CC -!- FUNCTION: Transcriptional regulator which is crucial for the
CC development and inhibitory function of regulatory T-cells (Treg). Plays
CC an essential role in maintaining homeostasis of the immune system by
CC allowing the acquisition of full suppressive function and stability of
CC the Treg lineage, and by directly modulating the expansion and function
CC of conventional T-cells. Can act either as a transcriptional repressor
CC or a transcriptional activator depending on its interactions with other
CC transcription factors, histone acetylases and deacetylases. The
CC suppressive activity of Treg involves the coordinate activation of many
CC genes, including CTLA4 and TNFRSF18 by FOXP3 along with repression of
CC genes encoding cytokines such as interleukin-2 (IL2) and interferon-
CC gamma (IFNG). Inhibits cytokine production and T-cell effector function
CC by repressing the activity of two key transcription factors, RELA and
CC NFATC2 (PubMed:15790681). Mediates transcriptional repression of IL2
CC via its association with histone acetylase KAT5 and histone deacetylase
CC HDAC7 (By similarity). Can activate the expression of TNFRSF18, IL2RA
CC and CTLA4 and repress the expression of IL2 and IFNG via its
CC association with transcription factor RUNX1 (PubMed:17377532). Inhibits
CC the differentiation of IL17 producing helper T-cells (Th17) by
CC antagonizing RORC function, leading to down-regulation of IL17
CC expression, favoring Treg development (PubMed:18368049). Inhibits the
CC transcriptional activator activity of RORA (By similarity). Can repress
CC the expression of IL2 and IFNG via its association with transcription
CC factor IKZF4 (PubMed:19696312). {ECO:0000250|UniProtKB:Q9BZS1,
CC ECO:0000269|PubMed:15790681, ECO:0000269|PubMed:17377532,
CC ECO:0000269|PubMed:18368049, ECO:0000269|PubMed:19696312}.
CC -!- SUBUNIT: Homodimer. Dimerization is essential for its transcriptional
CC regulator activity. Interacts with IKZF3 (By similarity). Interacts
CC (via LXXLL motif) with isoform 4 of RORA (via AF-2 motif) (By
CC similarity). Interacts with STUB1 and HSPA1A/B. Interacts with IKZF4,
CC HDAC7 and KAT5. Interacts with RUNX1, RUNX2, RUNX3 and NFATC2.
CC Interacts with RORC. Interacts with HDAC9 in the absence of T-cell
CC stimulation (By similarity). Interacts with RELA, PPP1CA, PPP1CB,
CC PPP1CG, HSPA8 and USP7 (By similarity). {ECO:0000250|UniProtKB:Q9BZS1,

CC Q99JB6; Q8C2S0: Usp44; NbExp=3; IntAct=EBI-10956246, EBI-26303241;
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00089,
CC ECO:0000269|PubMed:17377532, ECO:0000269|PubMed:18368049}. Cytoplasm
CC {ECO:0000250|UniProtKB:Q9BZS1}. Note=Predominantly expressed in the
CC cytoplasm in activated conventional T-cells whereas predominantly
CC expressed in the nucleus in regulatory T-cells (Treg) (By similarity).
CC The 41 kDa form derived by proteolytic processing is found exclusively
CC in the chromatin fraction of activated Treg cells.
CC {ECO:0000250|UniProtKB:Q9BZS1, ECO:0000269|PubMed:19117830}.
CC -!- TISSUE SPECIFICITY: High level of expression in thymus and spleen.
CC -!- INDUCTION: By TGFB1 in T-cells. Down-regulated in regulatory T-cells
CC (Treg) during inflammation. {ECO:0000269|PubMed:18368049,
CC ECO:0000269|PubMed:23973223}.
CC -!- DOMAIN: The fork-head DNA-binding domain is essential for its
CC dimerization and interaction with NFATC2.
CC {ECO:0000250|UniProtKB:Q9BZS1}.
CC -!- PTM: Acetylation on lysine residues stabilizes FOXP3 and promotes
CC differentiation of T-cells into induced regulatory T-cells (iTregs)
CC associated with suppressive functions (PubMed:22312127). Acetylation is
CC mediated by a coordinated action of KAT5 and EP300/p300
CC acetyltransferases: EP300/p300 is required to enhance KAT5
CC autoacetylation, promoting acetylation of FOXP3 by KAT5 (By
CC similarity). Deacetylated by SIRT1 (PubMed:22312127).
CC {ECO:0000250|UniProtKB:Q9BZS1, ECO:0000269|PubMed:22312127}.
CC -!- PTM: Polyubiquitinated, leading to its proteasomal degradation in
CC regulatory T-cells (Treg) which is mediated by STUB1 in a HSPA1A/B-
CC dependent manner. Deubiquitinated by USP7 leading to increase in
CC protein stability. {ECO:0000269|PubMed:23973222,
CC ECO:0000269|PubMed:23973223}.
CC -!- PTM: Phosphorylation at Ser-418 regulates its transcriptional repressor
CC activity and consequently, regulatory T-cells (Treg) suppressive
CC function (By similarity). Phosphorylation by CDK2 negatively regulates
CC its transcriptional activity and protein stability.
CC {ECO:0000250|UniProtKB:Q9BZS1, ECO:0000269|PubMed:23853094}.
CC -!- PTM: Undergoes proteolytic cleavage in activated regulatory T-cells
CC (Treg), and can be cleaved at either the N- or C-terminal site, or at
CC both sites. Treg expressing the form cleaved at C-terminal site or both
CC N- and C-terminal sites exhibit an increased induction of IL10 and an
CC increased capacity to suppress proliferation of conventional T-cells in
CC vitro. Treg expressing the form cleaved at only the C-terminal site are
CC highly effective at preventing experimental colitis in an in vivo model
CC of inflammatory bowel disease. {ECO:0000269|PubMed:19117830}.
CC -!- DISEASE: Note=Defects in Foxp3 are the cause of the scurfy phenotype
CC (sf). It results in a lethal disorder of immunoregulation,
CC characterized by infections, diarrhea, anemia, thrombocytopenia,
CC hypogonadism, gastrointestinal bleeding, lymphadenopathy and
CC leukocytosis.
