Identification of amino acid residues of nerve growth factor important for neurite outgrowth in human dorsal root ganglion neurons.

ABSTRACT: Nerve growth factor (NGF) is an essential neurotrophic factor for the development and maintenance of the central and the peripheral nervous system. NGF deficiency in the basal forebrain precedes degeneration of basal forebrain cholinergic neurons in Alzheimer's disease, contributing to memory decline. NGF mediates neurotrophic support via its high-affinity receptor, the tropomyosin-related kinase A (TrkA) receptor, and mediates mitogenic and differentiation signals via the extracellular signal-regulated protein kinases 1 and 2 (ERK1/2). However, the molecular mechanisms underlying the different NGF/TrkA/ERK signalling pathways are far from clear. In this study, we have investigated the role of human NGF and three NGF mutants, R100E, W99A and K95A/Q96A, their ability to activate TrkA or ERK
