MeSH definition : A homodimerization protein interaction domain occurring at the N terminus of proteins
that contain multiple copies of either CYS2-HIS2 ZINC FINGERS or KELCH REPEATS. It
is characterized by a tightly intertwined dimer with an extensive hydrophobic interface.
A surface-exposed groove lined with conserved amino acids is formed at the dimer interface,
suggesting a peptide-binding site. Many BTB proteins are transcriptional regulators
that are thought to regulate CHROMATIN structure.;
