WebApr 23, 2024 · Correlation between RA and CTCF-binding in the Hoxa cluster in F9 cells. Alongside RA, CTCF is known to regulate the progressive transcription of the Hoxa cluster genes by binding to one or more of the seven CBSs within the cluster. CBSs are found in various locations across the genome, one of them being at TAD boundaries. Web(also known as CBS or CTCF-binding sites) within the HoxA locus can organize HoxA chromatin structures and play sig-niﬁcant regulatory roles in ESC differentiation and leukemo-genesis (26, 35, 36).
