Molecular cloning and functional characterization of a new Cap'n' collar family transcription factor Nrf3. (1/1416)

The NF-E2-binding sites or Maf recognition elements (MARE) are essential cis-acting elements in the regulatory regions of erythroid-specific genes recognized by the erythroid transcription factor NF-E2, composed of p45 and MafK. Recently, two p45-related factors Nrf1 and Nrf2 were isolated, and they are now collectively grouped as the Cap'n' collar (CNC) family. CNC factors bind to MARE through heterodimer formation with small Maf proteins. We report here the identification and characterization of a novel CNC factor, Nrf3, encoding a predicted 73-kDa protein with a basic region-leucine zipper domain highly homologous to those of other CNC proteins. In vitro and in vivo analyses showed that Nrf3 can heterodimerize with MafK and that this complex binds to the MARE in the chicken beta-globin enhancer and can activate transcription. Nrf3 mRNA is highly expressed in human placenta and B cell and monocyte lineage. Chromosomal localization of human Nrf3 is 7p14-15, which lies near the hoxA gene locus. As the genetic loci of p45, nrf1, and nrf2 have been mapped close to those of hoxC, hoxB, and hoxD, respectively, the present study strongly argues for the idea that a single ancestral gene for the CNC family members may have been localized near the ancestral Hox cluster and have diverged to give rise to four closely related CNC factors through chromosome duplication.  (+info)

Silencing of the Epstein-Barr virus latent membrane protein 1 gene by the Max-Mad1-mSin3A modulator of chromatin structure. (2/1416)

The tumor-associated latent membrane protein 1 (LMP1) gene in the Epstein-Barr virus (EBV) genome is activated by EBV-encoded proteins and cellular factors that are part of general signal transduction pathways. As previously demonstrated, the proximal region of the LMP1 promoter regulatory sequence (LRS) contains a negative cis element with a major role in EBNA2-mediated regulation of LMP1 gene expression in B cells. Here, we show that this silencing activity overlaps with a transcriptional enhancer in an LRS sequence that contains an E-box-homologous motif. Mutation of the putative repressor binding site relieved the repression both in a promoter-proximal context and in a complete LRS context, indicating a functional role of the repressor. Gel retardation assays showed that members of the basic helix-loop-helix transcription factor family, including Max, Mad1, USF, E12, and E47, and the corepressor mSin3A bound to the E-box-containing sequence. The enhancer activity correlated with the binding of USF. Moreover, the activity of the LMP1 promoter in reporter constructs was upregulated by overexpression of USF1 and USF2a, and the transactivation was inhibited by the concurrent expression of Max and Mad1. This suggests that Max-Mad1-mediated anchorage of a multiprotein complex including mSin3A and histone deacetylases to the E-box site constitutes the basis for the repression. Removal of acetyl moieties from histones H3 and H4 should result in a chromatin structure that is inaccessible to transcription factors. Accordingly, inhibition of deacetylase activity with trichostatin A induced expression of the endogenous LMP1 gene in EBV-transformed cells.  (+info)

Transcriptional repression of human hepatitis B virus genes by a bZIP family member, E4BP4. (3/1416)

Box alpha is an essential element of both the upstream regulatory sequence of the core promoter and the second enhancer, which positively regulate the transcription of human hepatitis B virus (HBV) genes. In this paper, we describe the cloning and characterization of a box alpha binding protein, E4BP4. E4BP4 is a bZIP type of transcription factor. Overexpression of E4BP4 represses the stimulating activity of box alpha in the upstream regulatory sequence of the core promoter and the second enhancer in differentiated human hepatoma cell lines. E4BP4 can also suppress the transcription of HBV genes and the production of HBV virions in a transient-transfection system that mimics the viral infection in vivo. Expression of an E4BP4 antisense transcript can, instead, elevate the transcription of the core promoter. A low abundance of E4BP4 protein and mRNA in differentiated human hepatoma cell lines is detected, and E4BP4 is not a major component of box alpha binding proteins in untransfected differentiated human hepatoma cell lines. C/EBPalpha and C/EBPbeta, in contrast, are major components of the box alpha binding activity present in nuclear extracts. E4BP4 has a stronger binding affinity towards box alpha than the endogenous box alpha binding activity present in nuclear extracts. Structure and function analysis of E4BP4 reveals that DNA binding activity is sufficient to confer the negative regulatory function of E4BP4. These results indicate that binding site occlusion is the mechanism whereby E4BP4 suppresses transcription in HBV.  (+info)

Two distinct interleukin-3-mediated signal pathways, Ras-NFIL3 (E4BP4) and Bcl-xL, regulate the survival of murine pro-B lymphocytes. (4/1416)

Hematopoietic cells require cytokine-initiated signals for survival as well as proliferation. The pathways that transduce these signals, ensuring timely regulation of cell fate genes, remain largely undefined. The NFIL3 (E4BP4) transcription factor, Bcl-xL, and constitutively active mutants of components in Ras signal transduction pathways have been identified as key regulation proteins affecting murine interleukin-3 (IL-3)-dependent cell survival. Here we show that expression of NFIL3 is regulated by oncogenic Ras mutants through both the Raf-mitogen-activated protein kinase and phosphatidylinositol 3-kinase pathways. NFIL3 inhibits apoptosis without affecting Bcl-xL expression. By contrast, Bcl-xL levels are regulated through the membrane proximal portion in the cytoplasmic domain of the receptor (betac chain), which is shared by IL-3 and granulocyte-macrophage colony-stimulating factor. Activation of either pathway alone is insufficient to ensure cell survival, indicating that multiple independent signal transduction pathways mediate the survival of developing B-lymphoid cells.  (+info)

Kaposi's sarcoma-associated herpesvirus (human herpesvirus-8) encodes a homologue of the Epstein-Barr virus bZip protein EB1. (5/1416)

Analysis of the recently completed genomic sequence of Kaposi's sarcoma-associated herpesvirus (human herpesvirus-8) revealed that ORF 50 encodes a protein with homology to the Epstein-Barr virus (EBV) transcription factor R. In this report, we show that ORF K8, contiguous to ORF 50, is interrupted by two introns and that the spliced RNA is translated into a bZip protein that has homology to the EBV transcription factor EB1. The newly characterized K8 protein forms homodimers but does not heterodimerize with other members of the bZip protein family.  (+info)

Multiple regulatory elements control the expression of the yeast ACR1 gene. (6/1416)

The ACR1 gene, encoding a succinate-fumarate transporter, is required by the yeast Saccharomyces cerevisiae for ethanol utilization. Accordingly, gene expression is induced by ethanol and repressed by glucose. Here, we investigated three carbon source response elements present in its promoter region. Specific deletions as well as functional analysis of the elements in a heterologous promoter confirmed their role in transcriptional regulation. Protein binding to carbon source response elements of the ICL1 promoter was competed by all three elements to various extents by the respective ACR1 sequences. In addition, two putative stress response promoter elements present in the ACR1 promoter were investigated in deletion analyses and shown to contribute to gene expression.  (+info)

A novel human DNA-binding protein with sequence similarity to a subfamily of redox proteins which is able to repress RNA-polymerase-III-driven transcription of the Alu-family retroposons in vitro. (7/1416)

In this study we identified a novel protein which may contribute to the transcriptional inactivity of Alu retroposons in vivo. A human cDNA clone encoding this protein (ACR1) was isolated from a human expression library using South-western screening with an Alu subfragment, implicated in the regulation of Alu in vitro transcription and interacting with a HeLa nuclear protein down-regulated in adenovirus-infected cells. Bacterially expressed ACR1 is demonstrated to inhibit RNA polymerase III (Pol III)-dependent Alu transcription in vitro but showed no repression of transcription of a tRNA gene or of a reporter gene under control of a Pol II promoter. ACR1 mRNA is also found to be down-regulated in adenovirus-infected HeLa cells, consistent with a possible repressor function of the protein in vivo. ACR1 is mainly (but not exclusively) located in cytoplasm and appears to be a member of a weakly characterized redox protein family having a central, highly conserved sequence motif, PGAFTPXCXXXXLP. One member of the family identified earlier as peroxisomal membrane protein (PMP)20 is known to interact in a sequence-specific manner with a yeast homolog of mammalian cyclosporin-A-binding protein cyclophilin, and mammalian cyclophilin A (an abundant ubiquitously expressed protein) is known to interact with human transcriptional repressor YY1, which is a major sequence-specific Alu-binding protein in human cells. It appears, therefore, that transcriptional silencing of Alu in vivo is a result of complex interactions of many proteins which bind to its Pol III promoter.  (+info)

Ubiquitination and degradation of ATF2 are dimerization dependent. (8/1416)

Ubiquitination and proteasome-dependent degradation are key determinants of the half-lives of many transcription factors. Homo- or heterodimerization of basic region-leucine zipper (bZIP) transcription factors is required for their transcriptional activities. Here we show that activating transcription factor 2 (ATF2) heterodimerization with specific bZIP proteins is an important determinant of the ubiquitination and proteasome-dependent degradation of ATF2. Depletion of c-Jun as one of the ATF2 heterodimer partners from the targeting proteins decreased the efficiency of ATF2 ubiquitination in vitro, whereas the addition of exogenously purified c-Jun restored it. Similarly, overexpression of c-Jun in 293T human embryo kidney cells increased ATF2 ubiquitination in vivo and reduced its half-life in a dose-dependent manner. Mutations of ATF2 that disrupt its dimerization inhibited ATF2 ubiquitination in vitro and in vivo. Conversely, removal of residues 150 to 248, as in a constitutively active ATF2 spliced form, enhanced ATF2 dimerization and transactivation, which coincided with increased ubiquitination and decreased stability. Our findings indicate the increased sensitivity of transcriptionally active dimers of ATF2 to ubiquitination and proteasome-dependent degradation. Based on these observations, we conclude that increased targeting of a transcriptionally active ATF2 form indicates the mechanism by which the magnitude and the duration of the cellular stress response are regulated.  (+info)

nitrogen-rich conditions. URS1-CYC1-Ub-X-lacZ reporters were expressed in mitotic repression machinery mutants (ume6Δ, rpd3Δ, sin3Δ, isw2Δ and itc1Δ) under nitrogen rich conditions. The data presented here from these experiments not only corroborates their known role in repression at URS1 but also suggested regulation at additional sites in the minimal CYC1 promoter. Deletion of Sin3p suggested independent repression function separable from Rpd3p. Isw2p also acts independently of Itc1p at sites other than URS1. We also show that pseudohyphal growth was stimulated by non-fermentable carbon sources in sporulation efficient SK1 genetic background. The data also indicates that stimulation of pseudohyphal growth by non-fermentable carbon sources does not require respiration function or functional mitochondrial RTG pathway. ...
Human Lymphotropic Virus Type 1 (HTLV-1) is a complex retrovirus that causes Adult T-cell Leukemia (ATL), an often-fatal form of cancer characterized by uncontrolled proliferation of infected CD4+ T-cells. The viral protein HTLV-1 basic leucine zipper factor (HBZ) has been proven as essential for HTLV-1 proliferation and is believed to contribute to progression to ATL and maintenance of the disease. HBZ functions as a transcriptional regulator. The knock-down of the hbz gene suppresses ATL proliferation, supporting that HBZ is essential for leukemogenesis. Recently, the basic leucine zipper transcription factor ATF-like 3 (BATF3) and interferon regulatory factor 4 (IRF4) were shown to help drive the ATL-specific transcription program. Both BATF3 and IRF4 promote T-cell differentiation and proliferation. HBZ was found to control BATF3 transcription by binding an enhancer region of the BATF3 gene. However, the molecular mechanism used by HBZ to control BATF3 transcription was not resolved. This ...
Soil salinity severely affects plant growth and agricultural productivity. AtbZIP24 encodes a bZIP transcription factor that is induced by salt stress in Ambidopsis thaliana but suppressed in the salt-tolerant relative Lobularia maritima. Transcriptional repression of AtbZIP24 using RNA interference improved salt tolerance in A. thaliana. Under non-stress growth conditions, transgenic A. thaliana lines with decreased AtbZIP24 expression activated the expression of stress-inducible genes involved in cytoplasmic ion homeostasis and osmotic adjustment: the Na+ transporter AtHKT1, the Na+/H+ antiporter AtSOS1, the aquaporin AtPIP2.1, and a glutamine synthetase. In addition, candidate target genes of AtbZIP24 with functions in plant growth and development were identified such as an argonaute (AGO1)-related protein and cyclophilin AtCYP19.

Background: Nitrogen and light are two major regulators of plant metabolism and development. While genes involved in the control of each of these signals have begun to be identified, regulators that integrate gene responses to nitrogen and light signals have yet to be determined. Here, we evaluate the role of bZIP1, a transcription factor involved in light and nitrogen sensing, by exposing wild-type (WT) and bZIP1 T-DNA null mutant plants to a combinatorial space of nitrogen (N) and light (L) treatment conditions and performing transcriptome analysis. We use ANOVA analysis combined with clustering and Boolean modeling, to evaluate the role of bZIP1 in mediating L and N signaling genome-wide.Results: This transcriptome analysis demonstrates that a mutation in the bZIP1 gene can alter the L and/or N-regulation of several gene clusters. More surprisingly, the bZIP1 mutation can also trigger N and/or L regulation of genes that are not normally controlled by these signals in WT plants. This analysis ...
Lateral organs formed by the shoot apical meristem (SAM) are separated from surrounding stem cells by regions of low growth called boundaries. Arabidopsis (Arabidopsis thaliana) BLADE-ON-PETIOLE1 (BOP1) and BOP2 represent a class of genes important for boundary patterning in land plants. Members of this family lack a DNA-binding domain and interact with TGACG-motif binding (TGA) basic Leu zipper (bZIP) transcription factors for recruitment to DNA. Here, we show that clade I bZIP transcription factors TGA1 and TGA4, previously associated with plant defense, are essential cofactors in BOP-dependent regulation of development. TGA1 and TGA4 are expressed at organ boundaries and function in the same genetic pathways as BOP1 and BOP2 required for SAM maintenance, flowering, and inflorescence architecture. Further, we show that clade I TGAs interact constitutively with BOP1 and BOP2, contributing to activation of ARABIDOPSIS THALIANA HOMEOBOX GENE1, which is needed for boundary establishment. These ...

Batf2 belongs to the AP-1 basic leucine zipper transcription factor (activating transcription factor) family proteins, composed of Batf, Batf2, and Batf3 (26-29, 35), with Batf2 having very limited functional information available. Batf family proteins do not have a DNA binding domain and bind to DNA indirectly with support of other transcription factors. In this study, we demonstrate that Batf2 is involved in gene regulation of IFN-γ-activated classical macrophages as well as LPS/TLR-induced macrophage stimulation. Batf2, most probably in complex with the transcription factor Irf1, induces important classical effector genes in macrophages, among them Tnf, Nos2, Ccl5, and Il12b for inflammatory responses against type 1 infectious diseases, such as M. tuberculosis.. Gene expression studies in IFN-γ-activated M1 and in TLR-stimulated macrophages revealed a strong induction of the transcription factor Batf2, which was not observed in unstimulated or IL-4-activated M2, and hence Batf2 can be ...
November 22, 2017. A research group at Lund University in Sweden has found that when the HLF (hepatic leukemia factor) gene -which is expressed in immature blood cells - does not shut down on time, we are unable to develop a functional long-term immune system. This could be a very early stage of leukemia.. Blood stem cells give rise to all of our blood cells: the red blood cells that transport oxygen, the platelets that enable blood coagulation, and our immune cells that protect us from infections. Immune cells can, in turn, be divided into two groups; one that consists of cells with a very short life expectancy and a natural but rather unspecific ability to counteract infections (myeloid cells), and another that, in contrast, consists of very long-lived cells (lymphocytes) that specialise in combatting specific bacteria and viruses.. The ability of blood stem cells to form all types of blood cells is a fundamental property that is also utilized in connection with bone marrow transplants. An ...

TY - JOUR. T1 - Electrostatic effects in DNA bending by GCN4 mutants. AU - Strauss-Soukup, Juliane K.. AU - Maher, L. James. PY - 1998/1/27. Y1 - 1998/1/27. N2 - DNA architecture has been shown to be important for cellular processes such as activation of transcription, recombination, and replication. Many proteins reconfigure the shape of duplex DNA upon binding. Previous experiments have shown that some members of the eukaryotic bZIP family of DNA binding proteins appear to bend DNA, while others do not. We are exploring the role of electrostatic effects in DNA bending by bZIP proteins. The yeast bZIP transcription factor GCN4 does not induce DNA bending in vitro. Previously we substituted basic residues for three neutral amino acids in GCN4 to produce a CJCN4 derivative that bends DNA by ~ 15°. This result is consistent with a model of induced DNA bending wherein excess positive charge in proximity to one face of the double helix neutralizes local phosphate diester anions resulting in a ...

To unravel the biological function of Cap1p in C. albicans, we deleted the CAP1 gene in strain CAI4 and analyzed the consequence of this deletion on (i) the level of expression of Cap1p transcriptional targets and (ii) the susceptibility of the cells to a variety of toxic compounds. On the one hand, we found that deletion of CAP1 has no effect on the basal transcription of the genes analyzed, although these genes were found to be Cap1p transcriptional targets, as shown by their upregulation in theCAP1-TR transformants (Fig. 4). This observation is consistent with what has been found in S. cerevisiae for Yap1p targets such as YCF1, GSH1, andTRX2, whose expression is not reduced in a yap1deletion strain under noninducing conditions (50, 56). Rather, Yap1p has been shown to be required for stress-induced transcriptional activation of its targets (50), a situation mimicked by elevated gene dosage (56) or by expression of Yap1p derivatives carrying an altered CRD (see below). On the other hand, we ...

The basic leucine zipper transcription factor ATF5 is overexpressed in many tumor types and interference with its expression or function inhibits cancer cell survival. As a potential therapeutic approach to exploit these findings, we created dominant-negative (DN) ATF5 forms lacking DNA-binding ability that retain the ATF5 leucine zipper, and thus associate with and sequester ATF5s requisite leucine zipper-binding partners. Preclinical studies with DN-ATF5, including a cell-penetrating form, show in vitro and in vivo efficacy in compromising cancer cell survival. However, DN-ATF5s targets, and particularly those required for tumor cell survival, have been unknown. We report that cells lacking ATF5 succumb to DN-ATF5, indicating that ATF5 itself is not DN-ATF5s obligate target. Unbiased pull-down assays coupled with mass spectrometry and immunoblotting revealed that DN-ATF5 associates in cells with the basic leucine zipper proteins CEBPB and CEBPD and coiled-coil protein CCDC6. Consistent with ...

According to the prediction of the involvement of bZIP transcription factors in the ER stress response, AtbZIP60 was identified by genome-wide screening based on genomic information on Arabidopsis. Tunicamycin and other reagents activating the ER stress response induced transcripts of AtbZIP60. From these results, we predicted that AtbZIP60 plays a role in the ER stress response. Because the expression profile of AtbZIP60 was close to that of BiP, induction of AtbZIP60 transcript was not considered to be the first trigger of activation for BiP expression. Instead, it was assumed that a conformational change of AtbZIP60 activates the expression of chaperone genes, such as BiP. This prediction was based on the fact that AtbZIP60 contains a putative TMD like that of ATF6 in mammalian cells. Specifically, it was hypothesized that AtbZIP60 is converted to a soluble form by ER stress and becomes localized to the nucleus, resulting in the activation of chaperone genes. Indeed, a truncated form of ...

The physiological roles of the mitochondrial transcription termination factor (mTERF) family are poorly understood. MTERF and its homologues influence transcriptional readthrough in vitro, but the extent to which they regulate mitochondrial RNA levels in vivo is unclear. In addition, MTERF was previously shown to promote replication pausing. To test their roles in mtDNA metabolism, we created cell-lines inducibly expressing epitope-tagged versions of two members of the mTERF family, MTERFD1 and MTERFD3, as well as shRNA constructs targeted at each. We confirmed mitochondrial targeting and lack of sequence-specific DNA binding for both factors. Over-expression of epitope-tagged MTERFD1 or MTERFD3 resulted in modest mtDNA copy-number depletion and an accumulation of specific mtDNA replication intermediates indicating an impairment of the terminal steps of replication. These findings further implicate the mTERF family in restraining replication fork progression and support the idea that they ...

G-protein coupled receptor kinase 1 (Grk1) is essential for light-activated opsin phosphorylation in phototransduction shutoff, and genetic defects cause Oguchis disease, a form of Retinitis Pigmentosa (RP). To elucidate the recovery function of cone pigments, we combined Grk1-/- murine knockouts with the Neural retina leucine zipper (Nrl-/-), which have an enhanced S-cone phenotype. We observed that with increasing age and independent of light, the retinas of Nrl-/-Grk1-/- when compared to Nrl-/- developed progressive cone degeneration and decreased cone protein expression. The degeneration initially occurs in the central inferior quadrant and spreads with retinal pigment epithelia (RPE) atrophy. Endothelial cell specific immunohistochemistry and fluorescein angiography (FA) revealed progressive changes in retinal neovascularization in the Nrl-/-Grk1-/- at 1 month of age, prior to the onset of significant cone functional deficits and ONL thinning. Vascular Endothelial Growth Factor (VEGF) ...

The Myc/Max/Mad network comprises a group of transcription factors that co-interact to regulate gene-specific transcriptional activation or repression. This gene encodes a protein member of the Myc/Max/Mad network. This protein has a basic-Helix-Loop-Helix-zipper domain (bHLHzip) with which it binds the canonical DNA sequence CANNTG, known as the E box, following heterodimerization with Max proteins. This protein is a transcriptional repressor and an antagonist of Myc-dependent transcriptional activation and cell growth. This protein represses transcription by binding to DNA and recruiting Sin3 corepressor proteins through its N-terminal Sin3-interaction domain [1][4] ...
