  • FUNCTION Transcription factor that recognizes and binds to the AP-1 consensus motif 5'-TGA[GC]TCA-3' (PubMed:10995748, PubMed:22083952). Heterodimerizes with proteins of the FOS family to form an AP-1 transcription complex, thereby enhancing its DNA binding activity to the AP-1 consensus sequence 5'-TGA[GC]TCA-3' and enhancing its transcriptional activity (By similarity). Together with FOSB, plays a role in activation-induced cell death of T cells by binding to the AP-1 promoter site of FASLG/CD95L, and inducing its transcription in response to activation of the TCR/CD3 signaling pathway (PubMed:12618758). Promotes activity of NR5A1 when phosphorylated by HIPK3 leading to increased steroidogenic gene expression upon cAMP signaling pathway stimulation (PubMed:17210646). Involved in activated KRAS-mediated transcriptional activation of USP28 in colorectal cancer (CRC) cells (PubMed:24623306). Binds to the USP28 promoter in colorectal cancer (CRC) cells (PubMed:24623306).FUNCTION (Microbial infection) Upon Epstein-Barr virus (EBV) infection, binds to viral BZLF1 Z promoter and activates viral BZLF1 expression.SUBUNIT Heterodimer with either BATF3 or ATF7 (PubMed:10376527, PubMed:12087103, PubMed:15467742). Heterodimer with FOS (By similarity). Heterodimer with FOSB isoform 1 and 2 (By similarity). Component of an AP-1 transcription factor complex composed of JUN-FOS heterodimers (By similarity). As part of the AP-1 transcription factor complex, forms heterodimers with FOSB, thereby binding to the AP-1 consensus sequence and stimulating transcription (By similarity). Interacts with FOS and FOSB isoform 1 and 2 (By similarity). The ATF7/JUN heterodimer is essential for ATF7 transactivation activity (PubMed:10376527). Interacts with TSC22D3 (via N-terminus); the interaction inhibits the binding of active AP1 to its target DNA (By similarity). Interacts with HIVEP3 and MYBBP1A (By similarity). Interacts with SP1, SPIB and TCF20 (PubMed:10196196, PubMed:16478997, PubMed:8663478). Interacts with COPS5; the interaction leads indirectly to its phosphorylation (PubMed:8837781). Component of the SMAD3/SMAD4/JUN/FOS/complex which forms at the AP1 promoter site (PubMed:10995748). The SMAD3/SMAD4 heterodimer acts synergistically with the JUN/FOS heterodimer to activate transcription in response to TGF-beta (PubMed:9732876). 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 (PubMed:10995748). Interacts with methylated RNF187 (PubMed:20852630, PubMed:23624934). Binds to HIPK3. Interacts (when phosphorylated) with FBXW7 (PubMed:14739463). Found in a complex with PRR7 and FBXW7 (PubMed:27458189). Interacts with PRR7 and FBXW7; the interaction inhibits ubiquitination-mediated JUN degradation promoting its phosphorylation and transcriptional activity (PubMed:27458189). Interacts with RBM39 (By similarity). Interacts with PAGE4 (PubMed:24263171, PubMed:24559171, PubMed:26242913). Interacts with ARK2N and CSNK2B; the interaction with ARK2N is mediated by CSNK2B (PubMed:31341047).INTERACTION Expressed in the developing and adult prostate and prostate cancer cells.PTM Ubiquitinated by the SCF(FBXW7), leading to its degradation (PubMed:14739463, PubMed:27458189). Ubiquitination takes place following phosphorylation, that promotes interaction with FBXW7 (PubMed:14739463).PTM Phosphorylated by CaMK4 and PRKDC; phosphorylation enhances the transcriptional activity. Phosphorylated by HIPK3. Phosphorylated by DYRK2 at Ser-243; this primes the protein for subsequent phosphorylation by GSK3B at Thr-239. Phosphorylated at Thr-239, Ser-243 and Ser-249 by GSK3B; phosphorylation reduces its ability to bind DNA. Phosphorylated by PAK2 at Thr-2, Thr-8, Thr-89, Thr-93 and Thr-286 thereby promoting JUN-mediated cell proliferation and transformation. Phosphorylated by PLK3 following hypoxia or UV irradiation, leading to increase DNA-binding activity.PTM Acetylated at Lys-271 by EP300.SIMILARITY Belongs to the bZIP family. Jun subfamily.
