Neuromedin B

Neuromedin B (NMB) is a bombesin-related peptide in mammals. It was originally purified from pig spinal cord, and later shown to be present in human central nervous system and gastrointestinal tract. Neuromedin B (NMB) is a bombesin-related peptide in mammals. It was originally purified from pig spinal cord, and later shown to be present in human central nervous system and gastrointestinal tract. The sequence of the C-terminal decapeptide is highly conserved across mammalian species: GNLWATGHFM-(NH2); this decapeptide is sometimes noted as neuromedin B, but it is more accurately described as neuromedin B 23-32. The sequence of neuromedin B (in rat) is : TPFSWDLPEPRSRASKIRVHPRGNLWATGHFM-(NH2).
