    basic FUNCTION
  • activating type I receptor kinase domain (ligand binding)
  • maintenance of vascular endothelium integrity
  • may play an important role in the pathogenesis of myelofibrosis in primary myelofibrosis and are apparently induced by cytokines such as TGFbeta-1
  • being a modulator of glucocorticoid signaling
  • contributing with ACVRL1 to growth inhibition of human pulmonary artery endothelial cells
  • plays a major role in early development, carcinogenesis, and vascular disease, particularly pulmonary arterial hypertension (PAH)
  • constitutively turned over through the lysosomal pathway by endogenous E3 ligases
  • not required for endochondral ossification in the limb where loss of BMPR2 may be compensated by BMP utilization of ACVR2A and ACVR2B
  • has tumor-suppressive function in mammary epithelia and microenvironment and that disruption can accelerate mammary carcinoma metastases
  • promotes pulmonary artery endothelial cell (PAEC) survival, proliferation, and migration
  • essential for postimplantation physiology and fertility
  • regulates SMAD1 in a biphasic manner, promoting SMAD1 signaling through its kinase domain but suppressing it through its cytoplasmic tail 9)
    text skeletal development
    signaling signal transduction
  • BMPR2 pathway mediate survival signaling in endothelial cells (EC), and thus the reduced activity will favor endothelial apoptosis, likely increasing the susceptibility to endothelial injury in response to various environmental triggers
  • constitutive lysosomal pathway regulating cell surface expression of BMPR2 and implicating the likely involvement of the mammalian E3 ligase, ITCH, in this process
  • a component
  • complexing with type I BMP receptors, BMPR1A, BMPR1B
    small molecule
  • ATP
  • protein
  • activating Smad proteins (MAPH) when ligands are bound to preformed-receptor complex
  • binding BMP2, BMP4, BMP7
  • activating alkaline phosphatase via MAP kinase BMP2 induces recruitment of receptors
  • BMP2 induced recruitment of receptors activating the p38 MAP kinases resulting in an increase of alkaline phosphatase
  • tenascin-C is induced by mutated BMP type II receptors in familial forms of pulmonary arterial hypertension
  • caveolin-1 is an important regulator of downstream signaling and membrane targeting of BMPR2 in vascular smooth muscle cells
  • interacting with K5, the viral lytic gene, E3 ubiquitin ligase (K5 targets the membrane-proximal lysine of BMPR2, Lys-180)
  • requirement for BMPR2 in tumors to prevent CCL9 secretion and the recruitment of myeloid cells
  • BMPR2 ligands, BMP2 and BMP4, stimulate NOS3 phosphorylation at a critical regulatory site
  • PLXNA2 was associated with both type 1 and 2 BMP receptors (BMPR1A, BMPR2), and BMP2 increased the interaction between PLXNA2 and type 1 receptors
  • NIPA1 interacts with the type II BMP receptor (BMPR2) and promotes its degradation through endocytosis and lysosomal degradation
  • ACVR2A and and BMPR2 physically interact, and each also interacts with endoglin
  • SMYD2 may promote BMP signaling by directly methylating BMPR2, which, in turn, stimulates BMPR2 kinase activity and activation of the BMP pathway
