Structures of translationally inactive mammalian ribosomes
The cellular levels and activities of ribosomes directly regulate gene expression during numerous physiological processes. The mechanisms that globally repress translation are incompletely understood.

Compartmentalisation and localisation of the translation initiation factor (eIF) 4F complex in normally growing fibroblasts [PDF]
Previous observations of association of mRNAs and ribosomes with subcellular structures highlight the importance of localised translation. However, little is known regarding associations between eukaryotic translation initiation factors and cellular ...

Characterization of ribosome heterogeneity during endothelial to hematopoietic transition
The panorama of ribosome heterogeneity during embryonic hematopoiesis has not yet been portrayed. In this study, utilizing dual‐omics data, the heterogenous dynamic of ribosome during endothelial‐to‐hematopoietic transition has been systemically described. Moreover, stage‐specific upregulation and peripheral localization of RPL27 and RACK1 in hemogenic

How Cancer Exploits Ribosomal RNA Biogenesis: A Journey beyond the Boundaries of rRNA Transcription
The generation of new ribosomes is a coordinated process essential to sustain cell growth. As such, it is tightly regulated according to cell needs. As cancer cells require intense protein translation to ensure their enhanced growth rate, they exploit ...

RACK1 Specifically Regulates Translation through Its Binding to Ribosomes
The translational capability of ribosomes deprived of specific nonfundamental ribosomal proteins may be altered. Physiological mechanisms are scanty, and it is unclear whether free ribosomal proteins can cross talk with the signaling machinery.

Liver‐specific lncRNAs associated with liver cancers
Long non‐coding RNAs (lncRNAs) are regulatory molecules with various functions. They are more tissue‐specific than proteins and can be used as potential biomarkers, particularly in cancer diagnostics and prognosis. In this review, we have systematically compiled all lncRNAs with exclusive expression in the human liver, verified their liver specificity ...

Functions of ribosomal proteins in assembly of eukaryotic ribosomes in vivo.
The proteome of cells is synthesized by ribosomes, complex ribonucleoproteins that in eukaryotes contain 79-80 proteins and four ribosomal RNAs (rRNAs) more than 5,400 nucleotides long.

The E3 ubiquitin ligase, RNF219, suppresses CNOT6L expression to exhibit antiproliferative activity
We identified RNF219 as a CCR4‐NOT complex‐interacting E3 ubiquitin ligase that targets the CCR4‐NOT subunit CNOT6L for ubiquitination. RNF219 directly binds to the DUF3819 domain of CNOT1 through its putative α‐helix spanning amino acids 521–542. Our findings also suggest that antiproliferative activity of RNF219 is at least partially mediated by ...

Translating the Game: Ribosomes as Active Players
Ribosomes have been long considered as executors of the translational program. The fact that ribosomes can control the translation of specific mRNAs or entire cellular programs is often neglected.

Stoichiometry and Change of the mRNA Closed-Loop Factors as Translating Ribosomes Transit from Initiation to Elongation [PDF]
Protein synthesis is a highly efficient process and is under exacting control. Yet, the actual abundance of translation factors present in translating complexes and how these abundances change during the transit of a ribosome across an mRNA remains ...
