Protein transport from the endoplasmic reticulum to the Golgi apparatus.
As the first step of protein transport along the biosynthetic (secretory/exocytotic) pathway, transport from the endoplasmic reticulum (ER) to the Golgi apparatus has received much attention over the past several decades. The general structural organization underlying this transport process is becoming more defined. The major protein components participating in the budding, pre-docking, and doc...
متن کاملTraffic between the plant endoplasmic reticulum and Golgi apparatus: to the Golgi and beyond.
Significant advances have been made in recent years that have increased our understanding of the trafficking to and from membranes that are functionally linked to the Golgi apparatus in plants. New routes from the Golgi to organelles outside the secretory pathway are now being identified, revealing the importance of the Golgi apparatus as a major sorting station in the plant cell. This review d...
متن کاملMisfolded growth hormone causes fragmentation of the Golgi apparatus and disrupts endoplasmic reticulum-to-Golgi traffic.
In some individuals with autosomal dominant isolated growth hormone deficiency, one copy of growth hormone lacks amino acids 32-71 and is severely misfolded. We transfected COS7 cells with either wild-type human growth hormone or Delta 32-71 growth hormone and investigated subcellular localization of growth hormone and other proteins. Delta 32-71 growth hormone was retained in the endoplasmic r...
متن کاملThe Ubiquitin Ligase CBLC Maintains the Network Organization of the Golgi Apparatus
The Golgi apparatus plays a pivotal role in the sorting and post-translational modifications of secreted and membrane proteins. In mammalian cells, the Golgi is organized in stacks of cisternae linked together to form a network with a ribbon shape. Regulation of Golgi ribbon formation is poorly understood. Here we find in an image-based RNAi screen that depletion of the ubiquitin-ligase CBLC in...
متن کاملThe role of microtubules in transport between the endoplasmic reticulum and Golgi apparatus in mammalian cells.
The organization of intracellular compartments and the transfer of components between them are central to the correct functioning of mammalian cells. Proteins and lipids are transferred between compartments by the formation, movement and subsequent specific fusion of transport intermediates. These vesicles and membrane clusters must be coupled to the cytoskeleton and to motor proteins that driv...
