    Topics: Biology
    Notes: Abstract A low-temperature-responsive gene, blt 801, isolated from a winter barley (Hordeum vulgare L.) cDNA library prepared from leaf meristematic tissue, was sequenced. The deduced amino acid sequence predicts a glycine-rich RNA-binding protein (GR-RNP) which was homology to stress-responsive GR-RNPs from several other plant species. BLT 801 is a two-domain protein, the amino-terminal domain comprises a consensus RNA-binding domain similar to that found in many eukaryotic genes and the carboxy-terminal domain is extremely glycine-rich (68.5% glycine). Blt 801 mRNA also accumulates in response to the phytohormone abscisic acid. The protein encoded by blt 801 has been produced as a recombinant fusion protein using a bacterial expression vector. The fusion protein, a chimaera of glutathione S-transferase and BLT 801, has been used in studies to determine nucleic acid binding and other characteristics. Binding studies with single-stranded nucleic acids show that BLT 801 has affinity for homoribopolymers G, A and U but not C, it also binds to single-stranded DNA and selects RNA molecules containing open loop structures enriched in adenine but low in cytosine. BLT 801 has a consensus motif for phosphorylation by cAMP protein kinase (PKA) at the junction between the two domains which can be phosphorylated by PKA in vitro and which, by analogy to animal studies, may have significance for controlling enzyme function.

    Topics: Biology
    Notes: Abstract Transcription and translation inhibitors have been used to investigate the role of mRNA stability in the low-temperature-regulated expression of the post-transcriptionally controlled low temperature responsive barley gene family, blt14. Genomic clones (blt14.1, blt14.2) representing additional members of the blt14 gene family have been isolated and sequenced. Gene specific probes have been used to analyse the spatial expression of each individual member of the blt14 gene family. Findings indicate that all of the genes are responsive to low temperature, but the organ distribution is different for each gene. The results indicate that blt14.0 mRNA is stabilised by a low-temperature-dependent protein factor. Taken together, the results suggest that organ-specific post-transcriptional mechanisms are important in the low-temperature regulation of blt14 gene expression.

    Topics: Biology
    Notes: Abstract Callus cultures were initiated from apical meristem explants of one to four-week-old aseptically-grown barley (Hordeum vulgare L. cv. Atlas 57) plants. Embryogenic callus and plants were produced in three separate experiments; the cultures have retained regenerative capacity for three years after initiation. Our results demonstrate that explants other than immature embryos are embryogenically competent in barley and that regeneration occurs by both somatic embryogenesis and organogenesis.

    Identification of promoter elements in a low-temperature-responsive gene (blt4.9) from barley (Hordeum vulgare L.) (1998)

    Keywords: barley ; cold ; electrophoretic mobility shift assay ; lipid transfer protein ; low temperature ; promoter
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The blt4 barley gene family encodes non-specific lipid transfer proteins and has been shown, by in situ localisation, to be expressed in the epidermal cells of leaves. The transcriptionally controlled, low-temperature-responsive member of this gene family, blt4.9, is predominantly expressed in shoot meristems. The promoter region (1938 bp) of blt4.9 contains sequence motifs which have been implicated in responses to low temperature, abscisic acid and other environmental factors. Deletion analysis showed that a 42 bp sequence proximal to, but not including, the CAAT and TATA boxes, confers enhanced low-temperature response to a reporter gene in a barley shoot explant transient expression system. Other promoter regions were shown to contain negative and positive regulatory regions. Electrophoretic mobility shift analysis (EMSA) was used with nuclear proteins from either low-temperature- or control-temperature-treated plants to further investigate the blt4.9 promoter. Synthetic oligonucleotides were used to identify a hexanucleotide, CCGAAA, within the 42 bp, low-temperature-responsive promoter region, as the binding site of a low-mobility nuclear protein complex. This complex was present in nuclear extracts from both low-temperature-treated and control plants and was the only complex formed within this region. Mutation of the CCGAAA motif within the low-temperature-responsive 42 bp promoter sequence reduced low-temperature responsiveness to basal levels. A related upstream element, CCGAC, known to be a low-temperature-responsive element in other plants, did not bind to nuclear proteins in this study. It is proposed that the hexanucleotide CCGAAA, at -195 from the first ATG, is involved in the low-temperature response of blt4.9 in barley.

    Persistent site-specific remodeling of a nucleosome array by transient action of the SWI/SNF complex (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-07-26
    Description: The SWI/SNF complex participates in the restructuring of chromatin for transcription. The function of the yeast SWI/SNF complex in the remodeling of a nucleosome array has now been analyzed in vitro. Binding of the purified SWI/SNF complex to a nucleosome array disrupted multiple nucleosomes in an adenosine triphosphate-dependent reaction. However, removal of SWI/SNF left a deoxyribonuclease I-hypersensitive site specifically at a nucleosome that was bound by derivatives of the transcription factor Gal4p. Analysis of individual nucleosomes revealed that the SWI/SNF complex catalyzed eviction of histones from the Gal4-bound nucleosomes. Thus, the transient action of the SWI/SNF complex facilitated irreversible disruption of transcription factor-bound nucleosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Owen-Hughes, T -- Utley, R T -- Cote, J -- Peterson, C L -- Workman, J L -- GM47867/GM/NIGMS NIH HHS/ -- R01 GM049650/GM/NIGMS NIH HHS/ -- R37 GM049650/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1996 Jul 26;273(5274):513-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology and Center for Gene Regulation, Pennsylvania State University, University Park, PA 16802-4500, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8662543" target="_blank"〉PubMed〈/a〉

    The neuron-specific protein PGP 9.5 is a ubiquitin carboxyl-terminal hydrolase (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-11-03
    Description: A complementary DNA (cDNA) for ubiquitin carboxyl-terminal hydrolase isozyme L3 was cloned from human B cells. The cDNA encodes a protein of 230 amino acids with a molecular mass of 26.182 daltons. The human protein is very similar to the bovine homolog, with only three amino acids differing in over 100 residues compared. The amino acid sequence deduced from the cDNA was 54% identical to that of the neuron-specific protein PGP 9.5. Purification of bovine PGP 9.5 confirmed that it is also a ubiquitin carboxyl-terminal hydrolase. These results suggest that a family of such related proteins exists and that their expression is tissue-specific.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilkinson, K D -- Lee, K M -- Deshpande, S -- Duerksen-Hughes, P -- Boss, J M -- Pohl, J -- New York, N.Y. -- Science. 1989 Nov 3;246(4930):670-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, Emory University School of Medicine, Atlanta, GA 30322.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2530630" target="_blank"〉PubMed〈/a〉

    Cdc13p: a single-strand telomeric DNA-binding protein with a dual role in yeast telomere maintenance (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-10-11
    Description: The CDC13 gene has previously been implicated in the maintenance of telomere integrity in Saccharomyces cerevisiae. With the use of two classes of mutations, here it is shown that CDC13 has two discrete roles at the telomere. The cdc13-2est mutation perturbs a function required in vivo for telomerase regulation but not in vitro for enzyme activity, whereas cdc13-1ts defines a separate essential role at the telomere. In vitro, purified Cdc13p binds to single-strand yeast telomeric DNA. Therefore, Cdc13p is a telomere-binding protein required to protect the telomere and mediate access of telomerase to the chromosomal terminus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nugent, C I -- Hughes, T R -- Lue, N F -- Lundblad, V -- New York, N.Y. -- Science. 1996 Oct 11;274(5285):249-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Human Genetics and Cell and Molecular Biology Program, Baylor College of Medicine, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8824190" target="_blank"〉PubMed〈/a〉

    GTBP, a 160-kilodalton protein essential for mismatch-binding activity in human cells (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-06-30
    Description: DNA mismatch recognition and binding in human cells has been thought to be mediated by the hMSH2 protein. Here it is shown that the mismatch-binding factor consists of two distinct proteins, the 100-kilodalton hMSH2 and a 160-kilodalton polypeptide, GTBP (for G/T binding protein). Sequence analysis identified GTBP as a new member of the MutS homolog family. Both proteins are required for mismatch-specific binding, a result consistent with the finding that tumor-derived cell lines devoid of either protein are also devoid of mismatch-binding activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Palombo, F -- Gallinari, P -- Iaccarino, I -- Lettieri, T -- Hughes, M -- D'Arrigo, A -- Truong, O -- Hsuan, J J -- Jiricny, J -- New York, N.Y. -- Science. 1995 Jun 30;268(5219):1912-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Istituto di Ricerche di Biologia Molecolare P.
