucial role in the development and preservation of the sensory and sympathetic nervous systems. Beta-NGF also acts as a growth and differentiation factor for B lymphocytes and enhances B-cell survival. The functional form of murine Beta-NGF is a noncovalently disulfide-linked homodimer, of two 13.4kD polypeptide monomers (240aa). The three disulfide bonds are required for biological activity.
