From: Loss of the insulator protein CTCF during nematode evolution
Conserved zinc finger region of tsCTCF. Multiple sequence alignment of the ZF domains of T. spiralis, human, and D. melanogaster CTCF. Similar and identical residues (grey), zinc coordinating residues (red, blue), and identical residues for DNA recognition (yellow) are indicated. ZF11 is missing in T. spiralis and is less conserved between D. melanogaster and man than ZF1 – 10.
