Role in Disease

  • Prostate Cancer: Reduced BMPR1B expression correlates with prostate cancer progression, suggesting its role as a tumor suppressor .

Signaling Mechanisms

BMPR1B forms heteromeric complexes with type II receptors (e.g., BMPR2) to activate SMAD transcription factors. Key interactions include:

  • Ligands: BMP7, GDF5 .

  • Downstream pathways: SMAD1/5/8 phosphorylation, regulating gene expression in osteogenesis .

Target Background

Function
Upon ligand binding, BMPR1B forms a receptor complex composed of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors, which subsequently autophosphorylate and bind to activate SMAD transcriptional regulators. BMPR1B acts as a receptor for BMP7/OP-1 and GDF5, positively regulating chondrocyte differentiation through its interaction with GDF5.
