Schematic diagram of human CTCF. (A) Zinc finger domains. Amino acid sequences of each linker domain are indicated, and candidate amino acid residues for phosphorylation are underlined. (B) The amino acid sequence of human CTCF. Zinc finger motifs are highlighted in gray. All known phosphorylation amino acid positions are marked. Red characters indicate phosphorylation sites identified by proteomics analyses in 9 and 10. Blue and green characters indicate phosphorylation sites analyzed in 11 and 17, respectively.
