SUBCELLULAR LOCALIZATION	extracellular
	plasma membrane
text	localized to the Weibel-Palade bodies of vascular endothelial cells

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

CELLULAR PROCESS	cell life, antiapoptosis

protein	Osteoclast differentiation factor
	von Willebrand factor, vWF
	CTGF significantly bound to TNFRSF11B, which is a decoy receptor of TNFSF11

Susceptibility

to osteoporotic fracture (to hip fractures) to the progression of atherosclerosis and cardiovascular disease to periodontitis to coronary artery disease to sporadic Paget bone disease

Variant & Polymorphism SNP , other	A163-G and T245-G were significantly more common among patients with vertebral fractures
	950 TC/1181 GC and 950 CC/1181 CC associated to an increased risk of coronary artery disease
	TG haplotype of T950C and G1181C polymorphisms in the OPG gene may be useful genetic markers for the prediction of periodontitis (Park 2008)
	G1181 allele, encoding lysine at codon 3 predisposing to the development of sporadic Paget bone disease
	Lys3Asn polymorphism increases susceptibility to hip fractures among older white women

Candidate gene
Marker	expression of TNFRSF11A, TNFSF11 and TNFRSF11B may be used as diagnostic markers to identify patients at high risk for aggressive Prostate carcinoma 6)
Therapy target
	System Type Disorder Pubmed cancer reproductive prostate effective suppression of Prostate carcinoma cell migration by TNFRSF11B via the blockage of TNFSF11 activity represents a potential therapeutic strategy for interfering with prostate tumor metastasis and progression to bone

ANIMAL & CELL MODELS

	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
