BZIP domain


 * This article is about the protein domain. For the compression algorithm, see Bzip2.

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 for the dimerization of two DNA binding regions. The DNA binding region comprises a number of basic aminoacids such as arginine and lysine.

bZIP domain containing proteins

 * AP-1 fos/jun heterodimer that forms a transcription factor
 * Jun-B transcription factor
 * CREB cAMP response element transcription factor
 * OPAQUE2 (O2) transcription factor of the 22-kD zein gene that encodes a class of storage proteins in the endosperm of maize (Zea Mays) kernels
