The relative arrangement of the two α-helices forming the leucine-zipper dimer in antiparallel mode is shown. Leu/Ile residues are found at the interface of the dimer characterized by a hydrophobic face and a hydrophilic one. A second hydrophobic platform and a hydrophilic one seem to be available for supplementary interactions. Hydrophobic residues are underlined.
