Fos and Jun dimerize to form Activator Protein-1 (AP-1), a transcriptional factor that binds to the 12-O-tetradecanoylphorbol 13-acetate (TPA) response element (TRE) of several cellular and viral genes including human collagenase, metallothionein IIa, stromelysin, interleukin 2, SV40 and polyoma.
Fos and Jun contain the ‘leucine-zipper’ motif that allows for dimerization and an adjacent basic domain required for biological activity.
The functionally active form of Fos is in a heterodimer with a member of the Jun family.
While Jun family members can form functional homodimers, studies indicate that Fos family members do not self-associate and therefore do not bind DNA on their own.
The various dimers differ in their ability to transactivate AP-1 dependent genes.
