Bombesin (BN) is a tetradecapepide (Pyro-ENR LGN QWA VGH LM-amide) that was originally isolated from frog skin. Several BN-related peptides have been isolated from amphibians and classified into three subfamilies: Bombesin, ranatensin and phyllolitorin based upon the last three C-terminal residues. Two BN-like peptides have been identified in mammals: NMB (neuromedin B) in the ranatensin family and GRP (gastrin-releasing peptide) in the BN-family. BN-family of G-protein coupled receptors include at least four receptor subtypes: The GRP-preferring receptors (GRP-R or bb2), the NMB-preferring receptors (NMB-R or bb1) and Bombesin receptor subtype 3 (BRS-3 or bb4). These receptors share ~50% amino acid homology and bind bombesin. However, BRS-3 has much lower affinity for BN than GRP-R and NMB-R. Mammalian BN-like peptides are widely distributed in the brain and gastrointestinal tract, where they modulate smooth-muscle contraction, exocrine and endocrine activities, metabolism and behavior. Most recently, BRS-3 deficient mice have been shown to develop mild obesity, associated with hypertension, and impairment of glucose metabolism, reduced metabolic rate, increased feeding efficiency and subsequent hyperphagia.
