  • Function
    On ligand binding, forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators. Receptor for BMP7/OP-1 and GDF5.
  • Involvement in disease
    Defects in BMPR1B are the cause of acromesomelic chondrodysplasia with genital anomalies (AMDGA) [MIM:609441]. Acromesomelic chondrodysplasias are rare hereditary skeletal disorders characterized by short stature, very short limbs, and hand/foot malformations. The severity of limb abnormalities increases from proximal to distal with profoundly affected hands and feet showing brachydactyly and/or rudimentary fingers (knob-like fingers).
    Defects in BMPR1B are a cause of brachydactyly type A2 (BDA2) [MIM:112600]. Brachydactylies (BDs) are a group of inherited malformations characterized by shortening of the digits due to abnormal development of the phalanges and/or the metacarpals. They have been classified on an anatomic and genetic basis into five groups, A to E, including three subgroups (A1 to A3) that usually manifest as autosomal dominant traits. BDA2 was described first in a large Norwegian kindred. BDA2 is caused by mutations in BMPR1B gene and studies demonstrate that these mutations function as dominant negatives in vitro and in vivo.

  • ab78417 at 1/200 dilution staining BMPR1B in human placental tissue section by Immunohistochemistry (Formalin/PFA fixed paraffin-embedded sections).

  • All lanes : Anti-BMPR1B antibody [MM0055-3E12] (ab78417) at 1 µg/ml

    Lane 1 : Human bone tumor tissue lysate - total protein (ab29359)
    Lane 2 : WI38 (Human lung fibroblast cell line) Whole Cell Lysate

    Lysates/proteins at 10 µg per lane.

    All lanes : Goat Anti-Mouse IgG H&L (HRP) preadsorbed (ab97040) at 1/5000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 57 kDa
    Observed band size: 57 kDa
    Additional bands at: 30 kDa, 37 kDa, 50 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 30 seconds

    The band observed at 53 kDa could potentially be a cleaved form of BMPR1B due to presence of a 13 amino acid signal peptide.
