    basic FUNCTION
  • cell to cell signaling between stromal cells and osteoclast progenitor
  • can act as a soluble factor in the regulation of bone mass
  • specifically inhibits osteoclastogenesis
  • playing a role in the vascular system
  • involved in RANKL/RANK signaling
  • regulates dendritic cells survival, monocyte chemotaxis, and B cell development and function by ligating TNF family member receptor activator of NF-kappaB ligand (TNFSF11)
  • acts as an autocrine/paracrine growth factor for vascular smooth muscle cells, which might contribute to the progression of atherosclerotic lesions (Corallini 2009)
  • key factor linking bone formation to resorption during bone remodeling
  • expression of TNFRSF11B, TNFRSF11A and TNFSF11 genes exert a crucial role in the progression of Femoral head avascular necrosis (AVN), suggesting their roles in mediating bone homeostasis and potential effects on bone destruction

  • OPG-/- mice exhibit a decrease in total bone density characterized by severe trabecular and cortical bone porosity, marked thinning of the parietal bones of the skull, and a high incidence of fractures
  • OCIF/OPG knockout mice are viable and fertile but exhibit severe osteoporosis due to enhanced osteoclastogenesis, and marked bone loss accompanied by destruction of growth plate and lack of trabecular bone in their femurs
