General description

Bantag-1 is a peptide-antagonist.[1] It is soluble in aqueous solutions.[2]

Biochem/physiol Actions

Bantag-1 is a very specific, high affinity antagonist of the orphan GPCR Bombesin receptor subtype-3 (BRS-3).
Bantag-1 is a very specific, high affinity antagonist of the orphan GPCR Bombesin receptor subtype-3 (BRS-3). The binding affinity of Bantag-1 in BRS-3 expressing cells is 1.3 nM.

Bombesin receptor subtype 3 (BRS-3) is a G protein coupled receptor whose natural ligand is unknown. We developed potent, selective agonist (Bag-1, Bag-2) and antagonist (Bantag-1) ligands to explore BRS-3 function. BRS-3-binding sites were identified in the hypothalamus, caudal brainstem
