Function
The protein expressed by the FOXP3 gene is a transcriptional regulator critical for the development and inhibitory function of regulatory T-cells (Treg). It plays an essential role in immune system homeostasis by ensuring the suppressive function and stability of Treg cells and directly influencing conventional T-cells' expansion and function. FOXP3 can function as either a transcriptional repressor or activator, depending on its interactions with other factors, such as transcription factors, histone acetylases, and deacetylases. It co-activates genes like CTLA4 and TNFRSF18 and represses cytokine genes, including interleukin-2 (IL2) and interferon-gamma (IFNG), and inhibits cytokine production by repressing the activity of transcription factors RELA and NFATC2. FOXP3's association with histone acetylase KAT5 and deacetylase HDAC7 mediates IL2 repression, while its interaction with transcription factor RUNX1 modulates the expression of TNFRSF18, IL2RA, CTLA4, IL2, and IFNG. It also antagonizes RORC to inhibit the differentiation of IL17 producing helper T-cells (Th17), leading to reduced IL17 expression and promoting Treg development, while inhibiting the transcriptional activator activity of RORA.

- 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.
