    basic FUNCTION
  • required for signal transduction
  • downstream mediator of Indian Hedgehog
  • regulator of chondrocyte differentiation
  • receptor for BMP2, BMP4, and AMH (inducing regression of Muller ducts)
  • activating Smad proteins (MADH)
  • having a overlapping function with BMPR1B in early chondrogenesis
  • may interact with SF3B4 and modulate the activity of a developmentally relevant splicing factor
  • playing age-dependent roles for BMP signaling in osteoblasts for bone remodeling
  • playing a crucial role in vessel remodeling, vessel integrity and endocardial cushion formation during the development of the circulation system
  • BMPR1A and ACVR1, activate multiple signaling pathways to regulate lens formation
  • in osteoblasts negatively regulates endogenous bone mass and Wnt/beta-catenin signaling and this regulation may be mediated by the activities of SOST and DKK1
  • its signaling plays critical roles in palatal shelf growth and palatal bone formation
  • CELLULAR PROCESS cell life, proliferation/growth
    text colonic epithelial cells growth control
    signaling signal transduction
    SMAD pathway
    a component
  • complexing with BMPR2
    small molecule
  • binding to members of the TGF beta superfamily
  • binding to BMP2 and BMP4
  • GIPC1, ACVR1, BMPR1A, and TGFBR1 are signaling components required for TGFBR3-mediated endothelial cell epithelial-mesenchymal transformation
  • PLXNA2 was associated with both type 1 and 2 BMP receptors, and BMP2 increased the interaction between PLXNA2 and type 1 receptors
  • FGFR3 facilitates BMPR1A to degradation through SMURF1-mediated ubiquitination pathway
  • ACVR1 is required for chondrocyte proliferation and differentiation, particularly in craniofacial and axial elements, but exerts coordinated functions with both BMPR1A and BMPR1B throughout the developing endochondral skeleton
  • STK11 negatively regulates BMPR1A, BMPR1B signaling
