Similarity between PAN and other plant bZIP proteins. (Top) Comparison of the PAN bZIP regions to other plant bZIP proteins: the Arabidopsis protein TGA1 (Schindler et al. 1992a), the wheat protein HBP-1b (Tabata et al. 1991), the maize protein OBF 3.1 and OBF 3.2 (Foley et al. 1993), the tobacco protein TGA1a (Katagiri et al. 1989), and the Arabidopsis proteins GBF1, GBF2, and GBF3 (Schindler et al. 1992b). Asterisks (*) indicate leucine residues within the leucine zipper domain. (Middle) Schematic presentation of PAN, indicating the positions of the basic region (BR), the leucine zipper domain (LZ), and the two glutamine-rich regions (QI and QII). (Bottom) Sequence alignments within the carboxy-terminal glutamine-rich domains of PAN and the TGACGT/C-binding proteins shown in the top. Glutamine residues within the glutamine-rich regions of PAN are indicated by dots. Identical amino acids are shown as shaded boxes. Numbers to the left refer to the amino acid positions within individual proteins.
