| Source name |
Bcl11b sufficient Tn cells
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57BL/6
cell type: Sorted CD4+YFP+ cells
genotype: Foxp3-IRES-YFP-Cre
antibody: Input DNA
|
| Growth protocol |
Single cell supensions were prepared from drainig lymphnodes and spleen. Respective cell population were sorted using BD Moflo-XDP cell sorter and fixed.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Sheared Chromatin were cleared and protein-DNA complexes were isolated with antibody-magnetic bead complex.
ChIP-seq library for each sample were prepared according to manufacturer (NEXTFLEX® ChIP-Seq Kit 5143-01) protocols. Briefly,purified immunoprecipitated DNA were end-repaired and size selected for 200–400-bp fragments with Agencourt AMPure XP beads (A63880) followed by Adenylation, barcoded adaptor-ligation and PCR amplification (15 cycles). Size distribution and concentration of each library was checked using Agilent Bioanalyzer. Equivalent amounts of barcoded libraries were pooled and sequenced using HiSeq 2500 (Illumina) instruments.

| Data processing |
The quality of sequenced reads (50 bp; paired-end) was measured using FastQC , and low quality portions of the sequenced reads were trimmed using Trim Galore (version 0.4.2; with Cutadapt (version 1.12).
The trimmed reads were mapped to the mouse genome (reference assembly mm10) using HISAT2 (version 2.1.0).
The mapped reads were sorted by genomic positions using Samtools (version 1.3) , and duplicated mapped reads were removed using Sambamba (version 0.6.5).
Biological replicates for each conditions were merged and the genomic binding sites (peaks) of a given protein were identified using HOMER (version 4.10.1) with a FDR-adjusted p-value cutoff of 0.001
The peaks overlapped with the blacklisted regions that show anomalous, unstructured, and high signal/read counts were discarded.
To identify reliable target genes of a given protein, peaks located 20 kb outside of the gene’s transcription start sites were removed.
To identify common (or specific) peaks between given conditions, the identified peaks in each condition were merged.
Merged peaks were used to define common or specific peaks using HOMER (getDifferentialPeaks) with default parameters.
Deeptools (version 2.5.3-2-503c71b) was used to draw heatmaps
