背景介绍 Neurotrophins are well-known retrograde signaling molecules that regulate differentiation and cell survival in many central and peripheral neurons. Neurotrophin-4 (NT-4) is the most recently discovered neurotrophic factor in mammals and, functionally, the least well understood. Little is known about the role of NT-4 in supporting the survival of identified classes of sensory neurons. Mice lacking NT4 (NT4/) exhibit a loss of ~50% of the neurons in the nodose-petrosal and geniculate ganglia but no apparent loss of neurons in the dorsal root ganglia. 产品介绍 Recombinant NT-4 is a disulfide-linked homodimer protein consisting of two 131 amino acid residues, and migrates as an approximately 29 kDa protein under non-reducing and as 14 kDa under reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human Neurotrophin-4 mature chain was expressed in E. coli.
