MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is a member of the TNF-receptor superfamily. This protein is an osteoblast-secreted decoy receptor that functions as a negative regulator of bone resorption. This protein specifically binds to its ligand, osteoprotegerin ligand, both of which are key extracellular regulators of osteoclast development. Studies of the mouse counterpart also suggest that this protein and its ligand play a role in lymph-node organogenesis and vascular calcification. Alternatively spliced transcript variants of this gene have been reported, but their full length nature has not been determined. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygote null mice have abnormal bone remodeling that results in severe osteoperosis with increased risk of fractures and growth retardation. Progressive hearing loss also results due to abnormal remodeling of the otic capsule. [provided by MGI curators]

Protein Function and Prediction

Tumor necrosis factor receptor superfamily, member 11b [Tnfrsf11b; alternatively, osteoprotegerin (OPG) or osteoclastogenesis inhibitory factor (OCIF)], is a secreted protein that regulates bone resorption (1;2). It was determined that OPG regulates bone mass, osteoclast differentiation, inhibits the activation of mature osteoclasts, and stimulates osteoclast apoptosis (1).
Background

Mutations in TNFRSF11B cause juvenile Paget disease (OMIM: #239000), an osteopathic disorder that is characterized by rapidly remodeling woven bone, osteopenia, fractures, and progressive skeletal deformity [(3-5) and OMIM: *602643)].

Tnfrsf11btm1Eac/tm1Eac; MGI:2179712

involves: 129S4/SvJaeSor

These mice exhibit fractured diaphyses of long bones often seen in older mice, increased outer diameter of long bones (6).  These mice also have defective pro-B cell to pre-B cell transition, increased proliferative response to IL-7, increased number of peripheral B cells, and enhanced ability to stimulate T-cell proliferation (6).

Tnfrsf11btm1Khs/tm1Khs; MGI:2181227

B6.129P2-Tnfrsf11btm1Khs

This model has abnormal inner ear morphology and homozygotes display abnormal bone remodeling within the otic capsule with multiple foci showing osteoclastic bone resorption and formation of new bone, not observed in C57BL/6 control mice (7).  These mice also have decreased brainstem auditory evoked potential and increased susceptibility to age-related hearing loss (7).

Tnfrsf11btm1Khs/tm1Khs; MGI:2181227

involves: 129P2/OlaHsd * C57BL/6

This model exhibits partial postnatal lethality and postnatal growth retardation (8)  These animals also have abnormal bone structure, thinning in all three middle ear ossicles, and thinning of the incus body and the manubrium and processus brevis of the malleus (9).  The animals have abnormal osteoclast differentiation and decreased bone mineral density (8;9).  The animals also have increased osteoclast cell numbers in the metaphyseal region (10).

Tnfrsf11btm1Wss/tm1Wss; MGI:2183229

either: (involves: 129X1/SvJ * C57BL/6) or (involves: 129X1/SvJ * Black Swiss)

Approximately 15% of mice die prior to weaning likely from vertebral or endochondral bone fractures (11).  The parietal bones of the skull are thin and have increased porosity (11).  These mice exhibit decreased bone mineral density and osteoporotic by 1-2 months (11). The large arteries, including the aorta and in the kidney, exhibit some calcification as early as 2 weeks after birth and marked calcification by 2 months of age (11).
