Plays an essential role in maintaining homeostasis of the immune system by allowing the acquisition of full suppressive function and stability of the Treg lineage, and by ly modulating the expansion and function of conventional T-cells. Can act either as a transcriptional repressor or a transcriptional activator depending on its interactions with other transcription factors, histone acetylases and deacetylases. The suppressive activity of Treg involves the coordinate activation of many genes, including CTLA4 and TNFRSF18 by FOXP3 along with repression of genes encoding cytokines such as interleukin-2 (IL2) and interferon- gamma (IFNG). Inhibits cytokine production and T-cell effector function by repressing the activity of two key transcription factors, RELA and NFATC2 (PubMed:15790681). Mediates transcriptional repression of IL2 via its association with histone acetylase KAT5 and histone deacetylase HDAC7 (PubMed:17360565). Can activate the expression of TNFRSF18, IL2RA and CTLA4 and repress the expression of IL2 and IFNG via its association with transcription factor RUNX1 (PubMed:17377532). Inhibits the differentiation of IL17 producing helper T-cells (Th17) by antagonizing RORC function, leading to down-regulation of IL17 expression, favoring Treg development (PubMed:18368049). Inhibits the transcriptional activator activity of RORA (PubMed:18354202). Can repress the expression of IL2 and IFNG via its association with transcription factor IKZF4 (By similarity). .\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eScientific background (datasheet):\u003c\/strong\u003e FOXP3 (forkhead box P3) is a protein involved in immune system responses. The human FOXP3 genes contain 11 coding exons. Exon-intron boundaries are identical across the coding regions of the mouse and human genes. By genomic sequence analysis, the FOXP3 gene maps to the p arm of the X chromosome (specifically, Xp11.23). A member of the FOX protein family, FOXP3 appears to function as a master regulator in the development and function of regulatory T cells. While the precise control mechanism has not yet been established, FOX proteins belong to the forkhead\/winged-helix family of transcriptional regulators and are presumed to exert control via similar DNA binding interactions during transcription.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCellular localization (datasheet):\u003c\/strong\u003e Nucleus . Cytoplasm . Predominantly expressed in the cytoplasm in activated conventional T-cells whereas predominantly expressed in the nucleus in regulatory T-cells (Treg). The 41 kDa form derived by proteolytic processing is found exclusively in the chromatin fraction of activated Treg cells (By similarity). .\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSequence similarities (datasheet):\u003c\/strong\u003e Contains 1 C2H2-type zinc finger.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCommonly studied in contexts related to Adaptive Immunity,Cell Biology,Cell Cycle,Cell Division,Domain Families,Epigenetics and Nuclear Signaling,Forkhead Box,Immunology,Transcription.\u003c\/li\u003e\n\u003cli\u003eSupports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.\u003c\/li\u003e\n\u003cli\u003eUseful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blot (WB):\u003c\/strong\u003e Compare relative target abundance and apparent size\/isoforms across samples; interpret bands in light of expected MW and potential PTMs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e Measure target abundance in compatible matrices using a standard-curve readout; ensure dilution linearity and appropriate controls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e Assess tissue distribution and cell-type patterns; interpret staining with appropriate negative controls and antigen context.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e Quantify target-positive populations in single-cell suspensions; pair with viability and isotype\/FMO controls conceptually.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConsider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross-reactivity (datasheet):\u003c\/strong\u003e No cross-reactivity with other proteins\u003c\/li\u003e\n\u003cli\u003eUse appropriate positive and negative controls (e.g., KO\/KD, blocking peptide, or isotype controls) to support specificity interpretation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAs a polyclonal antibody, this reagent may recognize multiple epitopes on the target, which can improve detection robustness but may require careful specificity controls.\u003c\/p\u003e\u003c!-- Sources (internal):\u003cbr\u003e- Product datasheet fields provided in this catalog row (vendor-supplied).\u003cbr\u003e- UniProt Knowledgebase (general protein annotations): https:\/\/www.uniprot.org\/\u003cbr\u003e- NCBI Gene (general gene-level references): https:\/\/www.ncbi.nlm.nih.gov\/gene\/\u003cbr\u003e--\u003e","brand":"Boster Bio","offers":[{"title":"100 ug\/vial \/ Unconjugated","offer_id":53069812990317,"sku":"RP1032","price":370.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Biotin","offer_id":53070392721773,"sku":"RP1032-Biotin","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Cy3","offer_id":53070392754541,"sku":"RP1032-Cy3","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro488","offer_id":53070392787309,"sku":"RP1032-Fluoro488","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro550","offer_id":53070392820077,"sku":"RP1032-Fluoro550","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro594","offer_id":53070392852845,"sku":"RP1032-Fluoro594","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ FITC","offer_id":53070392885613,"sku":"RP1032-FITC","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ HRP","offer_id":53070392918381,"sku":"RP1032-HRP","price":570.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ APC","offer_id":53070392951149,"sku":"RP1032-APC","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ PE","offer_id":53070392983917,"sku":"RP1032-PE","price":820.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Fluoro647","offer_id":53070393016685,"sku":"RP1032-Fluoro647","price":670.0,"currency_code":"USD","in_stock":true},{"title":"100 ug\/vial \/ Carrier Free","offer_id":53070393049453,"sku":"RP1032-carrier-free","price":370.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/rp1032-fimmu-14-1238694-g001.jpg?v=1772612650","url":"https:\/\/www.ebiohippo.com\/products\/anti-forkhead-box-protein-p3-foxp3-antibody-bha21007533","provider":"BioHippo","version":"1.0","type":"link"}
