Newly assembled snRNPs associate with coiled bodies before speckles, suggesting a nuclear snRNP maturation pathway. (1/196)

BACKGROUND: Small nuclear ribonucleoproteins (snRNPs), which are essential components of the mRNA splicing machinery, comprise small nuclear RNAs, each complexed with a set of proteins. An early event in the maturation of snRNPs is the binding of the core proteins - the Sm proteins - to snRNAs in the cytoplasm followed by nuclear import. Immunolabelling with antibodies against Sm proteins shows that splicing snRNPs have a complex steady-state localisation within the nucleus, the result of the association of snRNPs with several distinct subnuclear structures. These include speckles, coiled bodies and nucleoli, in addition to a diffuse nucleoplasmic compartment. The reasons for snRNP accumulation in these different structures are unclear. RESULTS: When mammalian cells were microinjected with plasmids encoding the Sm proteins B, D1 and E, each tagged with either the green fluorescent protein (GFP) or yellow-shifted GFP (YFP), a pulse of expression of the tagged proteins was observed. In each case, the newly synthesised GFP/YFP-labelled snRNPs accumulated first in coiled bodies and nucleoli, and later in nuclear speckles. Mature snRNPs localised immediately to speckles upon entering the nucleus after cell division. CONCLUSIONS: The complex nuclear localisation of splicing snRNPs results, at least in part, from a specific pathway for newly assembled snRNPs. The data demonstrate that the distribution of snRNPs between coiled bodies and speckles is directed and not random.  (+info)

Interactions of U2 gene loci and their nuclear transcripts with Cajal (coiled) bodies: evidence for PreU2 within Cajal bodies. (2/196)

The Cajal (coiled) body (CB) is a structure enriched in proteins involved in mRNA, rRNA, and snRNA metabolism. CBs have been shown to interact with specific histone and snRNA gene loci. To examine the potential role of CBs in U2 snRNA metabolism, we used a variety of genomic and oligonucleotide probes to visualize in situ newly synthesized U2 snRNA relative to U2 loci and CBs. Results demonstrate that long spacer sequences between U2 coding repeats are transcribed, supporting other recent evidence that U2 transcription proceeds past the 3' box. The presence of bright foci of this U2 locus RNA differed between alleles within the same nucleus; however, this did not correlate with the loci's association with a CB. Experiments with specific oligonucleotide probes revealed signal for preU2 RNA within CBs. PreU2 was also detected in the locus-associated RNA foci, whereas sequences 3' of preU2 were found only in these foci, not in CBs. This suggests that a longer primary transcript is processed before entry into CBs. Although this work shows that direct contact of a U2 locus with a CB is not simply correlated with RNA at that locus, it provides the first evidence of new preU2 transcripts within CBs. We also show that, in contrast to CBs, SMN gems do not associate with U2 gene loci and do not contain preU2. Because other evidence indicates that preU2 is processed in the cytoplasm before assembly into snRNPs, results point to an involvement of CBs in modification or transport of preU2 RNA.  (+info)

Characterization of the nucleolar gene product, treacle, in Treacher Collins syndrome. (3/196)

Treacher Collins syndrome (TCS) is an autosomal dominant disorder of craniofacial development caused by mutations in the gene TCOF1. Its gene product, treacle, consists mainly of a central repeat domain, which shows it to be structurally related to the nucleolar phosphoprotein Nopp140. Treacle remains mostly uncharacterized to date. Herein we show that it, like Nopp140, is a highly phosphorylated nucleolar protein. However, treacle fails to colocalize with Nopp140 to Cajal (coiled) bodies. As in the case of Nopp140, casein kinase 2 appears to be responsible for the unusually high degree of phosphorylation as evidenced by its coimmunoprecipitation with treacle. Based on these and other observations, treacle and Nopp140 exhibit distinct but overlapping functions. The majority of TCOF1 mutations in TCS lead to premature termination codons that could affect the cellular levels of the full-length treacle. We demonstrate however, that the cellular amount of treacle varies less than twofold among a collection of primary fibroblasts and lymphoblasts and regardless of whether the cells were derived from TCS patients or healthy individuals. Therefore, cells of TCS patients possess a mechanism to maintain wild-type levels of full-length treacle from a single allele.  (+info)

Cell cycle-regulated phosphorylation of p220(NPAT) by cyclin E/Cdk2 in Cajal bodies promotes histone gene transcription. (4/196)

Cyclin E/Cdk2 acts at the G1/S-phase transition to promote the E2F transcriptional program and the initiation of DNA synthesis. To explore further how cyclin E/Cdk2 controls S-phase events, we examined the subcellular localization of the cyclin E/Cdk2 interacting protein p220(NPAT) and its regulation by phosphorylation. p220 is localized to discrete nuclear foci. Diploid fibroblasts in Go and G1 contain two p220 foci, whereas S- and G2-phase cells contain primarily four p220 foci. Cells in metaphase and telophase have no detectable focus. p220 foci contain cyclin E and are coincident with Cajal bodies (CBs), subnuclear organelles that associate with histone gene clusters on chromosomes 1 and 6. Interestingly, p220 foci associate with chromosome 6 throughout the cell cycle and with chromosome 1 during S phase. Five cyclin E/Cdk2 phosphorylation sites in p220 were identified. Phospho-specific antibodies against two of these sites react with p220 within CBs in a cell cycle-specific manner. The timing of p220 phosphorylation correlates with the appearance of cyclin E in CBs at the G1/S boundary, and this phosphorylation is maintained until prophase. Expression of p220 activates transcription of the histone H2B promoter. Importantly, mutation of Cdk2 phosphorylation sites to alanine abrogates the ability of p220 to activate the histone H2B promoter. Collectively, these results strongly suggest that p220(NPAT) links cyclical cyclin E/Cdk2 kinase activity to replication-dependent histone gene transcription.  (+info)

Mutational analysis of fibrillarin and its mobility in living human cells. (5/196)

Cajal bodies (CBs) are subnuclear organelles that contain components of a number of distinct pathways in RNA transcription and RNA processing. CBs have been linked to other subnuclear organelles such as nucleoli, but the reason for the presence of nucleolar proteins such as fibrillarin in CBs remains uncertain. Here, we use full-length fibrillarin and truncated fibrillarin mutants fused to green fluorescent protein (GFP) to demonstrate that specific structural domains of fibrillarin are required for correct intranuclear localization of fibrillarin to nucleoli and CBs. The second spacer domain and carboxy terminal alpha-helix domain in particular appear to target fibrillarin, respectively, to the nucleolar transcription centers and CBs. The presence of the RNP domain seems to be a prerequisite for correct targeting of fibrillarin. Time-lapse confocal microscopy of human cells that stably express fibrillarin-GFP shows that CBs fuse and split, albeit at low frequencies. Recovered fluorescence of fibrillarin-GFP in nucleoli and CBs after photobleaching indicates that it is highly mobile in both organelles (estimated diffusion constant approximately 0.02 microm(2) s(-1)), and has a significantly larger mobile fraction in CBs than in nucleoli.  (+info)

Self-association of coilin reveals a common theme in nuclear body localization. (6/196)

We have found that coilin, the marker protein for Cajal bodies (coiled bodies, CBs), is a self-interacting protein, and we have mapped the domain responsible for this activity to the amino-terminus. Together with a nuclear localization signal, the self-interaction domain is necessary and sufficient for localization to CBs. Overexpression of various wild-type and mutant coilin constructs in HeLa cells results in disruption of both CBs and survival motor neurons (SMN) gems. Additionally, we have identified a cryptic nucleolar localization signal (NoLS), within the coilin protein, which may be exposed in specific coilin phospho-isoforms. The implications of these findings are discussed in light of the fact that other proteins known to localize within nuclear bodies (e. g., PML, SMN and Sam68) can also self-associate. Thus protein self-interaction appears to be a general feature of nuclear body marker proteins.  (+info)

In vivo analysis of Cajal body movement, separation, and joining in live human cells. (7/196)

Cajal bodies (also known as coiled bodies) are subnuclear organelles that contain specific nuclear antigens, including splicing small nuclear ribonucleoproteins (snRNPs) and a subset of nucleolar proteins. Cajal bodies are localized in the nucleoplasm and are often found at the nucleolar periphery. We have constructed a stable HeLa cell line, HeLa(GFP-coilin), that expresses the Cajal body marker protein, p80 coilin, fused to the green fluorescent protein (GFP-coilin). The localization pattern and biochemical properties of the GFP-coilin fusion protein are identical to the endogenous p80 coilin. Time-lapse recordings on 63 nuclei of HeLa(GFP-coilin) cells showed that all Cajal bodies move within the nucleoplasm. Movements included translocations through the nucleoplasm, joining of bodies to form larger structures, and separation of smaller bodies from larger Cajal bodies. Also, we observed Cajal bodies moving to and from nucleoli. The data suggest that there may be at least two classes of Cajal bodies that differ in their size, antigen composition, and dynamic behavior. The smaller size class shows more frequent and faster rates of movement, up to 0.9 microm/min. The GFP-coilin protein is dynamically associated with Cajal bodies as shown by changes in their fluorescence intensity over time. This study reveals an unexpectedly high level of movement and interactions of nuclear bodies in human cells and suggests that these movements may be driven, at least in part, by regulated mechanisms.  (+info)

Replication-dependent histone gene expression is related to Cajal body (CB) association but does not require sustained CB contact. (8/196)

Interactions between Cajal bodies (CBs) and replication-dependent histone loci occur more frequently than for other mRNA-encoding genes, but such interactions are not seen with all alleles at a given time. Because CBs contain factors required for transcriptional regulation and 3' end processing of nonpolyadenylated replication-dependent histone transcripts, we investigated whether interaction with CBs is related to metabolism of these transcripts, known to vary during the cell cycle. Our experiments revealed that a locus containing a cell cycle-independent, replacement histone gene that produces polyadenylated transcripts does not preferentially associate with CBs. Furthermore, modest but significant changes in association levels of CBs with replication-dependent histone loci mimic their cell cycle modulations in transcription and 3' end processing rates. By simultaneously visualizing replication-dependent histone genes and their nuclear transcripts for the first time, we surprisingly find that the vast majority of loci producing detectable RNA foci do not contact CBs. These studies suggest some link between CB association and unusual features of replication-dependent histone gene expression. However, sustained CB contact is not a requirement for their expression, consistent with our observations of U7 snRNP distributions. The modest correlation to gene expression instead may reflect transient gene signaling or the nucleation of small CBs at gene loci.  (+info)

Cajal bodies (CBs) are nuclear organelles that occur in a variety of organisms, including vertebrates, insects, and plants. They are most often identified with antibodies against the marker protein coilin. Because the amino acid sequence of coilin is not strongly conserved evolutionarily, coilin orthologues have been difficult to recognize by homology search. Here, we report the identification of Drosophila melanogaster coilin and describe its distribution in tissues of the fly. Surprisingly, we found coilin not only in CBs but also in histone locus bodies (HLBs), calling into question the use of coilin as an exclusive marker for CBs. We analyzed two null mutants in the coilin gene and a piggyBac insertion mutant, which leads to specific loss of coilin from the germline. All three mutants are homozygous viable and fertile. Cells that lack coilin also lack distinct foci of other CB markers, including fibrillarin, the survival motor neuron (SMN) protein, U2 small nuclear RNA (snRNA), U5 snRNA, and the
Human coilin interacting nuclear ATPase protein (hCINAP) directly interacts with coilin, a marker protein of Cajal Bodies (CBs), nuclear organelles involved in the maturation of small nuclear ribonucleoproteins UsnRNPs and snoRNPs. hCINAP has previously been designated as an adenylate kinase (AK6), but is very atypical as it exhibits unusually broad substrate specificity, structural features characteristic of ATPase/GTPase proteins (Walker motifs A and B) and also intrinsic ATPase activity. Despite its intriguing structure, unique properties and cellular localization, the enzymatic mechanism and biological function of hCINAP have remained poorly characterized. Here, we offer the first high-resolution structure of hCINAP in complex with the substrate ADP (and dADP), the structure of hCINAP with a sulfate ion bound at the AMP binding site, and the structure of the ternary complex hCINAP-Mg 2+ADP-Pi. Induced fit docking calculations are used to predict the structure of the hCINAP-Mg 2+ATP-AMP ...

Overwhelming evidence indicates that aspirin and related non-steroidal anti-inflammatory drugs (NSAIDs) have anti-tumour activity and the potential to prevent cancer, particularly colorectal cancer. However, the mechanisms underlying this effect remain hypothetical. Dysregulation of the nuclear factor-kappaB (NF-κB) transcription factor is a common event in many cancer types which contributes to tumour initiation and progression by driving expression of pro-proliferative/anti-apoptotic genes. In this review, we will focus on the current knowledge regarding NSAID effects on the NF-κB signalling pathway in pre-cancerous and cancerous lesions, and the evidence that these effects contribute to the anti-tumour activity of the agents. The nuclear organelle, the nucleolus, is emerging as a central regulator of transcription factor activity and cell growth and death. Nucleolar function is dysregulated in the majority of cancers which promotes cancer growth through direct and indirect mechanisms. Hence, this

N2 - The U1, U2, U4, U5 and U6 small nuclear ribonucleoprotein particles (snRNPs) are essential elements of the spliceosome, the enzyme that catalyzes the excision of introns and the ligation of exons to form a mature mRNA. Since their discovery over a quarter century ago, the structure, assembly and function of spliceosomal snRNPs have been extensively studied. Accordingly, the functions of splicing snRNPs and the role of various nuclear organelles, such as Cajal bodies (CBs), in their nuclear maturation phase have already been excellently reviewed elsewhere.

Confocal microscopy and in situ hybridization procedures have led to enormous progress in the visualization of the spatial organization and dynamics of transcription and RNA‐processing machinery in eukaryotic cells. It is well established that the nucleus is a highly organized structure composed of many different territories, subdomains and organelles (Lamond and Earnshaw, 1998). A state‐of‐the‐art account of the nuclear architecture of plant cells was given by P.Shaw (John Innes Centre, Norwich, UK). Mapping of the RNA polymerase I transcription and rRNA processing sites, using different pre‐rRNA, snoRNA and nucleolar protein probes, indicates that the plant cell nucleolus is organized as a series of concentric layers in which transcription and successive rRNA processing reactions occur. As in vertebrate cells, plant cells contain coiled bodies (CBs), nuclear organelles of still poorly defined function. Since CB components include several small RNAs, and also proteins related to ...
Individuals with intellectual disability (ID) often engage in behaviours that are labelled as challenging (challenging behaviours; CB). CBs are actions that may place the individual at risk of harm or exclusion, or may place other people (e.g. carers) at risk of harm [1]. Thus, CBs are defined socially, in terms of their impact. Behaviours labelled as challenging typically include actions such as anger and aggression, self-injurious behaviours (e.g. self-biting, hitting body parts against objects, scratching and gouging), destruction of property, and inappropriate or risky social behaviour. CBs are, by definition, a significant challenge for services and impact negatively on the quality of life of people with ID. CBs are also related to risk of abusive practices (cf. Winterbourne View scandal exposed by BBC Panorama), increased carer stress [2, 3], and high cost of support services [4]. High quality epidemiological research suggests that 18-19% of adults with ID known to services engage in CB ...
This work combines (i) an siRNA‐based biochemical analysis of RNA and protein constituents of the tri‐snRNP in vivo with (ii) the use of fluorescence microscopy to locate these constituents in the nucleus. Our initial finding is that when the cells are depleted of hPrp31 or hPrp6 protein by RNAi knockdown, the formation of U4/U6.U5 tri‐snRNP is inhibited, and stable U4/U6 di‐snRNPs and U5 snRNPs accumulate in the cell (Figure 2). This demonstrates for the first time in vivo that the U4/U6 protein hPrp31 is essential for the interaction of the U4/U6 di‐snRNP with the 20S U5 snRNP, and is consistent with previous studies performed in vitro (Makarova et al, 2002). A similar property must also now be ascribed to the U5 protein hPrp6 which, like the hPrp31 protein, is essential for the stability of the tri‐snRNP in vivo. It is known from two‐hybrid analyses that hPrp31 and hPrp6 bind strongly and specifically to one another (Makarova et al, 2002), and we therefore consider it likely ...

When they studied cells derived from the mutant mice, they found what they term residual CBs. These foci contain some of the typical proteins found in CBs, but they fail to stain brightly when treated with silver, and lack two complexes that are normally prominent components of CBs: snRNPs and the SMN (survival motor neuron) protein complex. The authors conclude that coilin is necessary for recruiting these factors to CBs. Indeed, when they transiently expressed wild-type coilin in the mutant cells, bodies formed that contain both the previously missing factors. ▪. ...

When thio-T was added to GVs isolated from stage V or VI oocytes staining was essentially instantaneous (Movie 1). Both the pattern and number of amyloid-positive particles detected replicated the results seen with sectioned ovary (Fig. 2B, Fig. 1).

Over time, the approach to cerebral palsy management has shifted away from narrow attempts to fix individual physical problems - such as spasticity in a particular limb - to making such treatments part of a larger goal of maximizing the persons independence and community engagement. Much of childhood therapy is aimed at improving gait and walking. Approximately 60% of people with CP are able to walk independently or with aids at adulthood. However, the evidence base for the effectiveness of intervention programs reflecting the philosophy of independence has not yet caught up: effective interventions for body structures and functions have a strong evidence base, but evidence is lacking for effective interventions targeted toward participation, environment, or personal factors. There is also no good evidence to show that an intervention that is effective at the body-specific level will result in an improvement at the activity level, or vice versa. Although such cross-over benefit might happen, ...

Phase transitions are found everywhere in nature, and I am interested in understanding how living cells harness them to generate chemically distinct subcellular environments. Whereas 2D phase transitions are thought to organise the membranes that encapsulate organelles such as lysosomes, endosomes, and the endoplasmic reticulum, 3D liquid-liquid phase transitions produce membraneless organelles such as nucleoli, Cajal bodies, P-granules and nuage. These membraneless organelles behave as tiny liquid droplets suspended inside the cell, and can rapidly condense and dissolve with changes in the cell-cycle, or in response to stresses such as viral infection. I am particularly interested in uncovering the molecular details of how membraneless organelles are formed in cells, and in how the unique solvent environment of their interior influences biochemical reactions.. ...
