ATACseq in BMEL cells invalidated or not for the expression of the three HP1 isoforms (CBX1, CBX3, CBX5)
Chromatin accessibility assay by ATACseq in BMEL cells. Three clones (TKO1, TKO2, TKO3) of BMEL TKO cells invalidated for the expression of the three HP1 isoforms (Cbx1-/-; Cbx3-/-; Cbx5-/-) were compared to three clones (Het1, Het32, Het35) of BMEL Het cells (Cbx1+/+; Cbx3+/+; Cbx5+/-) as controls.
