Description

Nerve growth factor (NGF or beta-NGF) is a vertebrate protein that stimulates division and differentiation of sympathetic and embryonic sensory neurons [1, 2]. NGF is a protein of about 120 residues that is cleaved from a larger precursor molecule. It contains six cysteines all involved in intrachain disulfide bonds. A schematic representation of the structure of NGF is shown below: +------------------------+ | | | ******* | xxxxxxCxxxxxxxxxxxxxxxxxxxxxCxxxxCxxxxxCxxxxxxxxxxxxxCxCxxxx | | | | +--------------------------|-----+ | +---------------------+ 'C': conserved cysteine involved in a disulfide bond.

to be structurally and functionally related to NGF, these are: - Brain-derived neurotrophic factor (BDNF), a protein that promotes the survival of neuronal populations all located either in the central nervous system or directly connected to it. - Neurotrophin-3 (NT-3), a protein that seems to promote the survival of visceral and proprioceptive sensory neurons. - Neurotrophins-4/5 (NT-4/5), which elicit neurite outgrowth from explanted dorsal root ganglia and could play a role in oogenesis and/or early embryogenesis. - Neurotrophin-6. - Neurotrophin-7 from zebrafish. The pattern we have developed for the NGF family spans the central region of these proteins and include two of the six cysteines involved in disulfide bonds.
