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 to hold together (dimerize) two DNA binding regions. The DNA binding region comprises a number of basic amino acids such as arginine and lysine. Proteins containing this domain are transcription factors.[1][2]

bZIP transcription factors[edit]

bZIP transcription factors are found in all eukaryotes and form one of the largest families of dimerizing TFs.[3][4] An evolutionary study from 2008 revealed that 4 bZIP genes were encoded by the genome of the most recent common ancestor of all plants.[5] Interactions between bZIP transcription factors are numerous and complex [6][7][3] and play important roles in cancer development[8] in epithelial tissues, steroid hormone synthesis by cells of endocrine tissues,[9] factors affecting reproductive functions,[10] and several other phenomena that affect human health.
