Intasome interaction with the N-terminal histone H2A tail. a Histone H2A residues Lys-9 and Arg-11 play a role in the intasome-NCP interaction. b, c Pull-down with immobilised intasome binding to NCP bearing deletions b or amino acid substitutions c in the H2A N-terminal tail. NΔ4, NΔ8, NΔ12, NCP variants lacking the first 4, 8 or 12 residues fo histone H2A
