Transcriptional repressor CTCF also known as 11-zinc finger protein or CCCTC-binding factor is a transcription factor that in humans is encoded by the CTCF gene. CTCF is involved in many cellular processes, including transcriptional regulation, insulator activity, V(D)J recombination and regulation of chromatin architecture. WebWe found only 41 differentially called CTCF-binding peaks out of a total of 31,840 called peaks (Figures 2 A and S2; Table S3). Interestingly, 5 out of these 41 binding peaks that were conserved in CTCF-deleted patients correspond to the TCRAD locus and were lost in CTCF wild-type patients with T-ALL due to TCRD recombination (Figure 2 B).
