Basic leucine zipper (bZIP) domain of Cyclic AMP-responsive element-binding protein-like 2 (CREBL2): a DNA-binding and dimerization domain; CREBL2 is a bZIP transcription factor that interacts with CREB and plays a critical role in adipogenesis and lipogenesis. Its overexpression upregulates the expression of PPARgamma and CEBPalpha to promote adipogenesis as well as accelerate lipogenesis by increasing GLUT1 and GLUT4. bZIP factors act in networks of homo and heterodimers in the regulation of a diverse set of cellular processes. The bZIP structural motif contains a basic region and a leucine zipper, composed of alpha helices with leucine residues 7 amino acids apart, which stabilize dimerization with a parallel leucine zipper domain. Dimerization of leucine zippers creates a pair of the adjacent basic regions that bind DNA and undergo conformational change. Dimerization occurs in a specific and predictable manner resulting in hundreds of dimers having unique effects on transcription.
