Verification Images
-
Western blot analysis was performed on extracts from CHO-K1(Flag-FOXP3) (lane 1, 15 μg) using FOXP3 Mouse (7H9) mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non - fat milk in TBST at 4°C overnight. The primary antibody (1:1000 dilution) and the loading control antibody (beta-Actin(HRP), HY-P80993, 1:5000 dilution) was incubated in 5% non-fat milk in TBST for 1 hour at 37°C. Goat Anti - Mouse IgG - HRP Secondary Antibody (1:20000 dilution) was then applied for 40 minutes at 37°C. -
Immunohistochemical analysis of paraffin-embedded human Esophageal Carcinoma tissue using FOXP3 antibody was performed. The section was pretreated using high-temperature and high-pressure mediated EDTA antigen retrieval buffer (pH 9.0), for 5 minutes. The tissues were incubated with primary antibody (HY-P80678, 1:1000 dilution) at room temperature for 60 minutes. Detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. The tissues were counterstained with hematoxylin and mounted with neutral balsam mounting medium. -

Tyramide signaling amplification based immunofluorescence was performed on paraffin-embedded human Liver Cancer tissue using FOXP3 antibody. Antigen retrieval was performed in EDTA buffer pH 9.0 (95 °C, 20 min) followed by cooling to RT. Then incubated with primary antibody (HY-P80678, 1:1000 dilution) at room temperature for 60 minutes and HRP conjugated secondary antibody for 10 minutes. Fluorescence was then developed with TSA520. The tissues were counterstained with DAPI and mounted with Anti-fade mounting medium. -

Background
-
Function
FOXP3, so called scurfin, belongs to the forkhead box protein P (FOXP) family. FOXP3 is critically involved in differentiation and function of regulatory T cells or CD4+/CD25+ regulatory T (Treg) cells for cancer immunotherapy. FOXP3 modulates Treg development and functions by immune evasion of tumor cells through imbalance of immunoediting and immunosurveillance in some cancers. FOXP3 is associated with IL-17, RUNX1, STAT3, NF-κB, FOXO3 and other cofactors such as EOS (Ikzf4), interferon regulatory factor 4 (IRF4), special AT-rich sequence-binding protein-1 (SATB1) and GATA1.

Expression
Induction: Down-regulated in regulatory T-cells (Treg) during inflammation. Up-regulated by FOXO3
-
Isoforms & Post-Translational Modification
FOXP3 has four isomers: Q9BZS1-1: 47244 Da (predicted); Q9BZS1-2: 43410 Da (predicted); Q9BZS1-3: 49843 Da (predicted); Q9BZS1-4: 44407 Da (predicted).
Polyubiquitinated, leading to its proteasomal degradation in regulatory T-cells (Treg) which is mediated by STUB1 in a HSPA1A/B-dependent manner. -
