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) <ref name="two"/> A Junius, F.K., Mackay, J.P., Bubb, W.A., Jensen, S.A., Weiss, A.S., King, G.F. 2006. Nuclear Magnetic Resonance Characterization of the Jun Leucine Zipper Domain: Unusual Properties of Coiled-Coil Interfacial Polar Residues?</ref>. The strand becomes an elongated coiled coil. This is formed by residues at the a and d positions in each of the two monomers, whereby they create hydrophobic centers which conform to the "knobs into holes" model by Crick. <ref name="two"/>. amino acids at these a and d positions are each surrounded by 4 additional residues from adjacent a-helix monomer <ref name="two"/>. | The structure of c-Jun is comprised of a leucine zipper as previously stated.
