Bombesin receptor
Encyclopedia
The bombesin receptors are a group of G-protein coupled receptors which bind bombesin
.
Three bombesin receptors are currently known:
BB1, previously known as Neuromedin B receptor
BB2, previously known as Gastrin-releasing peptide receptor
BB3, previously known as Bombesin-like receptor 3
Bombesin
Bombesin is a 14-amino acid peptide originally isolated from the skin of a frog. It has two known homologs in mammals called neuromedin B and gastrin-releasing peptide. It stimulates gastrin release from G cells. It activates three different G-protein-coupled receptors known as BBR1, -2, and -3. It...
