Bombesin receptor

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 NMBR
• BB₂, previously known as Gastrin-releasing peptide receptor GRPR
• BB₃, previously known as Bombesin-like receptor 3 BRS3
