Introduction
The c-Jun protein is a member of transcription factors which consist of a basic region leucine zipper region [1]. All these leucine zipper factors bind to DNA in one of two states: homo or heterodimers [1].. In conjunction with the c-Fos protein these two proteins bind to specific regions of DNA strands. Together these two proteins form the c-fos/c-jun complex which help regulate cell growth and differentiation [1]. Regulation of the complex iteslf is done by interactions between the protein and DNA in addition to the protein-protein interactions between each of the leucine zipper domains [1].
Structure Overview
The structure of c-Jun is comprised of a leucine zipper as previously stated. This dimerization motif may be in one of two classes, both of which are required for DNA-binding transcription factors; the basic-domain leucine zipper proteins (bZIP) and the basic helix loop-helix-leucine zipper proteins(bHLH-ZIP)[3].
