Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes. (King & Stansfield, A Dictionary of Genetics, 4th ed)

Inhibition of NFkappaB by methyl chlorogenate from Eriobotrya japonica. (1/5043)

Methylchlorogenic acid (MC) is one of the main components in the leaves of Eriobotrya japonica. We previously reported that MC is the most potent antioxidant among several components of Eriobotrya japonica, and its antioxidant activity is stronger than that of chlorogenic acid. Antioxidants are expected to inhibit redox-sensitive NFkappaB activation since NFkappaB is readily influenced by cellular oxidative state. Based on these findings, in vivo experiments with MC were conducted to determine its ability to downregulate the NFkappaB activation in mouse liver. Results clearly showed that MC is a potent suppressor of BHP-induced NFkappaB activation. We observed a significant reduction by MC on BHP-induced translocation of p65 subunit of NFkappaB. This may be due to formation of p50/p65 heterodimer, which is mainly inducible NFkappaB. MC slightly blocked the BHP-induced IkappaB alpha degradation. There is a possibility of IkappaB alpha resynthesis via activated NFkappaB during a 5 h waiting period following BHP injection. The present results suggest that MC may inhibit NFkappaB activation, exhibiting its ability to downregulate the NFkappaB-dependent gene expression. Thus, it can be expected that MC may have potential for therapeutic intervention on various NFkappaB-dependent pathological conditions such as inflammatory or possibly mutagenic processes.  (+info)

Activation of protein kinase C induces nuclear translocation of RFX1 and down-regulates c-myc via an intron 1 X box in undifferentiated leukemia HL-60 cells. (2/5043)

Treatment of human promyelocytic leukemia cells (HL-60) with phorbol 12-myristate 13-acetate (PMA) is known to decrease c-myc mRNA by blocking transcription elongation at sites near the first exon/intron border. Treatment of HL-60 cells with either PMA or bryostatin 1, which acutely activates protein kinase C (PKC), decreased the levels of myc mRNA and Myc protein. The inhibition of Myc synthesis accounted for the drop in Myc protein, because PMA treatment had no effect on Myc turnover. Treatment with PMA or bryostatin 1 increased nuclear protein binding to MIE1, a c-myc intron 1 element that defines an RFX1-binding X box. RFX1 antiserum supershifted MIE1-protein complexes. Increased MIE1 binding was independent of protein synthesis and abolished by a selective PKC inhibitor, which also prevented the effect of PMA on myc mRNA and protein levels and Myc synthesis. PMA treatment increased RFX1 in the nuclear fraction and decreased it in the cytosol without affecting total RFX1. Transfection of HL-60 cells with myc reporter gene constructs showed that the RFX1-binding X box was required for the down-regulation of reporter gene expression by PMA. These findings suggest that nuclear translocation and binding of RFX1 to the X box cause the down-regulation of myc expression, which follows acute PKC activation in undifferentiated HL-60 cells.  (+info)

Active aminoacyl-tRNA synthetases are present in nuclei as a high molecular weight multienzyme complex. (3/5043)

Recent studies suggest that aminoacylation of tRNA may play an important role in the transport of these molecules from the nucleus to the cytoplasm. However, there is almost no information regarding the status of active aminoacyl-tRNA synthetases within the nuclei of eukaryotic cells. Here we show that at least 13 active aminoacyl-tRNA synthetases are present in purified nuclei of both Chinese hamster ovary and rabbit kidney cells, although their steady-state levels represent only a small percentage of those found in the cytoplasm. Most interestingly, all the nuclear aminoacyl-tRNA synthetases examined can be isolated as part of a multienzyme complex that is more stable, and consequently larger, than the comparable complex isolated from the cytoplasm. These data directly demonstrate the presence of active aminoacyl-tRNA synthetases in mammalian cell nuclei. Moreover, their unexpected structural organization raises important questions about the functional significance of these multienzyme complexes and whether they might play a more direct role in nuclear to cytoplasmic transport of tRNAs.  (+info)

Maternally controlled (beta)-catenin-mediated signaling is required for organizer formation in the zebrafish. (4/5043)

We have identified and characterized a zebrafish recessive maternal effect mutant, ichabod, that results in severe anterior and dorsal defects during early development. The ichabod mutation is almost completely penetrant, but exhibits variable expressivity. All mutant embryos fail to form a normal embryonic shield; most fail to form a head and notochord and have excessive development of ventral tail fin tissue and blood. Abnormal dorsal patterning can first be observed at 3.5 hpf by the lack of nuclear accumulation of (beta)-catenin in the dorsal yolk syncytial layer, which also fails to express bozozok/dharma/nieuwkoid and znr2/ndr1/squint. At the onset of gastrulation, deficiencies in expression of dorsal markers and expansion of expression of markers of ventral tissues indicate a dramatic alteration of dorsoventral identity. Injection of (beta)-catenin RNA markedly dorsalized ichabod embryos and often completely rescued the phenotype, but no measurable dorsalization was obtained with RNAs encoding upstream Wnt pathway components. In contrast, dorsalization was obtained when RNAs encoding either Bozozok/Dharma/Nieuwkoid or Znr2/Ndr1/Squint were injected. Moreover, injection of (beta)-catenin RNA into ichabod embryos resulted in activation of expression of these two genes, which could also activate each other. RNA injection experiments strongly suggest that the component affected by the ichabod mutation acts on a step affecting (beta)-catenin nuclear localization that is independent of regulation of (beta)-catenin stability. This work demonstrates that a maternal gene controlling localization of (beta)-catenin in dorsal nuclei is necessary for dorsal yolk syncytial layer gene activity and formation of the organizer in the zebrafish.  (+info)

Nuclear translocation of mismatch repair proteins MSH2 and MSH6 as a response of cells to alkylating agents. (5/5043)

Mammalian mismatch repair has been implicated in mismatch correction, the prevention of mutagenesis and cancer, and the induction of genotoxicity and apoptosis. Here, we show that treatment of cells specifically with agents inducing O(6)-methylguanine in DNA, such as N-methyl-N'-nitro-N-nitrosoguanidine and N-methyl-N-nitrosourea, elevates the level of MSH2 and MSH6 and increases GT mismatch binding activity in the nucleus. This inducible response occurs immediately after alkylation, is long-lasting and dose-dependent, and results from translocation of the preformed MutSalpha complex (composed of MSH2 and MSH6) from the cytoplasm into the nucleus. It is not caused by an increase in MSH2 gene activity. Cells expressing the DNA repair protein O(6)-methylguanine-DNA methyltransferase (MGMT), thus having the ability to repair O(6)-methylguanine, showed no translocation of MutSalpha, whereas inhibition of MGMT by O(6)-benzylguanine provoked the translocation. The results demonstrate that O(6)-methylguanine lesions are involved in triggering nuclear accumulation of MSH2 and MSH6. The finding that treatment of cells with O(6)-methylguanine-generating mutagens results in an increase of MutSalpha and GT binding activity in the nucleus indicates a novel type of genotoxic stress response.  (+info)

Three leucine-rich sequences and the N-terminal region of double-stranded RNA-activated protein kinase (PKR) are responsible for its cytoplasmic localization. (6/5043)

The double-stranded RNA-activated-protein kinase PKR was originally identified as a ribosomal protein that regulates protein synthesis at the translational level. While PKR locates predominantly to the cytoplasm, nuclear or nucleolar species of PKR have been detected. Here, we demonstrate that PKR possesses three leucine-rich sequences resembling nuclear export signals (NESs). Enhanced green fluorescent protein (EGFP) fused to one of these sequences and transfected in COS-1 cells exhibited predominant cytoplasmic staining, which was abrogated by a leucine to alanine substitution. In addition, Leptomycin B (LMB), an inhibitor of NES-mediated nuclear export, inhibited the cytoplasmic localization of EGFP-NES, indicating the potential activity of these stretches as NESs. Although EGFP fused to a PKR with three NES mutations still located to the cytoplasm, an additional N-terminal deletion impaired the cytoplasmic predominance, suggesting that the N-terminal region is also required for localization. These results suggest that the cytoplasmic localization of PKR is regulated by NESs as well as the N-terminal sequence.  (+info)

Evidence that the beta-catenin nuclear translocation assay allows for measuring presenilin 1 dysfunction. (7/5043)

BACKGROUND: Mutations in the presenilin (PSEN) genes are responsible for the majority of early-onset Alzheimer disease (AD) cases. PSEN1 is a component of a high molecular weight, endoplasmic reticulum, membrane-bound protein complex, including beta-catenin. Pathogenic PSEN1 mutations were demonstrated to have an effect on beta-catenin and glycogen synthase kinase-3beta(GSK-3beta), two members of the wingless Wnt pathway. The nuclear translocation and the stability of beta-catenin, and the interaction between GSK3beta and PSEN1 were influenced. MATERIALS AND METHODS: Stably transfected human embryonic kidney (HEK) 293 cells overexpressing wild-type (wt) and mutant (mt) PSEN1, treated with and without LiCl, were used to isolate cytoplasmic and nuclear fractions. By Western blot analysis, endogenous beta-catenin levels were examined. By analyzing cytosolic fractions of PSEN1, transfected and nontransfected HEK 293 cells, and total brain extracts of AD patients and controls, we evaluated the effect of PSEN1 overexpression on beta-catenin stability. Finally, we analyzed the effect of pathogenic PSEN1 mutations on the interaction between PSEN1 and GSK3beta by co-immunoprecipitation experiments. RESULTS: We report reduced nuclear translocation of beta-catenin in cells stably expressing I143T, G384A, and T113-114ins PSEN1. The G384A PSEN1 mutation showed a similar pronounced effect on nuclear translocation of beta-catenin, as reported for processing of amyloid precursor protein (APP) into amyloid beta(Abeta). Overexpression of PSEN1 and the presence of pathogenic mutations in PSEN1 had no significant effect on the stability of beta-catenin. Nonspecific binding of overexpressed PSEN1 to endogenous GSK3beta was observed when GSK3beta was immunoprecipitated. Immunoprecipitation of PSEN1 in cells overexpressing PSEN1 and in native cells, however, did not result in co-immunoprecipitation of endogenous GSK3beta. CONCLUSION: Our results further establish the nuclear translocation assay of beta-catenin as an adequate alternative for traditional Abeta measurement to evaluate the effect of PSEN1 mutations on biochemical processes. We detected no significant effect of overexpressed wt or mt PSEN1 on the stability of beta-catenin. Finally, co-immunoprecipitation between PSEN1 and GSK3beta was not observed in our experimental setup.  (+info)

Bradykinin activates the Janus-activated kinase/signal transducers and activators of transcription (JAK/STAT) pathway in vascular endothelial cells: localization of JAK/STAT signalling proteins in plasmalemmal caveolae. (8/5043)

Bradykinin (BK) is an important physiological regulator of endothelial cell function. In the present study, we have examined the role of the Janus-activated kinase (JAK)/signal transducers and activators of transcription (STAT) pathway in endothelial signal transduction through the BK B2 receptor (B2R). In cultured bovine aortic endothelial cells (BAECs), BK activates Tyk2 of the JAK family of tyrosine kinases. Activation results in the tyrosine phosphorylation and subsequent nuclear translocation of STAT3. BK also activates the mitogen-activated p44 and p42 protein kinases, resulting in STAT3 serine phosphorylation. Furthermore, Tyk2 and STAT3 form a complex with the B2R in response to BK stimulation. Under basal conditions, Tyk2, STAT3 and the B2R are localized either partially or entirely in endothelial plasmalemmal caveolae. Following BK stimulation of BAECs, however, the B2R and STAT3 are translocated out of caveolae. Taken together, these data suggest that BK activates the JAK/STAT pathway in endothelial cells and that JAK/STAT signalling proteins are localized in endothelial caveolae. Moreover, caveolar localization of the B2R and STAT3 appears to be regulated in an agonist-dependent manner.  (+info)

TY - JOUR. T1 - Influenza A virus NS1 protein promotes efficient nuclear export of unspliced viral M1 mRNA. AU - Pereira, Carina F.. AU - Read, Eliot K. C.. AU - Wise, Helen M.. AU - Amorim, Maria J.. AU - Digard, Paul. PY - 2017/8. Y1 - 2017/8. N2 - Influenza A virus mRNAs are transcribed by the viral RNA-dependent RNA polymerase in the cell nucleus before being exported to the cytoplasm for translation. Segment 7 produces two major transcripts: an unspliced mRNA that encodes the M1 matrix protein and a spliced transcript that encodes the M2 ion channel. Export of both mRNAs is dependent on the cellular NXF1/TAP pathway, but it is unclear how they are recruited to the export machinery or how the introncontaining but unspliced M1 mRNA bypasses the normal quality-control checkpoints. Using fluorescent in situ hybridization to monitor segment 7 mRNA localization, we found that cytoplasmic accumulation of unspliced M1 mRNA was inefficient in the absence of NS1, both in the context of segment 7 RNPs ...

Transport of macromolecules into and out of the nucleus is generally effected by targeting signals that are recognized by specific members of the importin/exportin transport receptor family. The latter mediate passage through the nuclear envelope-embedded nuclear pore complexes (NPCs) by conferring interaction with NPC constituents, as well as with other components of the nuclear transport machinery, including the guanine nucleotide-binding protein Ran. Importantly, nuclear transport is regulated at multiple levels via a diverse range of mechanisms, such as the modulation of the accessibility and affinity of target signal recognition by importins/exportins, with phosphorylation/dephosphorylation as a major mechanism. Alteration of the level of the expression of components of the nuclear transport machinery also appears to be a key determinant of transport efficiency, having central importance in development, differentiation and transformation ...

The results described in this paper indicate that HIV unspliced RNA export and Gag trafficking to the plasma membrane are linked. By simply changing the RNA export element from the RRE to 4 × CTE, we can restore Gag assembly and budding in murine cells (Figures 3 and 5). To explain how a pretranslational event, RNA export, could modulate a post‐translational event, membrane trafficking, we hypothesize that HIV RNA is marked at (or by) nuclear export such that the cytosolic fate of the encoded Gag is predetermined. Based on our findings, both the RRE/Rev/Crm1 and 4 × CTE/NXF1 nuclear export pathways successfully mark unspliced gag‐pol mRNA in human cells and promote proper assembly. However, in murine cells, marking through the action of RRE/Rev/Crm1 is defective and HIV assembly is inhibited. Possibilities for the mark include the structure of the mRNA itself or proteins that comprise the mRNP; these could be added or removed as the export complex is formed, as it transits the NPC, ...
In this study, we have shown that (a) although 14-3-3 proteins are predominantly localized in the cytoplasm, a large number of ligands are localized within the nucleus; (b) endogenous 14-3-3, fully competent to bind ligands, can be trapped in the nucleus by inhibiting Crm1-dependent nuclear export with LMB; (c) the leucine-rich putative NES sequence in 14-3-3, despite its structural homology to known NES sequences (Rittinger et al., 1999) and its ability to function as an NES in isolation when fused to GFP (unpublished data), functions primarily in phosphoprotein binding and not as an NES in the context of the intact 14-3-3 molecule; (d) a mutant 14-3-3, which cannot bind to ligands, homes to the nucleus; (e) the nuclear 14-3-3 ligand FKHRL1 is phosphorylated at its major 14-3-3 binding site within the nucleus before its export into the cytoplasm; and (f) at least for FKHRL1, rapid export from the nucleus to the cytoplasm requires both phosphorylation/14-3-3 binding and NES sequences within the ...
Although there appears to be some discrepancy between these new findings and our previous reports that importins are dispensable for the nuclear import of Smads, these observations can be reconciled (Xu et al., 2002, 2003). Our present and previous studies, based on different approaches, may have revealed different nuclear import mechanisms used by basal and activated Smads to enter the nucleus. There are important differences comparing Smads import with or without TGF-β stimulation. Unphosphorylated Smads are monomers, but phosphorylated Smads are assembled into complexes with Smad4 and are thus much larger in size (Wu et al., 2001; Chacko et al., 2004). Moreover, as phospho-Smads accumulate in the nucleus they have to move across the nuclear pore against an ascending concentration gradient of Smads already in the nucleus, whereas unphosphorylated Smads never reach a higher concentration in the nucleus than in the cytoplasm. Thus, importing phospho-Smad complexes and unphosphorylated Smad ...
The nuclear export of Foxo can be inhibited by LMB (Fig. 11), which binds to and thus removes the availability of CRM1 for nuclear export. In the presence of a fully blocking concentration of LMB, any Foxo that enters the nucleus is unable to leave and becomes trapped in the nucleus. Inhibition of nuclear export via LMB thus provides a powerful tool for measuring the rate of unidirectional nuclear influx and for calculating its rate constant of cytoplasmic efflux. The change in the rate constant for unidirectional efflux out of the cytoplasm due to treatment with phosphorylation modulators demonstrates the importance of cytoplasmic phosphorylation/dephosphorylation of Foxo1 in regulation of its rate of cytoplasmic efflux (Figs. 6, 9, and 10). Furthermore, the increase in the rate of nuclear influx that resulted from staurosporine addition in the presence of LMB (Fig. 9A) indicates that the nuclear import machinery is not saturated at the level of expression of Foxo1-GFP employed under our ...
There are two types of protein transport processes evident during nucleocytoplasmic exchange being nuclear import and export. The majority of proteins are synthesised in the cytoplasm, therefore nuclear import is a dominant form of protein transportation into the nucleus. Moreover, nuclear export is equally crucial in nucleocytoplasmic transport during later parts of protein processing to return products into the cytoplasm such as tRNA, rRNA and mRNA. In addition, some proteins may be required to move across the NE several times to be fully developed into a functional subunit. In comparison to the nucleus, after importing proteins into the rough endoplasmic reticulum (rER), they cannot exit due to the absence of specific signals to initiate transportation back across the plasma membrane to the cytoplasm. Nucleus therefore has a unique means of transportation, having equally important import and export process. Most protein carriers involving NPCs are the members karyopherins family. This ...
In this study, we have reported a means to specifically prevent p42/p44MAPK nuclear translocation without affecting its activation. Different methods can theoretically be used to achieve the blockage of MAPK nuclear translocation. The one we employed here was to create an artificial anchor for MAPK based on two criteria: a specific interaction with MAPK and a cytoplasmic localization. Several proteins could possibly fulfil the criteria to create a cytoplasmic anchor for MAPK. For instance, the activator of MAPK, MKK1, is a cytoplasmic protein that also binds specifically to MAPK (Bardwell et al., 1996; Fukuda et al., 1997) and has therefore been proposed to play the role of an MAPK anchor in vivo (Fukuda et al., 1997). Moreover expression of MKK1 in Xenopus has been shown to impair MAPK nuclear translocation (Fukuda et al., 1997). However, in our fibroblast CCL39 cell line, the ability of MKK1 expression to prevent MAPK nuclear translocation was much weaker than that of inactive MKP‐3. This ...
Hey-mutant mouse hearts at embryonic day E14.5 were shown to react to the knock out of Hey2 with several up-regualted genes. This up-regulation is due to the lack of Hey2 and cannot be explained by the structural changes in heart morphology as shown using control animals. Part of the gene regulation was further validated using in situ hybridization. Hey1 was located to the nucleus in immunofluorescence experiments. However, experiments on protein level showed also amount of Hey1 within the cytoplasm. The nuclear localization of Hey1 was unchanged during all cell cycle phases as well as when CaMKII was co-expressed or other cellular pathways were inhibited or stimulated. Hey1 does not seem to interact with the nuclear transport proteins importin-alpha and -beta, therefore it still needs to be elucidated how Hey1 is transported into the nucleus ...
We are interested in transport processes and in photosynthesis. Within the realm of photosynthesis we are mainly concerned with dynamic processes that accompany the life cycle of the thylakoid network, including its response to different stresses and its formation and dismantling.

The cowpox virus-encoded anti-apoptotic protein cytokine response modifier A (CrmA) is a member of the serpin family that specifically inhibits the cellular proteins caspase 1, caspase 8 and granzyme B. In this study, we have used Flag- and yellow fluorescent protein (YFP)-tagged versions of CrmA to investigate the mechanisms that regulate its subcellular localization. We show that CrmA can actively enter and exit the nucleus and we demonstrate the role of the nuclear export receptor CRM1 in this shuttling process. CrmA contains a novel leucine-rich nuclear export signal (NES) that is functionally conserved in the anti-apoptotic cellular serpin PI-9. Besides this leucine-rich export signal, additional sequences mapping to a 103-amino-acid region flanking the NES contribute to the CRM1-dependent nuclear export of CrmA. Although YFP-tagged CrmA is primarily located in the cytoplasm, shifting its localization to be predominantly nuclear by fusion of a heterologous nuclear localization signal did ...

Recent investigations have elucidated several molecular pathways for the nuclear import and export of proteins (Kau and Silver, 2003; Weis, 2003) across transport passageways or nuclear pore complexes (NPCs) (Dreger, 2003). The NPC is a large (125 MDa) multimeric protein structure that perforates the nuclear envelope and channels proteins greater than 60 kDa into or out of the nucleus. The constituents of the NPC have been described in yeast (Rout et al., 2000) and mammalian cells (Cronshaw et al., 2002). Proteins targeted for receptor-mediated transport across the NPC must either contain a nuclear localization signal (NLS) or a nuclear export signal (NES). Protein NLS are typically short clusters of basic amino acids, often preceded by an acidic amino acid or proline residue. However, a NLS may also consist of bipartite clusters of basic amino acids separated by a spacer region of approximately ten amino acids, often flanked by a neutral or acidic amino acid. Previously described NLSs are ...
The nuclear export receptor Crm1 cooperatively binds its HIV Rev-RRE cargo as a dimer using a species-specific interface that supports viral replication by enhancing nuclear export of HIV RNA.
Author Summary Herpesviruses hijack cellular components to enhance viral gene expression. This is particularly important for the efficient nuclear export of herpesvirus intronless mRNAs to allow the production of viral proteins. We have previously demonstrated that Kaposis sarcoma-associated herpesvirus encodes a conserved protein, ORF57, which recruits essential cellular mRNA export proteins onto the viral intronless mRNAs to form an export competent viral ribonucleoprotein particle. Specifically, we have shown that ORF57 interacts directly with the cellular export adaptor protein, Aly, to recruit other cellular mRNA export proteins. Surprisingly however, depletion of Aly has a limited effect on both cellular and viral mRNA nuclear export levels, suggesting a degree of redundancy in the export pathways and the existence of other export adaptor proteins. Here we have identified a novel interaction between ORF57 and a second export adaptor protein, UIF. We show for the first time that the ORF57-UIF
Nucleophosmin (NPM) is a nucleocytoplasmic shuttling protein, normally enriched in nucleoli, that performs several activities related to cell growth. NPM mutations are characteristic of a subtype of acute myeloid leukemia (AML), where mutant NPM seems to play an oncogenic role. AML-associated NPM mutants exhibit altered subcellular traffic, being aberrantly located in the cytoplasm of leukoblasts. Exacerbated export of AML variants of NPM is mediated by the nuclear export receptor CRM1, and due, in part, to a mutationally acquired novel nuclear export signal (NES). To gain insight on the molecular basis of NPM transport in physiological and pathological conditions, we have evaluated the export efficiency of NPM in cells, and present new data indicating that, in normal conditions, wild type NPM is weakly exported by CRM1. On the other hand, we have found that AML-associated NPM mutants efficiently form complexes with CRM1HA (a mutant CRM1 with higher affinity for NESs), and we have quantitatively ...
During gene expression, RNA export factors are mainly known for driving nucleo-cytoplasmic transport. While early studies suggested that the exon junction complex (EJC) provides a binding platform for them, subsequent work proposed that they are only recruited by the cap binding complex to the 5 end of RNAs, as part of TREX. Using iCLIP, we show that the export receptor Nxf1 and two TREX subunits, Alyref and Chtop, are recruited to the whole mRNA co-transcriptionally via splicing but before 3 end processing. Consequently, Alyref alters splicing decisions and Chtop regulates alternative polyadenylation. Alyref is recruited to the 5 end of RNAs by CBC, and our data reveal subsequent binding to RNAs near EJCs. We demonstrate that eIF4A3 stimulates Alyref deposition not only on spliced RNAs close to EJC sites but also on single-exon transcripts. Our study reveals mechanistic insights into the co-transcriptional recruitment of mRNA export factors and how this shapes the human transcriptome.
It is an interesting phenomenon that a significant number of signaling molecules including p65 NF-κB, IκBα, Smad proteins and many others contain both nuclear localization and nuclear export sequences that counteract each other (Arenzana-Seisdedos et al., 1997; Gama-Carvalho and Carmo-Fonseca, 2001; Harhaj and Sun, 1999; Huang et al., 2000; Johnson et al., 1999; Reguly and Wrana, 2003). Signaling molecules such as transcription factors, which have roles both in the nucleus and in the cytosol, clearly require nuclear import and nuclear export mechanisms. However, more and more proteins without an obvious nuclear function are being found to shuttle between cytosol and nucleus (Gama-Carvalho and Carmo-Fonseca, 2001). Most of these proteins contain both NLS and NES domains, raising the question of how these opposing localization mechanisms are balanced and dynamically regulated. Several possibilities appear significant for regulating the equilibrium between counteracting localization signals. ...
Our results define a bipartite NLS that is integrated within the DNA-recognition region of IRF3. We mapped the NLS of IRF3 to aa 64-130, partially overlapping with the DBD. Basic amino acids KR77/78 and RK86/87 are required for efficient nuclear import of IRF3. Significantly, we demonstrate that the NLS of IRF3 also plays an important role in the DNA-binding activity.. The IRF family contains nine mammalian members (IRF1, IRF2, IRF3, IRF4, IRF5, IRF6, IRF7, IRF8, and IRF9), which are most conserved in their DBD. IRF1 and IRF2, which are closely related to each other, contain a conserved NLS located immediately C-terminal to the DBD, involving aa 120-138 (33). IRF4, IRF8, and IRF9 are highly conserved with each other and use the homologous NLS (aa 66-85) to direct their accumulation in the nucleus (34). Interestingly, IRF5 contains two monopartite consensus NLSs, a N-terminal NLS and a C-terminal NLS (35). Our study, together with previous reports, demonstrated that the NLSs of IRFs are generally ...
TY - JOUR. T1 - Nuclear import and export signals are essential for proper cellular trafficking and function of ZIC3. AU - Bedard, James E J. AU - Purnell, Jennifer D.. AU - Ware, Stephanie. PY - 2007/1/15. Y1 - 2007/1/15. N2 - Missense, frameshift and nonsense mutations in the zinc finger transcription factor ZIC3 cause heterotaxy as well as isolated congenital heart disease. Previously, we developed transactivation and subcellular localization assays to test the function of ZIC3 point mutations. Aberrant cytoplasmic localization suggested that the pathogenesis of ZIC3 mutations results, at least in part, from failure of appropriate cellular trafficking. To further investigate this hypothesis, the nucleocytoplasmic shuttling properties of ZIC3 have been examined. Subcellular localization assays designed to span the entire open-reading frame of wild-type and mutant ZIC3 proteins identified the presence of nucleocytoplasmic transport signals. ZIC3 domain mapping indicates that a relatively large ...
Combining with a nuclear export signal (NES) to mediate transport of the NES-containing protein through the nuclear pore to the cytoplasm.
In eukaryotic cells, pre-mRNAs undergo extensive processing in the nucleus prior to export. Processing is subject to a quality-control mechanism that retains improperly processed transcripts at or near sites of transcription. A poly(A) tail added by the normal 3′-processing machinery is necessary but not sufficient for export. Retention depends on the exosome. In this study, we identify the poly(A)-binding protein, Pab1, and the poly(A) nuclease, PAN, as important factors that couple 3′ processing to export. Pab1 contains a nonessential leucine-rich nuclear export signal and shuttles between the nucleus and the cytoplasm. It can exit the nucleus either as cargo of exportin 1 or bound to mRNA. Pab1 is essential but several bypass suppressors have been identified. Deletion of PAB1 from these bypass suppressor strains results in exosome-dependent retention at sites of transcription. Retention is also seen in cells lacking PAN, which Pab1 is thought to recruit and which may be responsible for ...
Activation of mitogen-activated protein kinases (MAPKs) and MAPK kinases (MEKs) leads to their translocation from the cytoplasm to the nucleus. Once the transduced signal has abated, the kinases shuttle back to the cytoplasm. However, MAPKs do not appear to have nuclear export signal (NES) motifs coded within their amino acid sequences. Adachi et al. resolve this enigma by showing that MAPK binds to MEK in the nucleus, and both utilize the NES motif found on MEK to relocalize to the cytoplasm. The nuclear export of MAPK was blocked by the specific NES inhibitor leptomycin B. Also, when injected into the nucleus, MAPK relocalized to the cytoplasm with coinjected MEK, but not with a MEK mutant in which the NES was disrupted. Finally, nuclear injection of a protein fragment that includes the MAPK-binding site on MEK decreased MAPK export. Thus, transport of MAPK from the nucleus to the cytoplasm appears to require association of MAPK with MEK.. Adachi, M., Fukuda, M., and Nishida, E. (2000) Nuclear ...

Required for pre-mRNA splicing. Can also modulate alternative splicing in vitro. Represses the splicing of MAPT/Tau exon 10. May function as export adapter involved in mRNA nuclear export such as of histone H2A. Binds mRNA which is thought to be transferred to the NXF1-NXT1 heterodimer for export (TAP/NXF1 pathway); enhances NXF1-NXT1 RNA-binding activity. RNA-binding is semi-sequence specific.
