Metabolite Identification
Common NameNeuromedin B (1-3)
DescriptionNMB acts by binding to its high affinity cell surface receptor, neuromedin B receptor (NMBR). This receptor is a G protein-coupled receptor with seven transmembrane spanning regions, hence the receptor is also denoted as a 7 transmembrane receptor (7-TMR). Upon binding several intracellular signaling pathways are triggered (see Figure 2). 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. This structure shows the 1-3 fragment of neuromedin B.
