WebNMR investigations indicate that racemic [Co(phen)2(HPIP)]Cl3 [HPIP = 2-(2-hydroxyphenyl) imidazo [4,5-f][1,10] phenanthroline] binds the decanucleotide by intercalation: the HPIP ligand selectively inserts between the stacked bases from the minor groove at the terminal regions and from the major groove at the sheared region. WebThe protein's versatility in binding to different DNA sequences arises from the nature of its DNA-binding domain and epigenetic modifications. The DNA-binding domain of CTCF is evolutionarily conserved and contains 11 zinc-finger motifs, which sequentially interact with the DNA major groove containing specific nucleotide bases.
