Acts as decoy receptor for TNFSF11\/RANKL and thereby neutralizes its function in osteoclastogenesis. Inhibits the activation of osteoclasts and promotes osteoclast apoptosis in vitro. Bone homeostasis seems to depend on the local ratio between TNFSF11 and TNFRSF11B. May also play a role in preventing arterial calcification. May act as decoy receptor for TNFSF10\/TRAIL and protect against apoptosis. TNFSF10\/TRAIL binding blocks the inhibition of osteoclastogenesis.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eQuantitative mapping of ligand\/receptor signaling to downstream phospho- and transcriptional programs.\u003c\/li\u003e\n\u003cli\u003eUse of recombinant standards to improve assay calibration and cross-study comparability.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eTNFRSF11B is a secreted protein, containing 2 death domains and 4 TNFR-Cys repeats. TNFRSF11B is a decoy receptor for the receptor activator of nuclear factor kappa B ligand (RANKL). By binding RANKL, TNFRSF11B inhibits nuclear kappa B (NF-κB) which is a central and rapid acting transcription factor for immune-related genes, and a key regulator of inflammation, innate immunity, and cell survival and differentiation. TNFRSF11B levels are influenced by voltage-dependent calcium channelsCav1.2. TNFRSF11B can reduce the production of osteoclasts by inhibiting the differentiation of osteoclast precursors (osteoclasts are related to monocytes\/macrophages and are derived from granulocyte\/macrophage-forming colony units (CFU-GM)) into osteoclasts and also regulates the resorption of osteoclasts in vitroand in vivo. TNFRSF11B binding to RANKL on osteoblast\/stromal cells, blocks the RANKL-RANK ligand interaction between osteoblast\/stromal cells and osteoclast precursors. This has the effect of inhibiting the differentiation of the osteoclast precursor into a mature osteoclast.\u003c\/p\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eStandard curve or spike-in reference for quantitative assays involving TNFRSF11B\u003c\/li\u003e\n\u003cli\u003eBinding interaction studies (e.g., SPR\/BLI or plate-based binding formats)\u003c\/li\u003e\n\u003cli\u003eCell-based stimulation studies with downstream marker readouts (conceptual)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRecombinant constructs may not capture all native isoforms or PTMs.\u003c\/li\u003e\n\u003cli\u003eConsider tag- or host-related effects when interpreting binding or activity.\u003c\/li\u003e\n\u003cli\u003eUse appropriate blanks and matrix\/control concepts to separate signal from background.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProtKB O00300 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/O00300 - NCBI Gene search: TNFRSF11B — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=TNFRSF11B - Ensembl search: TNFRSF11B — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=TNFRSF11B - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ - NCBI Bookshelf — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/books\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53053396582765,"sku":"CSB-AP004951HU-1MG","price":2126.0,"currency_code":"USD","in_stock":true},{"title":"500 ug","offer_id":53053514645869,"sku":"CSB-AP004951HU-500UG","price":1488.0,"currency_code":"USD","in_stock":true},{"title":"50 ug","offer_id":53053514678637,"sku":"CSB-AP004951HU-50UG","price":232.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-AP004951HU_290b7ccd-7bca-49c4-b61b-3601b47fc98b.jpg?v=1772177613","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-human-tumor-necrosis-factor-receptor-superfamily-member-11b-tnfrsf11b-active-bhp10506898","provider":"BioHippo","version":"1.0","type":"link"}
