Golgi biogenesis.
The Golgi is an essential membrane-bound organelle in the secretary pathway of eukaryotic cells. In mammalian cells, the Golgi stacks are integrated into a continuous perinuclear ribbon, which poses a challenge for the daughter cells to inherit this membrane organelle during cell division. To facilitate proper partitioning, the mammalian Golgi ribbon is disassembled into vesicles in early mitos...
متن کاملIron-sulfur-protein biogenesis in eukaryotes.
Iron-sulfur (Fe-S) clusters (ISCs) are versatile, ancient co-factors of proteins that are involved in electron transport, enzyme catalysis and regulation of gene expression. The synthesis of ISCs and their insertion into apoproteins involves the function of complex cellular machineries. In eukaryotes, the mitochondrial ISC-assembly machinery is involved in the maturation of all cellular iron-su...
متن کاملGolgi Complex: Biogenesis de novo?
Whether Golgi biogenesis occurs by self-assembly or around a pre-existing template is currently a matter of debate. Recent studies have shown that Golgi structural proteins are more dynamic than previously thought, suggesting that self-assembly of the Golgi complex may be possible.
متن کاملRecent advances in understanding Golgi biogenesis
The Golgi complex is a central processing station for proteins traversing the secretory pathway, yet we are still learning how this compartment is constructed and how cargo moves through it. Recent experiments suggest a key role for Ras-like Rab GTPases and provide important new ideas for how the Golgi may function.
متن کاملBiogenesis of the plant Golgi apparatus.
It has long been assumed that the individual cisternal stacks that comprise the plant Golgi apparatus multiply by some kind of fission process. However, more recently, it has been demonstrated that the Golgi apparatus can be experimentally disassembled and the reformation process from the ER (endoplasmic reticulum) monitored sequentially using confocal fluorescence and electron microscopy. Some...
