• EI24 tethers endoplasmic reticulum and mitochondria to regulate autophagy flux. (nih.gov)
  • Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology covers all aspects of ER morphology and function, as well as its interactions with the nucleus, Golgi, and mitochondria. (cshlpress.com)
  • Although it is still not clear where autophagosome membranes originate, possible sources are the endoplasmic reticulum (ER), mitochondria, and the Golgi [ 3 ]. (hindawi.com)
  • This orientation is maintained during membrane trafficking - proteins, lipids, glycoconjugates facing the lumen of the ER and Golgi get expressed on the extracellular side of the plasma membrane. (wikipedia.org)
  • In eucaryotic cells, new phospholipids are manufactured by enzymes bound to the part of the endoplasmic reticulum membrane that faces the cytosol. (wikipedia.org)
  • I am a plant cell biologist and protein biochemist at Oxford Brookes University with expertise in the structure and function of the plant endoplasmic reticulum (ER), membrane proteins and auxin biosynthesis using biochemical techniques as well as high-resolution live cell imaging.

  • This large reticulum comprises stacks of flattened membrane bound compartments called cisternae which are laterally linked to form the so-called Golgi ribbon. (frontiersin.org)
  • They manifest as fragmentation-transformation of the Golgi ribbon into disconnected stacks, cisternae, tubules and vesicles, and as atrophy-loss of Golgi membrane material. (frontiersin.org)
  • Contributors examine how proteins translocate across the ER membrane, the processes that occur inside the ER lumen (e.g., folding, glycosylation, and disulfide bond formation), and how the proteins are packaged into vesicles and transported to the Golgi. (cshlpress.com)
  • Any process that modulates the frequency, rate or extent of retrograde vesicle-mediated transport, Golgi to ER. (mcw.edu)
  • Secretory proteins exit the endoplasmic reticulum (ER) in coat protein complex II (COPII)-coated vesicles and then progress through the Golgi complex before delivery to their final destination. (biologists.com)
  • The directed movement of substances from the Golgi back to the endoplasmic reticulum, mediated by vesicles bearing specific protein coats such as COPI or COG. (ntu.edu.sg)
  • The endoplasmic reticulum translates proteins and transports items throughout the cell. (protopage.com)
  • Endoplasmic reticulum stress (ERS) might be stimulated by a dysfunctional activity of ER dealing with the misfolded or unfold proteins [ 1 ]. (hindawi.com)
  • These important questions got a new boost by the discovery of mutations in genes encoding Golgi-related proteins as direct causes of neurodegeneration. (frontiersin.org)
  • Most glycosylated proteins are glycosylated in the rough endoplasmic reticulum (ER) or Golgi by glycosyltransferases. (nih.gov)
  • However, both endoplasmic reticulum and Golgi morphology became distorted, with the Golgi cisternae becoming significantly dilated, particularly at the trans-face. (ox.ac.uk)
  • Functions as a sorting receptor in the Golgi compartment and as a clearance receptor on the cell surface. (abcam.com)
  • Taken together, these experiments revealed that Vapyrin-bodies have an endosomal identity with trans-Golgi features, and that VAPYRIN interacts with a symbiotic R-SNARE of the VAMP721 family, that localizes to the same compartment. (frontiersin.org)
  • These data argue that the total flux of secretory cargo impacts upon the biogenesis and maintenance of secretory structures and organelles in T. brucei, including the ERES and Golgi. (ox.ac.uk)
  • The issue starts with a summary on Golgi functional organization in neurons (Valenzuela and Perez) and the relation of this organelle with microtubules (Sanders and Kaverina) . (frontiersin.org)
  • Golgi/secretory granule/endoplasmic reticulum Zn 2+ uptake (into Golgi, the ER, or granules) permease, ZnT6. (tcdb.org)
  • Similarly, the number of endoplasmic reticulum exit sites (ERES) in post-mitotic cells dropped from 3.9 ± 0.6 to 2.7 ± 0.1 eight hours after blocking VSG synthesis. (ox.ac.uk)
  • The number of Golgi decreased, particularly in post-mitotic cells, from 3.5 ± 0.6 to 2.0 ± 0.04 per cell. (ox.ac.uk)
  • C) High magnification of Cache Valley virus particles within a Golgi vesicle, showing small surface projections (arrow). (cdc.gov)
  • Endoplasmic reticulum stress (ERS) has been demonstrated to exhibit a critical role in osteoarthritic chondrocytes. (hindawi.com)
  • The third part of this issue starts by posing the hypothesis of Farhan and colleagues that cellular stress can be the cause of Golgi fragmentation, which in turn amplifies cellular stress and leads to neurodegeneration (Alvarez-Miranda et al.) . (frontiersin.org)
