Figure 1.4. Sequence alignments of the bZIP domains of GCN4 and the Jun and Fos familes.

The boxed residues delineate the basic domain consensus sequence N--AA--(C/S)R and the heptad repeat of leucine residues.

marks the position of conserved C-terminal histidines within the Jun and Fos familes. Highly conserved a-position polar residues are marked with arrows.
