Fig. S1. Treg-specific deletion of Bcl11b results in systemic autoimmunity comparable to that
observed in mouse lacking functional Foxp3 expression. (A) Intracellular staining to confirm Treg
cell specific deletion of Bcl11b in Bcl11bf/f

GFP cDNA followed by stop codons knocked into Foxp3 locus) euthanized at ~1 month of age. (C)
Appearance of representative lymph nodes and spleens harvested from ~1 month old WT, KO and
Foxp3GFPKO
mice. (D) Representative hematoxylin and eosin (H+E) stained histological sections of
indicated organs of WT, KO and Foxp3GFPKO
mice. Original magnification ×100. Data is representative
of at least 3 independent experiments. (Photo Credits: Parts B and C, Dipayan Rudra, Academy of
Immunology and Microbiology, Institute for Basic Science; Part D, Sinchita Roy-Chowdhuri,

Fig. S2. Marked immune activation in KO mice. (A) Quantification of expression of indicated
activation markers on CD4+Foxp3
- T-cells from lymph nodes and spleens of 3-5 weeks old WT (filled
red circles) and KO (filled black circles) mice. Each circle represents one animal. Data is from 2-3
independent experiments. (B) Representative FACS plots and quantification of CD44+CD62L
lo effector
Treg population in WT (red lines and filled circles) and KO (black lines and filled circles) mice. (C)
Quantification of expression of indicated activation markers on CD4+Foxp3
+ Treg cells from lymph
nodes and spleens of 3-5 weeks old WT and KO mice. Each circle represents one animal. Data is from
2-3 independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001, ***P < 0.0001 (Student’s t-test,
error bars, s.d.).
Fig. S3. Functional annotation and GSEA of Bcl11b-dependent up-regulated (Up) or down-
regulated (Down) genes. FACS plots demonstrating pre- and post-sort purity of Treg cells sorted from
WT and KO heterozygous female (het-KO and het-WT) mice, which were used to prepare libraries for
RNA-seq analysis. Data is representative of at least four identical experiments, for which 4-5 mice
were used per group in each sorting sessions. (B) Gene ontology (GO) term enrichment in the
“biological process” category of Bcl11b-dependent Up (right) or Down (left) genes. Top 12 GO terms
ranked according to the number of counts are plotted. Genes representing each category are listed in
Supplementary Table 1. (C, D) GSEA plots demonstrating negative correlation of Treg signature genes
with Bcl11b-dependent gene expression (genes activated in Treg cells compared to conventional T-
cells are Down (C), and genes repressed in Treg cells compared to conventional T-cells are Up (D) in
Bcl11b-deficient Treg cells compared to WT). Two independent GSEA data sets (left and right panels
that show similar results are shown. (E) GSEA analysis demonstrating “Foxp3-enriched” gene
expression clusters GAVIN_FOXP3_TARGET_CLUSTER_T4 and
GAVIN_FOXP3_TARGET_CLUSTER_P4 to be over-represented in Bcl11b-dependent Down genes.
Net enrichment scores (NES) and false discovery rate (FDR) q-values are shown for each plot.
Fig. S4. Motif analysis to identify potential transcription factor binding sites. Transcription factor
binding motif enrichment within 100 bp upstream or downstream of Bcl11b peaks corresponding to
genes exclusively harbouring Tn/Tr-common sites (A) or Tr-specific sites (B). P-values are indicated in
red. Sites with P value less than 1e-4 are not included.
Fig. S5. Characterization of genes harboring Lost or Gained Foxp3 peaks in Bcl11b-deficient Treg
cells. Additional examples of IGV tracks of Foxp3 ChIP-seq (blue) and corresponding ATAC-seq (red
and black) peaks of the indicated categories in WT and KO Treg cells. Grey arrows indicate ATAC-seq
peaks altered in KO Treg cells compared to WT. (B) Gene ontology analyses of “biological process”
category for genes which gained Foxp3 peaks, as well were 1.5 folds upregulated in Bcl11b-deficient
Treg cells. (C) Representative Foxp3 bound peaks and corresponding ATAC-seq peaks (grey arrows)
‘Gained’ in Bcl11b-deficient Treg cells, the corresponding genes for which are downregulated
compared to WT.
