Background

Function

c-Jun, a basic leucine zipper transcription factor, regulates gene expression in response to multiple extracellular signals^[1]. It is a central component of the activator protein-1 (AP-1) complex, mediating cellular proliferation, differentiation, and stress responses^[2]^[3]. Mechanistically, c-Jun is primarily activated by phosphorylation through the c-Jun N-terminal kinase (JNK) pathway, linking stress signals to transcriptional outputs^[3]^[4]. Isoform-specific functions of JNK1, JNK2, and JNK3 modulate c-Jun activity in tissue- and cell-specific contexts, influencing apoptosis, inflammation, and neuroplasticity^[1]^[5]^[6]. In disease models, c-Jun contributes to pathological angiogenesis, rheumatoid arthritis, and neurodegeneration, where its inhibition reduces endothelial proliferation, metalloproteinase expression, and neuronal apoptosis^[7]^[8]^[9]^[10]^[11]^[6]. Compared with related Jun-family members, c-Jun exhibits distinct phosphorylation patterns and transcriptional targets, enabling isoform-specific experimental interventions^[6]^[12]. Pharmacological inhibitors targeting JNK or c-Jun itself, such as SP600125 or DNAzymes, demonstrate utility in blocking pro-apoptotic signaling, reducing inflammation, and modulating angiogenic pathways, supporting their research and therapeutic application^[7]^[8]^[10]^[6]. In cancer and viral models, c-Jun interacts with oncogenic pathways, including Bcl-2/Bcl-xL upregulation and FGF-2-mediated proliferation, highlighting its role in cell survival and transcriptional regulation^[2]^[13]. Collectively, c-Jun integrates stress, mitogenic, and inflammatory signals, serving as a critical target for isoform-specific modulation in experimental and disease contexts^[1]^[3]^[6]^[7].

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)
