Background

Nerve growth factor (NGF) is a polypeptide involved in the regulation of growth and differentiation of sympathetic and some sensory neurons, and is composed by 3 types of subunits (alpha, beta and gamma) that specifically interact to form a 7S, 130 kDa molecular weight complex. The beta-NGF subunit is a secreted protein that forms a homodimer before being incorporated into the NGF complex. The human and mouse sequences are very similar and mutations in this gene have been associated with hereditary sensory and autonomic neuropathy, type 5 (HSAN5). Deregulation of its expression has been associated with allergic rhinitis.
