|bZIP transcription factor|
CREB (top) is a transcription factor capable of binding DNA via the bZIP domain (bottom) and regulating gene expression.

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.
