ID:ZEP3_HUMAN DESCRIPTION: RecName: Full=Transcription factor HIVEP3; AltName: Full=Human immunodeficiency virus type I enhancer-binding protein 3; AltName: Full=Kappa-B and V(D)J recombination signal sequences-binding protein; AltName: Full=Kappa-binding protein 1; Short=KBP-1; AltName: Full=Zinc finger protein ZAS3; FUNCTION: Plays a role of transcription factor; binds to recognition signal sequences (Rss heptamer) for somatic recombination of immunoglobulin and T-cell receptor gene segments; Binds also to the kappa-B motif of gene such as S100A4, involved in cell progression and differentiation. Kappa-B motif is a gene regulatory element found in promoters and enhancers of genes involved in immunity, inflammation, and growth and that responds to viral antigens, mitogens, and cytokines. Involvement of HIVEP3 in cell growth is strengthened by the fact that its down- regulation promotes cell cycle progression with ultimate formation of multinucleated giant cells. Strongly inhibits TNF-alpha-induced NF-kappa-B activation; Interferes with nuclear factor NF-kappa-B by several mechanisms: as transcription factor, by competing for Kappa-B motif and by repressing transcription in the nucleus; through a non transcriptional process, by inhibiting nuclear translocation of RELA by association with TRAF2, an adapter molecule in the tumor necrosis factor signaling, which blocks the formation of IKK complex. Interaction with TRAF proteins inhibits both NF-Kappa-B-mediated and c-Jun N-terminal kinase/JNK-mediated responses that include apoptosis and proinflammatory cytokine gene expression. Positively regulates the expression of IL2 in T-cell. Essential regulator of adult bone formation. SUBUNIT: Interacts with TRAF1 AND TRAF2 as well as with JUN. Forms a multimeric complex with RUNX2 and E3 ubiquitin ligase WWP1 (By similarity). SUBCELLULAR LOCATION: Cytoplasm (By similarity). Nucleus (By similarity). INDUCTION: By 12-O-tetradecanoylphorbol-13 acetate (TPA). DOMAIN: The ZAS2 domain binds DNA as dimers, tetramers, and multiple of tetramers and readily forms highly ordred DNA-protein structures (By similarity). PTM: Phosphorylated on threonine and serine residues (By similarity). SIMILARITY: Contains 5 C2H2-type zinc fingers. SEQUENCE CAUTION: Sequence=BAB13381.2; Type=Erroneous initiation;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
