The Basic Leucine Zipper Domain (bZIP domain) is found in many DNA binding eukaryotic proteins. One part of the domain contains a region that mediates sequence specific DNA binding properties and the leucine zipper that is required for the dimerization of two DNA binding regions. The DNA binding region comprises a number of basic aminoacids such as arginine and lysine.
