... the endoplasmic reticulum (ER). This newly identified quality control pathway employs components of the cytosolic ribosome-associated quality control (RQC) machinery but differs from canonical RQC in that it responds to biogenesis state of the substrate rather than mRNA aberrations. This ER-associated...

...Stephen DiGiuseppe; Madeline G. Rollins; Helen Astar; Natalia Khalatyan; Jeffrey N. Savas; Derek Walsh ABSTRACT Ribosomes are often viewed as protein synthesis machines that lack intrinsic regulatory capacity. However, studies have established that ribosomes can functionally diversify through...

...Valentina Sirri; Alice Grob; Jérémy Berthelet; Nathalie Jourdan; Pascal Roussel ABSTRACT In humans, ribosome biogenesis mainly occurs in nucleoli following two alternative pre-rRNA processing pathways differing in the order in which cleavages take place but not by the sites of cleavage. To uncover...

... is optimized to regulate interactions with eIF6, a eukaryotic initiation factor that controls 60S biogenesis and 80S ribosome assembly. Separately, phylogenetics revealed that, despite broad sequence divergence of the loop, there is striking conservation of negatively charged residues amongst...

... ribosomes. Maintaining these components requires gene expression to be coordinated between the nucleo-cytoplasmic compartment and mitochondria in order to monitor organelle homeostasis and to integrate the responses to the physiological and developmental demands of the cell. Surprisingly, the parameters...

...Franziska Thomas; Ulrike Kutay The production of ribosomes constitutes a major biosynthetic task for cells. Eukaryotic small and large ribosomal subunits are assembled in the nucleolus and independently exported to the cytoplasm. Most nuclear export pathways require RanGTP-binding export receptors...

... ) fractionates in ribosome-free fractions of light density, Stau2 59 and Stau2 52 are found in high-density complexes. These complexes are resistant to EDTA and to non-ionic detergent. For the first time, we also provide evidence for an interaction of some Stau2 isoforms with ribosomes, thus pointing to an...

...Terence I. Moy; Pamela A. Silver Eukaryotic ribosome biogenesis requires multiple steps of nuclear transport because ribosomes are assembled in the nucleus while protein synthesis occurs in the cytoplasm. Using an in situ RNA localization assay in the yeast Saccharomyces cerevisiae , we determined...
