NCIt definition : The BTB/POZ domain is an approximately 120 amino acid long, hydrophobic region found
in two distinct classes of transcriptional regulators that contain either a C-terminal
basic leucine zipper motif (POK proteins) or a Zn-finger region (Bach proteins). This
domain has been shown to form homo-dimers in a number of BTB/POZ domain containing
proteins. (NCI);
