Intracellular trafficking of lysosomal membrane proteins
BioEssays, 1996AbstractLysosomes are the site of degradation of obsolete intracellular material during autophagy and of extracellular macromolecules following endocytosis and phagocytosis. The membrane of lysosomes and late endosomes is enriched in highly glycosylated transmembrane proteins of largely unknown function.

Calcium Pumps in the Plasma and Intracellular Membranes
1992ATP-powered Ca2+ pumps have now been extensively characterized in the plasma membrane of all eukaryotic cells, and in the membranes of fast and slow twitch sarcoplasmic reticulum (SR) and those of endoplasmic reticulum (ER). They have also been described in other membranes, e.g., the nuclear envelope and the lysosomes, but their characterization in the

CD95 ligation and intracellular membrane flow
Biochemical Journal, 2008Whereas ligation of the CD95 death receptor in the plasma membrane of so-called type I cells leads to a direct caspase 8-dependent activation of downstream effector caspases, mitochondrial amplification of caspase 8-derived signals is required in so-called type II cells in order to execute apoptotic cell death.

Specific localization of Rabs at intracellular membranes
Biochemical Society Transactions, 2012Despite over two decades of research, the mechanism of Rab targeting to specific intracellular membranes is still not completely understood. Present evidence suggests that the original hypothesis that the message for targeting resides solely in the hypervariable C-terminus is incorrect, and a second mechanism involving a GDF [GDI (guanine-nucleotide ...

Coat proteins in intracellular membrane transport
Current Opinion in Cell Biology, 1994Transport of newly synthesized material from the endoplasmic reticulum (ER) towards the Golgi complex, through the Golgi cisternae, and out of the trans-Golgi network (TGN) is thought to be mediated by vesicular carriers. Different types of vesicle are involved in this biosynthetic membrane traffic.

Problems in intracellular membrane traffic.
Ciba Foundation symposium, 1982Eukaryotic cells operate an extensive and well regulated traffic of membrane-bound vesicles to: (a) transport intracellularly, and eventually discharge by exocytosis, macromolecular products; (b) take up by endocytosis molecules and particles from the environment; (c) transport macromolecules across epithelial barriers; and (d) move membranes from ...

The Organizing Potential of Sphingolipids in Intracellular Membrane Transport
Physiological Reviews, 2001Eukaryotes are characterized by endomembranes that are connected by vesicular transport along secretory and endocytic pathways. The compositional differences between the various cellular membranes are maintained by sorting events, and it has long been believed that sorting is based solely on protein-protein interactions.

Attachment of ribosome crystals to intracellular membranes
Journal of Molecular Biology, 1979The attachment to membranes of ribosome crystals formed by cooling lizard oocytes and chick embryos has been investigated by electron microscopy of whole cells and by biochemical and structural experiments, using the cross-linking reagent glutaraldehyde.

Journal of Electron Microscopy, 1992
The ultrastructure of the intracellular membranous system in rat hepatocytes was observed three dimensionally with a scanning electron microscope using the aldehyde prefix osmium-dimethyl sulfoxide-osmium method. Intracellular organelles were clearly observed in three dimensions, and direct connection of tubular structures with the bile canalicular ...
