Structural highlights
DiseaseTNF11_MOUSE Note=Deficiency in Tnfsf11 results in failure to form lobulo-alveolar mammary structures during pregnancy, resulting in death of newborns. Trance-deficient mice show severe osteopetrosis, with no osteoclasts, marrow spaces, or tooth eruption, and exhibit profound growth retardation at several skeletal sites, including the limbs, skull, and vertebrae and have marked chondrodysplasia, with thick, irregular growth plates and a relative increase in hypertrophic chondrocytes. FunctionTNF11_MOUSE Cytokine that binds to TNFRSF11B/OPG and to TNFRSF11A/RANK. Osteoclast differentiation and activation factor. Augments the ability of dendritic cells to stimulate naive T-cell proliferation. May be an important regulator of interactions between T-cells and dendritic cells and may play a role in the regulation of the T-cell-dependent immune response. May also play an important role in enhanced bone-resorption in humoral hypercalcemia of malignancy. Evolutionary Conservation![]() Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedBone remodeling involves the resorption of bone by osteoclasts and the synthesis of bone matrix by osteoblasts. Receptor activator of NF-kappa B ligand (RANKL, also known as ODF and OPGL), a member of the tumor necrosis factor (TNF) family, triggers osteoclastogenesis by forming a complex with its receptor, RANK. We have determined the crystal structure of the extracellular domain of mouse RANKL at 2.2-A resolution. The structure reveals that the RANKL extracellular domain is trimeric, which was also shown by analytical ultracentrifugation, and each subunit has a beta-strand jellyroll topology like the other members of the TNF family. A comparison of RANKL with TNF beta and TNF-related apoptosis-inducing ligand (TRAIL), whose structures were determined to be in the complex form with their respective receptor, reveals conserved and specific features of RANKL in the TNF superfamily and suggests the presence of key residues of RANKL for receptor binding.
