Post-translational modificationi

Phosphorylated by CaMK4 and PRKDC; phosphorylation enhances the transcriptional activity. Phosphorylated by HIPK3. Phosphorylated by DYRK2 at Ser-246; this primes the protein for subsequent phosphorylation by GSK3B at Thr-242. Phosphorylated at Thr-242, Ser-246 and Ser-252 by GSK3B; phosphorylation reduces its ability to bind DNA. Phosphorylated by PLK3 following hypoxia or UV irradiation, leading to increase DNA-binding activity (By similarity).By similarity
Ubiquitinated by the SCF(FBXW7), leading to its degradation. Ubiquitination takes place following phosphorylation, that promotes interaction with FBXW7.By similarity

Interactioni

Subunit structurei

Heterodimer with either FOS or BATF3 or ATF7 (PubMed:9154808). The ATF7/JUN heterodimer is essential for ATF7 transactivation activity. Interacts with MYBBP1A, SP1, SPIB and TCF20. Interacts with COPS5; indirectly leading to its phosphorylation. Interacts with DSIPI; this interaction inhibits the binding of active AP1 to its target DNA. Interacts with HIVEP3. Component of the SMAD3/SMAD4/JUN/FOS/complex which forms at the AP1 promoter site. The SMAD3/SMAD4 heterodimer acts synergistically with the JUN/FOS heterodimer to activate transcription in response to TGF-beta. Interacts (via its basic DNA binding and leucine zipper domains) with SMAD3 (via an N-terminal domain); the interaction is required for TGF-beta-mediated transactivation of the SMAD3/SMAD4/JUN/FOS/complex (By similarity). Binds to HIPK3 (By similarity). Interacts with methylated RNF187 (PubMed:20852630). Interacts (when phosphorylated) with FBXW7 (By similarity).By similarity2 Publications
