FRZB is also known as FRE or OS1. The protein encoded by this gene is a secreted protein that is involved in the regulation of bone development. Defects in this gene are a cause of female-specific osteoarthritis (OA) susceptibility. FRZB is a Wnt-binding protein especially important in embryonic development. It is a competitor for the cell-surface G-protein receptor Frizzled. FRZB is localized in the extracellular plasma membrane. Unlike frizzled, frzb lacks the 7 transmembrane domains normally found in G-protein-coupled receptors. It is still considered a homolog of frizzled because it contains a Cysteine Rich Domain (CRD), and because of its intracellular C-terminus which is crucial for signaling. Functional note: Soluble frizzled-related proteins (sFRPS) function as modulators of Wnt signaling through interaction with Wnts. They have a role in regulating cell growth and differentiation in specific cell types. SFRP3\/FRZB appears to be involved in limb skeletogenesis. Antagonist of Wnt8 signaling. Regulates chondrocyte maturation and long bone development. Reported localization: Secreted . Expression\/tissue context: Expressed primarily in the cartilaginous cores of the long bone during embryonic and fetal development and in the appendicular skeleton (6-13 weeks). At 13 weeks of gestation, transcripts were present in early chondroblasts of the tarsal bones of the foot, the carpal bones of the hands and the epiphysis of long bones. Highly expressed in placenta and heart, followed by brain, skeletal muscle, kidney and pancreas. Weakly expressed in lung and liver.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eCytoskeleton\/ECM: Researchers commonly examine how FRZB (Secreted frizzled-related protein 3) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e\n\u003cli\u003eExtracellular Matrix: Researchers commonly examine how FRZB (Secreted frizzled-related protein 3) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e\n\u003cli\u003eSecreted: Researchers commonly examine how FRZB (Secreted frizzled-related protein 3) relates to this theme using model systems and orthogonal readouts.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWestern blotting: compare relative FRZB (Secreted frizzled-related protein 3) levels across conditions; band patterns may reflect isoforms and processing.\u003c\/li\u003e\n\u003cli\u003eELISA-compatible use: when applicable, interpret signal as relative abundance across sample sets with consistent handling and dilution strategy.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eSpecificity notes:\u003c\/strong\u003e No cross reactivity with other proteins.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCross-reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFamily \/ similarity context:\u003c\/strong\u003e Belongs to the secreted frizzled-related protein (sFRP) family.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eIsoforms and PTMs:\u003c\/strong\u003e Apparent size and signal patterns can differ across splice isoforms, proteolytic processing, and post-translational modifications.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eControls:\u003c\/strong\u003e Include an isotype control (as relevant), no-primary control for imaging, and orthogonal validation such as KD\/KO samples when available.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProt entry for Q92765: https:\/\/www.uniprot.org\/uniprotkb\/Q92765\/entry - PubMed search (FRZB): https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=FRZB - NCBI Gene search (FRZB): https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=FRZB - Antibody validation concepts (NIH): https:\/\/www.nih.gov\/research-training\/rigor-reproducibility --\u003e","brand":"Boster Bio","offers":[{"title":"100 ug\/vial \/ Unconjugated","offer_id":53066820616557,"sku":"PB9372","price":370.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Biotin","offer_id":53066978460013,"sku":"PB9372-Biotin","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Cy3","offer_id":53066978492781,"sku":"PB9372-Cy3","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro488","offer_id":53066978525549,"sku":"PB9372-Fluoro488","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro550","offer_id":53066978558317,"sku":"PB9372-Fluoro550","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro594","offer_id":53066978591085,"sku":"PB9372-Fluoro594","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ FITC","offer_id":53066978623853,"sku":"PB9372-FITC","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ HRP","offer_id":53066978656621,"sku":"PB9372-HRP","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ APC","offer_id":53066978689389,"sku":"PB9372-APC","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ PE","offer_id":53066978722157,"sku":"PB9372-PE","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro647","offer_id":53066978754925,"sku":"PB9372-Fluoro647","price":670.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Carrier Free","offer_id":53066978787693,"sku":"PB9372-carrier-free","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/pb9372-1-WB-anti-frzb-sfrp-3-picoband-antibody.jpg?v=1772533268","url":"https:\/\/www.ebiohippo.com\/products\/anti-frzb-antibody-picoband-bha21000275","provider":"BioHippo","version":"1.0","type":"link"}
