Leucine Zipper
The leucine zipper is the dimerization domain of the B-ZIP (basic-region leucine zipper) class of eukaryotic transcription factors (Vinson et al., 1989). The name arose because leucines occur every seven amino acids in this dimerization domain.These leucines are critical for the dimerization and DNA binding of B-ZIP proteins. The leucine zipper is a left-handed parallel dimeric coiled-coil, a s...
متن کاملA Petunia Homeodomain-Leucine Zipper Protein, PhHD-Zip, Plays an Important Role in Flower Senescence
Flower senescence is initiated by developmental and environmental signals, and regulated by gene transcription. A homeodomain-leucine zipper transcription factor, PhHD-Zip, is up-regulated during petunia flower senescence. Virus-induced gene silencing of PhHD-Zip extended flower life by 20% both in unpollinated and pollinated flowers. Silencing PhHD-Zip also dramatically reduced ethylene produc...
متن کاملGenome-wide analysis of the homeodomain-leucine zipper (HD-ZIP) gene family in peach (Prunus persica).
In this study, 33 homeodomain-leucine zipper (HD-ZIP) genes were identified in peach using the HD-ZIP amino acid sequences of Arabidopsis thaliana as a probe. Based on the phylogenetic analysis and the individual gene or protein characteristics, the HD-ZIP gene family in peach can be classified into 4 subfamilies, HD-ZIP I, II, III, and IV, containing 14, 7, 4, and 8 members, respectively. The ...
متن کاملLeucine Zipper Mutants
Coiled-coil sequences in proteins consist of heptad repeats containing two characteristic hydrophobic positions. The role of these buried hydrophobic residues in determining the structures of coiled coils was investigated by studying mutants of the GCN4 leucine zipper. When sets of buried residues were altered, two-, three-, and four-helix structures were formed. The x-ray crystal structure of ...
متن کاملMaternal embryonic leucine zipper kinase is a novel target for proliferation-associated high-risk myeloma
Treatment of high-risk patients is a major challenge in multiple myeloma. This is especially true for patients assigned to the gene expression profiling-defined proliferation subgroup. Although recent efforts have identified some key players of proliferative myeloma, genetic interactions and players that can be targeted with clinically effective drugs have to be identified in order to overcome ...
