Target Background

Nerve growth factor β (BNGF) is a neurotrophin essential for the development and functional maintenance of neurons in the central (cholinergic) and peripheral nervous system. It is translated as a precursor pro-protein which undergoes cleavage to produce a biologically active fragment, which is then homodimerized and secreted. The main receptor for BNGF is tyrosine kinase receptor A (TRKA). Mutations in the BNGF gene are associated with loss of pain perception (hereditary, sensory and autonomic neuropathy, type 5 (HSAN5)), mental retardation and immune deficiency.
