Bone morphogenetic protein receptor

Bone morphogenetic protein receptors are serine-threonine kinase receptors. Transforming growth factor beta family proteins bind to these receptors.[1] There are four bone morphogenetic protein receptors:[2]

  • Bone morphogenetic protein receptor, type 1:
    • ACVR1
    • BMPR1A
    • BMPR1B
  • Bone morphogenetic protein receptor, type 2
TKL Ser/Thr protein kinase family

Structure

Both type 1 and 2 bone morphogenetic protein receptors have a single transmembrane segment. Additionally, both types have a cysteine-rich extracellular domain and a cytoplasmic serine threonine kinase domain.[3] Type 1 contains a glycine-serine-rich domain to be phosphorylated by type 2 kinase domain, initiating the signaling transduction pathway of the SMAD signaling cascade.[3] The wrist epitope motif on BMP-2 has a high-affinity binding site for BMPR-IA. The knuckle epitope motif on BMP-2 has a low-affinity binding site for BMPR-II.[4]
