Function

Transcriptional regulator which is crucial for the development and inhibitory function of regulatory T-cells (Treg) (PubMed:17377532, PubMed:21458306, PubMed:23947341, PubMed:24354325, PubMed:24722479, PubMed:24835996, PubMed:30513302, PubMed:32644293). 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 directly modulating the expansion and function of conventional T-cells (PubMed:23169781). Can act either as a transcriptional repressor or a transcriptional activator depending on its interactions with other transcription factors, histone acetylases and deacetylases (PubMed:17377532, PubMed:21458306, PubMed:23947341, PubMed:24354325, PubMed:24722479). 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) (PubMed:17377532, PubMed:21458306, PubMed:23947341, PubMed:24354325, PubMed:24722479). 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).

Activity summary

FOXP3 also recognized as Forkhead box P3 is a transcription factor critical for immune system function. It weighs approximately 47 kDa. FOXP3 is mainly expressed in regulatory T cells (Tregs) which play a role in maintaining immune tolerance. Scientists primarily identify its presence in the nucleus where it facilitates transcriptional regulation. Methods like 'FOXP3 IHC' and 'FOXP3 IHC mouse' are useful for detecting this protein in tissue samples while 'FOXP3 antibodies' aid in research on this target. Techniques like 'FOXP3 staining' and 'FOXP3 flow cytometry' further allow for the analysis of its expression and function.

Biological function summary

This transcription factor operates by regulating the expression of a variety of genes involved in Treg cell development and function. FOXP3 can interact with other proteins to form complexes that modulate gene expression. Its role is essential in enabling Tregs to suppress immune responses a process necessary for preventing autoimmunity. The interaction extends to other key regulators within Tregs such as the protein complex 221D which may have overlapping functional responsibilities. 'FOXP3 236a/E7' reflects its genetic variants detectable in different studies providing insights into its biological functions.

Pathways

FOXP3 is a significant player within the immune regulation pathway. It integrates into the TGF-beta signaling pathway in which it controls the expression of genes important for Treg functions. The protein recruits other transcription factors like NF-kB coordinating intricate network regulations within immune cells. FOXP3's activity orchestrates the balance between immune activation and suppression ensuring a well-functioning immune response that prevents overreactions leading to autoimmune conditions.

Associated diseases and disorders

FOXP3 mutations or dysregulation can link to autoimmune diseases like immune dysregulation polyendocrinopathy enteropathy X-linked syndrome (IPEX). This transcription factor's malfunction implicates cancer where inadequate Treg function can either suppress antitumor immunity or result in tumor progression. Proteins such as CTLA-4 which is also involved in immune regulation connect to FOXP3 in these contexts emphasizing FOXP3’s significant role in maintaining immune homeostasis and its impact on disease development.

    IHC image of FOXP3 staining in a section of formalin-fixed paraffin-embedded normal human spleen* performed on a Leica BONDTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with Anti-FOXP3 antibody [EPR15038-69] ab191416, 5ug/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
