  1. 1. Connecting Systemic RNAi to the Endomembrane System in Caenorhabditis elegans

    Författare :Benjamin T. Holmgren; Andrea Hinas; Gerhart Wagner; Peter Brodersen; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Systemic RNAi; RNAi inheritance; Endomembrane system; Late endosome; SID-5; SEC-22; SYX-6; C12D8.1; RNA; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Sammanfattning : RNA interference (RNAi) is a gene regulation mechanism conserved among eukaryotes. To silence gene expression, RNAi relies on a short single-stranded guide RNA to steer the RNA-induced Silencing Complex (RISC) to mRNAs with guide strand-complementary sequences. RNAi is a highly membrane-associated process. LÄS MER

  2. 2. Targeting and function of CAH1 : Characterization of a novel protein pathway to the plant cell chloroplast

    Författare :Stefan Burén; Göran Samuelsson; Muriel Bardor; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; chloroplast; endomembrane system; CAH1; protein targeting; N-glycosylation; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The chloroplast is the organelle within a plant cell where photosynthesis takes place. This organelle originates from a cyanobacterium that was engulfed by a eukaryotic cell. LÄS MER

  3. 3. Systemic RNAi Relies on the Endomembrane System in Caenorhabditis elegans

    Författare :Yani Zhao; Andrea Hinas; Staffan Svärd; Simon Tuck; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Systemic RNAi; RNAi inheritance; late endosomes MVBs; SID-5; SEC-22; SYX-6; C12D8.1; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : The membrane system of a eukaryotic cell is a large and complex system handling the transport, exchange and degradation of many kinds of material. Recent research shows that double-stranded RNA (dsRNA) mediated gene silencing (RNA interference) is a membrane related process. LÄS MER

  4. 4. The functional organization of nuclear membrane proteins and development of new technology for studies of cell signaling

    Författare :Ricardo A. Figueroa; Einar Hallberg; Yosef Gruenbaum; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : The eukaryotic cell is defined by the nucleus, which is delimited by a double membrane structure termed the nuclear envelope (NE). The NE is implicated in a multitude of different processes, for example chromatin organization. LÄS MER

  5. 5. Membrane-remodeling by SNX18 in endosomal transport and autophagy

    Författare :Karin Håberg; Sven Carlsson; Geir Bjørkøy; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sorting nexin; SNX9-family; SNX18; endosomal transport; autophagy; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : The intracellular space of eukaryotic cells is subdivided into functionally distinct membrane-enclosed organelles. Regulation of these intracellular membranes requires an intricate network of specialized lipids and proteins that maintain organellar integrity and mediate transport between organelles. LÄS MER
