One of the two major pharmacological subdivisions of adrenergic receptors that were originally defined by the relative potencies of various adrenergic compounds. The alpha receptors were initially described as excitatory receptors that post-junctionally stimulate SMOOTH MUSCLE contraction. However, further analysis has revealed a more complex picture involving several alpha receptor subtypes and their involvement in feedback regulation.

Cell surface receptor for LAMININ, epiligrin, FIBRONECTINS, entactin, and COLLAGEN. Integrin alpha3beta1 is the major integrin present in EPITHELIAL CELLS, where it plays a role in the assembly of BASEMENT MEMBRANE as well as in cell migration, and may regulate the functions of other integrins. Two alternatively spliced isoforms of the alpha subunit (INTEGRIN ALPHA3), are differentially expressed in different cell types.
An integrin alpha subunit that is unique in that it does not contain an I domain, and its proteolytic cleavage site is near the middle of the extracellular portion of the polypeptide rather than close to the membrane as in other integrin alpha subunits.
An integrin alpha subunit that primarily associates with INTEGRIN BETA1 or INTEGRIN BETA4 to form laminin-binding heterodimers. Integrin alpha6 has two alternatively spliced isoforms: integrin alpha6A and integrin alpha6B, which differ in their cytoplasmic domains and are regulated in a tissue-specific and developmental stage-specific manner.
An integrin found in FIBROBLASTS; PLATELETS; MONOCYTES, and LYMPHOCYTES. Integrin alpha5beta1 is the classical receptor for FIBRONECTIN, but it also functions as a receptor for LAMININ and several other EXTRACELLULAR MATRIX PROTEINS.
Integrin alpha4beta1 is a FIBRONECTIN and VCAM-1 receptor present on LYMPHOCYTES; MONOCYTES; EOSINOPHILS; NK CELLS and thymocytes. It is involved in both cell-cell and cell- EXTRACELLULAR MATRIX adhesion and plays a role in INFLAMMATION, hematopoietic cell homing and immune function, and has been implicated in skeletal MYOGENESIS; NEURAL CREST migration and proliferation, lymphocyte maturation and morphogenesis of the PLACENTA and HEART.
An interleukin-1 subtype that occurs as a membrane-bound pro-protein form that is cleaved by proteases to form a secreted mature form. Unlike INTERLEUKIN-1BETA both membrane-bound and secreted forms of interleukin-1alpha are biologically active.
An integrin found on fibroblasts, platelets, endothelial and epithelial cells, and lymphocytes where it functions as a receptor for COLLAGEN and LAMININ. Although originally referred to as the collagen receptor, it is one of several receptors for collagen. Ligand binding to integrin alpha2beta1 triggers a cascade of intracellular signaling, including activation of p38 MAP kinase.
A subclass of alpha-adrenergic receptors that mediate contraction of SMOOTH MUSCLE in a variety of tissues such as ARTERIOLES; VEINS; and the UTERUS. They are usually found on postsynaptic membranes and signal through GQ-G11 G-PROTEINS.
This integrin alpha subunit combines with INTEGRIN BETA1 to form a receptor (INTEGRIN ALPHA5BETA1) that binds FIBRONECTIN and LAMININ. It undergoes posttranslational cleavage into a heavy and a light chain that are connected by disulfide bonds.
Integrin alpha1beta1 functions as a receptor for LAMININ and COLLAGEN. It is widely expressed during development, but in the adult is the predominant laminin receptor (RECEPTORS, LAMININ) in mature SMOOTH MUSCLE CELLS, where it is important for maintenance of the differentiated phenotype of these cells. Integrin alpha1beta1 is also found in LYMPHOCYTES and microvascular endothelial cells, and may play a role in angiogenesis. In SCHWANN CELLS and neural crest cells, it is involved in cell migration. Integrin alpha1beta1 is also known as VLA-1 and CD49a-CD29.
A subclass of alpha-adrenergic receptors found on both presynaptic and postsynaptic membranes where they signal through Gi-Go G-PROTEINS. While postsynaptic alpha-2 receptors play a traditional role in mediating the effects of ADRENERGIC AGONISTS, the subset of alpha-2 receptors found on presynaptic membranes signal the feedback inhibition of NEUROTRANSMITTER release.
A cell surface receptor mediating cell adhesion to the EXTRACELLULAR MATRIX and to other cells via binding to LAMININ. It is involved in cell migration, embryonic development, leukocyte activation and tumor cell invasiveness. Integrin alpha6beta1 is the major laminin receptor on PLATELETS; LEUKOCYTES; and many EPITHELIAL CELLS, and ligand binding may activate a number of signal transduction pathways. Alternative splicing of the cytoplasmic domain of the alpha6 subunit (INTEGRIN ALPHA6) results in the formation of A and B isoforms of the heterodimer, which are expressed in a tissue-specific manner.
The sequence of PURINES and PYRIMIDINES in nucleic acids and polynucleotides. It is also called nucleotide sequence.
This intrgrin is a key component of HEMIDESMOSOMES and is required for their formation and maintenance in epithelial cells. Integrin alpha6beta4 is also found on thymocytes, fibroblasts, and Schwann cells, where it functions as a laminin receptor (RECEPTORS, LAMININ) and is involved in wound healing, cell migration, and tumor invasiveness.
The alpha subunits of integrin heterodimers (INTEGRINS), which mediate ligand specificity. There are approximately 18 different alpha chains, exhibiting great sequence diversity; several chains are also spliced into alternative isoforms. They possess a long extracellular portion (1200 amino acids) containing a MIDAS (metal ion-dependent adhesion site) motif, and seven 60-amino acid tandem repeats, the last 4 of which form EF HAND MOTIFS. The intracellular portion is short with the exception of INTEGRIN ALPHA4.
A family of transmembrane glycoproteins (MEMBRANE GLYCOPROTEINS) consisting of noncovalent heterodimers. They interact with a wide variety of ligands including EXTRACELLULAR MATRIX PROTEINS; COMPLEMENT, and other cells, while their intracellular domains interact with the CYTOSKELETON. The integrins consist of at least three identified families: the cytoadhesin receptors(RECEPTORS, CYTOADHESIN), the leukocyte adhesion receptors (RECEPTORS, LEUKOCYTE ADHESION), and the VERY LATE ANTIGEN RECEPTORS. Each family contains a common beta-subunit (INTEGRIN BETA CHAINS) combined with one or more distinct alpha-subunits (INTEGRIN ALPHA CHAINS). These receptors participate in cell-matrix and cell-cell adhesion in many physiologically important processes, including embryological development; HEMOSTASIS; THROMBOSIS; WOUND HEALING; immune and nonimmune defense mechanisms; and oncogenic transformation.

A tunable ratchet driving human RNA polymerase II translocation adjusted by accurately templated nucleoside triphosphates loaded at downstream sites and by elongation factors. (1/38)

When nucleoside triphosphate (NTP) substrates and alpha-amanitin are added to a human RNA polymerase II elongation complex simultaneously, the reaction becomes stalled in the core of the bond synthesis mechanism. The mode of stalling is influenced by NTP substrates at the active site and at downstream sites and by transcription factor IIF (TFIIF) and TFIIS. NTP substrates templated at i+2, i+3, and i+4 downstream DNA sites can reverse the previously stable binding of an NTP loaded at the i+1 substrate site. Deoxy-(d)NTPs and NDPs (nucleoside diphosphates) do not substitute for NTPs at the i+2 and i+3 positions (considered together) or the i+4, i+5, and i+6 positions (considered together). The mode of stalling is altered by changing the number of downstream template sites that are accurately occupied by NTPs and by changing NTP concentration. In the presence of the translocation blocker alpha-amanitin, a steady state condition is established in which RNA polymerase II stably loads an NTP substrate at i+1 and forms a phosphodiester bond but cannot rapidly complete bond synthesis by releasing pyrophosphate. These observations support a role for incoming NTP substrates in stimulating translocation; results appear inconsistent with the secondary pore being the sole route of NTP entry for human RNA polymerase II, and results indicate mechanisms of dynamic error avoidance and error correction during rapid RNA synthesis.  (+info)

Nucleolar translocalization of GRA10 of Toxoplasma gondii transfectionally expressed in HeLa cells. (2/38)

Toxoplasma gondii GRA10 expressed as a GFP-GRA10 fusion protein in HeLa cells moved to the nucleoli within the nucleus rapidly and entirely. GRA10 was concentrated specifically in the dense fibrillar component of the nucleolus morphologically by the overlap of GFP-GRA10 transfection image with IFA images by monoclonal antibodies against GRA10 (Tg378), B23 (nucleophosmin) and C23 (nucleolin). The nucleolar translocalization of GRA10 was caused by a putative nucleolar localizing sequence (NoLS) of GRA10. Interaction of GRA10 with TATA-binding protein associated factor 1B (TAF1B) in the yeast two-hybrid technique was confirmed by GST pull-down assay and immunoprecipitation assay. GRA10 and TAF1B were also co-localized in the nucleolus after co-transfection. The nucleolar condensation of GRA10 was affected by actinomycin D. Expressed GFP-GRA10 was evenly distributed over the nucleoplasm and the nucleolar locations remained as hollows in the nucleoplasm under a low dose of actinomycin D. Nucleolar localizing and interacting of GRA10 with TAF1B suggested the participation of GRA10 in rRNA synthesis of host cells to favor the parasitism of T. gondii.  (+info)

RNA is an integral component of chromatin that contributes to its structural organization. (3/38)

Chromatin structure is influenced by multiples factors, such as pH, temperature, nature and concentration of counterions, post-translational modifications of histones and binding of structural non-histone proteins. RNA is also known to contribute to the regulation of chromatin structure as chromatin-induced gene silencing was shown to depend on the RNAi machinery in S. pombe, plants and Drosophila. Moreover, both in Drosophila and mammals, dosage compensation requires the contribution of specific non-coding RNAs. However, whether RNA itself plays a direct structural role in chromatin is not known. Here, we report results that indicate a general structural role for RNA in eukaryotic chromatin. RNA is found associated to purified chromatin prepared from chicken liver, or cultured Drosophila S2 cells, and treatment with RNase A alters the structural properties of chromatin. Our results indicate that chromatin-associated RNAs, which account for 2%-5% of total chromatin-associated nucleic acids, are polyA(-) and show a size similar to that of the DNA contained in the corresponding chromatin fragments. Chromatin-associated RNA(s) are not likely to correspond to nascent transcripts as they are also found bound to chromatin when cells are treated with alpha-amanitin. After treatment with RNase A, chromatin fragments of molecular weight >3.000 bp of DNA showed reduced sedimentation through sucrose gradients and increased sensitivity to micrococcal nuclease digestion. This structural transition, which is observed both at euchromatic and heterochromatic regions, proceeds without loss of histone H1 or any significant change in core-histone composition and integrity.  (+info)

Extragenic accumulation of RNA polymerase II enhances transcription by RNA polymerase III. (4/38)

Recent genomic data indicate that RNA polymerase II (Pol II) function extends beyond conventional transcription of primarily protein-coding genes. Among the five snRNAs required for pre-mRNA splicing, only the U6 snRNA is synthesized by RNA polymerase III (Pol III). Here we address the question of how Pol II coordinates the expression of spliceosome components, including U6. We used chromatin immunoprecipitation (ChIP) and high-resolution mapping by PCR to localize both Pol II and Pol III to snRNA gene regions. We report the surprising finding that Pol II is highly concentrated approximately 300 bp upstream of all five active human U6 genes in vivo. The U6 snRNA, an essential component of the spliceosome, is synthesized by Pol III, whereas all other spliceosomal snRNAs are Pol II transcripts. Accordingly, U6 transcripts were terminated in a Pol III-specific manner, and Pol III localized to the transcribed gene regions. However, synthesis of both U6 and U2 snRNAs was alpha-amanitin-sensitive, indicating a requirement for Pol II activity in the expression of both snRNAs. Moreover, both Pol II and histone tail acetylation marks were lost from U6 promoters upon alpha-amanitin treatment. The results indicate that Pol II is concentrated at specific genomic regions from which it can regulate Pol III activity by a general mechanism. Consequently, Pol II coordinates expression of all RNA and protein components of the spliceosome.  (+info)

You may have fried the triggers--most of these cheap eBay type triggers have a voltage limit of around 300V, and the Vivitar 283s are known to go higher. So, maybe a voltmeter would be worth the investment. I would also go to the standby advice of check the batteries and the channel settings.. Theoretically, those triggers (which look like theyre for Nikon from the pass-through shoes contact pattern) should work. But if they rely upon a TTL pin signal of some kind, that could be another issue. Its unlikely that this is the case, since those triggers have separate Tx/Rx units, and Ive only see this type of misfunction with the Yongnuo RF-603s (which used a TTL signal to auto switch between Tx/Rx modes, so with non-Canon/Nikon hotshoes, the transmitter unit never went into Tx mode--which is why Yongnuo made an RF-603 II).. Ive seen reports that the Yongnuo RF-603ii triggers work on NEX (and Fuji X and micro four-thirds), but the sync voltage limit is still only 300V (still better than the 11V ...
If you have a question about this talk, please contact Florian Markowetz.. We are developing computational models of transcription and its regulation from high-throughput time course data. I will discuss two models: (1) We model RNA polymerase (pol-II) dynamics using data from pol-II ChIP-Seq time course datasets (wa Maina et al. 2014). Our model is used to estimate the elongation speed and promoter activation kinetics for early targets of ER-alpha in MCF7 cells. By clustering the promoter activation profiles we can associate differences in the kinetics with transcription factor binding, e.g. the earliest clusters are all associated with nearby FOXA1 binding. (2) We model the relationship between pol-II dynamics and mRNA production by combining 3 pol-II ChIP-Seq data with RNA -Seq data. We find that 11% of genes where we can fit our model exhibit surprisingly long production delays which appear to be associated with splicing. Although transcription delays are longer than splicing delays for ...

Spatial/temporal control of Cas9 guide RNA expression could considerably expand the utility of CRISPR-based technologies. Current approaches based on tRNA processing offer a promising strategy but suffer from high background. Here, to address this limitation, we present a screening platform which allows simultaneous measurements of the promoter strength, 5, and 3 processing efficiencies across a library of tRNA variants. This analysis reveals that the sequence determinants underlying these activities, while overlapping, are dissociable. Rational design based on the ensuing principles allowed us to engineer an improved tRNA scaffold that enables highly specific guide RNA production from a Pol-II promoter. When benchmarked against other reported systems this tRNA scaffold is superior to most alternatives, and is equivalent in function to an optimized version of the Csy4-based guide RNA release system. The results and methods described in this manuscript enable avenues of research both in genome
Galerina marginata is a species of poisonous fungus in the family Hymenogastraceae of the order Agaricales. Prior to 2001, the species G. autumnalis, G. oregonensis, G. unicolor, and G. venenata were thought to be separate due to differences in habitat and the viscidity of their caps, but phylogenetic analysis showed that they are all the same species. The fruit bodies of this fungus have brown to yellow-brown caps that fade in color when drying. The gills are brownish and give a rusty spore print. A well-defined membranous ring is typically seen on the stems of young specimens but often disappears with age. In older fruit bodies, the caps are flatter and the gills and stems browner. The species is a classic little brown mushroom-a catchall category that includes all small to medium-sized, hard-to-identify brownish mushrooms, and may be easily confused with several edible species. Galerina marginata is widespread in the Northern Hemisphere, including Europe, North America, and Asia, and has ...
Chelatable, mobile forms of divalent zinc, Zn(II), play essential signaling roles in mammalian biology. A complex network of zinc import and transport proteins has evolved to control zinc concentration and distribution on a subcellular level. Understanding the action of mobile zinc requires tools that can detect changes in Zn(II) concentrations at discrete cellular locales. We present here a zinc-responsive, reaction-based, targetable probe based on the diacetyled form of Zinpyr-1. The compound, (6-amidoethyl)triphenylphosphonium Zinpyr-1 diacetate (DA-ZP1-TPP), is essentially nonfluorescent in the metal-free state; however, exposure to Zn(II) triggers metal-mediated hydrolysis of the acetyl groups to afford a large, rapid, and zinc-induced fluorescence response. DA-ZP1-TPP is insensitive to intracellular esterases over a 2-h period and is impervious to proton-induced turn-on. A TPP unit is appended for targeting mitochondria, as demonstrated by live cell fluorescence imaging studies. The ...

The actin genes of Trypanosoma brucei are transcribed constitutively during the parasite life-cycle, by a polymerase sensitive to alpha-amanitin (1). The start region of the actin gene transcription unit was mapped by virtue of the accumulation of promoter-proximal transcripts which occurs following moderate UV irradiation (2 - 6). This region, located about 4 kilobases upstream from the genes, was able to direct transient expression of the bacterial Chloramphenicol Acetyl Transferase (CAT) gene in both bloodstream and procyclic forms of the parasite. The essential region of the promoter was defined by deletion, and appeared to be within 600 bp upstream from the putative transcription start site. It does not share significant homology with the other trypanosome promoters described so far (VSG, procyclin, rDNA), which all direct alpha-amanitin resistant transcription. ...

Giardia lamblia is an early branching eukaryote, and although distinctly eukaryotic in its cell and molecular biology, transcription and translation in G. lamblia demonstrate important differences from these processes in higher eukaryotes. The cyclic octapeptide amanitin is a relatively selective inhibitor of eukaryotic RNA polymerase II (RNAP II) and is commonly used to study RNAP II transcription. Therefore, we measured the sensitivity of G. lamblia RNAP II transcription to alpha-amanitin and found that unlike most other eukaryotes, RNAP II transcription in Giardia is resistant to 1 mg/ml amanitin. In contrast, 50 microg/ml amanitin inhibits 85% of RNAP III transcription activity using leucyl-tRNA as a template. To better understand transcription in G. lamblia, we identified 10 of the 12 known eukaryotic rpb subunits, including all 10 subunits that are required for viability in Saccharomyces cerevisiae. The amanitin motif (amanitin binding site) of Rpb1 from G. lamblia has amino acid ...

The marginated tortoise was formally described by German naturalist Johann David Schoepff in 1789; its specific epithet marginata is a straightforward derivation from the Latin term for marginated. The nominate subspecies is the Greek marginated tortoise, Testudo marginata marginata. Three additional subspecies of marginated tortoises have been named: The Sardinian marginated tortoise (T. m. sarda) is the name usually used to separate the population on the island of Sardinia. These tortoises have less strongly bent tiles in the posterior of their carapaces, and the posterior of the carapace is almost smooth compared with the saw-like T. m. marginata. Clearly distinct according to morphology and entirely allopatric, it cannot be distinguished by mtDNA cytochrome b and nDNA ISSR sequence analysis.[3] Lineage sorting has not occurred to a considerable degree; consequently, the more geographically isolated Sardinian population is presumably of quite recent origin. Indeed, it appears to derive from ...
