The neuromedin B receptor (NMBR), now known as BB₁ ^[4] is a G protein-coupled receptor whose endogenous ligand is neuromedin B.^[5] In humans, this protein is encoded by the NMBR gene.

Neuromedin B receptor binds neuromedin B, a potent mitogen and growth factor for normal and neoplastic lung and for gastrointestinal epithelial tissue.^[6]
