Bombesin receptors are activated by the endogenous ligands gastrin-releasing peptide (GRP), neuromedin B (NMB) and GRP18-27 (neuromedin C). Three subtypes of bombesin receptor are known: BB 1, BB 2 and an orphan receptor (bb 3).
Bombesin receptors are activated by the endogenous ligands gastrin-releasing peptide (GRP), neuromedin B (NMB) and GRP18-27 (neuromedin C). There are three subtypes of the bombesin receptor. BB 1 was previously known as the NMB receptor while BB 2 was previously known as the GRP receptor. BB 3 is designated an orphan receptor, however it has been shown to respond to NMB peptides, albeit at a lower potentcy than BB 1.
The receptors are G q/11-coupled and are involved in the regulation of many biological functions including sensory transmission, thermoregulation, feeding and pituitary, gastric and pancreatic secretion. They may also be involved in tissue development, proliferation and differentiation.
