    at STAGE
  • an N-terminal domain
  • a central basic region-leucine zipper domain
  • a putative consensus JNK docking-site
  • a corresponding phosphoacceptor site
  • a short non-conserved 4050-AAs segment between the DNA binding domain and the ligand binding domain (LBD), termed the C-terminal extension (CTE), playing a role as a binding site for co-activator proteins
  • mono polymer homomer , heteromer , dimer
    interspecies ortholog to rattus Jundp2
    ortholog to murine Jundm2
  • bZIP family
  • member of the AP-1 (activating protein-1) family of the basic leucine zipper transcription factors
  • CATEGORY regulatory , transcription factor
    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • involved in the regulation of transcription, DNA-dependent
  • inhibitory subunit of the differentiation regulatory factor (DRF) complex
  • may play an important role in the RANK-mediated signal transduction system, especially in osteoclast differentiation
  • acting as a repressor functionally associated with HDAC3 to inhibit DDIT3 transcription
  • cooperates with various proteins to mediate regulatory activity
  • inhibitor of acetylation of histones and contributes to the maintenance of chromatin structure
  • plays a key role as a repressor of adipocyte differentiation by regulating the expression of the gene for C/EBPdelta via inhibition of histone acetylation
  • progesterone receptor-interacting protein enhancing the transcriptional activity of the N-terminal domain and can act in a manner independent of the ligand binding domain AF2
  • role as a regulator of the progression of normal cells through the cell cycle
  • AP1 family transcription factor that regulates the epigenetic status of histones
  • controls bone homeostasis and antibacterial immunity by regulating osteoclast and neutrophil differentiation
  • JDP2 plays a critical role as a cofactor NFE2L2 and MAFK in the regulation of the antioxidants and production of reactive oxygen species (ROS)
  • typically suppresses gene transcription through multiple mechanisms and plays a dual role in multiple cellular processes, including cell differentiation and proliferation which is dependent on AP1 function
  • plays a role as a histone chaperone and participates in diverse processes, such as cell-cycle arrest, cell differentiation, apoptosis, senescence, and metastatic spread, and functions as an oncogene and anti-oncogene, and as a cellular reprogramming factor
  • specific role of JDP2 in cellular-stress regulation and prevention
  • CELLULAR PROCESS nucleotide, transcription, regulation
    a component
  • dimerizes with other AP-1 proteins such as activating transcription factor-2 (ATF2)
  • JDP2 is an integral component of the NFE2L2-MAFK complex and it modulates antioxidant and detoxification programs by acting via the antioxidant-responsive element (ARE)
    DNA binding
    small molecule
  • recruited to the promoter of the gene for cyclin-A2 (CCNA2) at the AP-1 site (transcription of the gene for CCNA2 appears to be a direct target of JDP2 in the suppression of cell proliferation)
  • association of HDAC3 and HDAC6 with JDP2 and ATF3 occurs via direct protein-protein interactions
  • ATF3 was an inhibitor of neutrophil differentiation and JDP2 directly suppresses its expression via inhibition of histone acetylation
  • JDP2 associates with NFE2L2 and MAFK (NFE2L2-MAFK) to increase the transcription of antioxidant response element-dependent genes
  • JDP2 bound directly to the ARE core sequence, associated with NFE2L2 and MAFK (NFE2L2-MAFK) via basic leucine zipper domains, and increased DNA-binding activity of the NFE2L2-MAFK complex to the ARE and the transcription of ARE-dependent genes
  • TBX3 plays an important role in osteoclastogenesis at least in part by regulating CSF1-dependent expression of JDP2
  • DCLK1 efficiently phosphorylates JDP2, a possible target in the nucleus, with the aid of histones
  • cell & other
    repressed by TP53 that significantly repressed the transcriptional activity of the JDP2 promoter
    Phosphorylated by on Thr148 by JNK (c-Jun N-terminal kinase) and MAPK14, although the functional role of its phosphorylation is targeting it for proteosomal degradation
