From: Sequence and structural analysis of BTB domain proteins
Protein-protein interaction surfaces in BTB domains. Left column: the BTB monomer is shown in the same orientation for each of four structural families with the core fold in black, and the amino- and carboxy-terminal extensions in blue. Middle column: the monomers are shown with the protein-protein interaction surfaces shaded. Right column: the monomers are shown in their protein complexes.
