    A cDNA encoding a novel human neurotrophic factor (designated nerve growth factor-2; NGF-2) was cloned from a human glioma cDNA library using a synthetic DNA corresponding to human nerve growth factor (NGF). The cloned cDNA encodes a polypeptide composed of 257 amino acid residues including a prepro-sequence of 138 residues and a mature region of 119 residues. The amino acid sequence of human NGF-2 exhibits 58% similarity with that of human NGF. Conditioned medium of COS-7 cells transfected with an expression plasmid for human NGF-2 cDNA supported the survival of sensory neurons isolated from dorsal root ganglia of embryonic chicks. A 1.5 kb of NGF-2 mRNA can be detected from an early development stage in rat brain, by Northern blotting analysis.
