RsfA (YbeB) proteins are conserved ribosomal silencing factors. [PDF]

PLoS Genetics, 2012
The YbeB (DUF143) family of uncharacterized proteins is encoded by almost all bacterial and eukaryotic genomes but not archaea. While they have been shown to be associated with ribosomes, their molecular function remains unclear.

Involvement of Mitochondrial Ribosomal Proteins in Ribosomal RNA-mediated Protein Folding [PDF]

Journal of Biological Chemistry, 2011
The peptidyl transferase center of the domain V of large ribosomal RNA in the prokaryotic and eukaryotic cytosolic ribosomes acts as general protein folding modulator. We showed earlier that one part of the domain V (RNA1 containing the peptidyl transferase loop) binds unfolded protein and directs it to a folding competent state (FCS) that is released ...

Yeast Polypeptide Exit Tunnel Ribosomal Proteins L17, L35, and L37 are Necessary to Recruit Late-assembling Factors Required for 27SB Pre-rRNA Processing [PDF]

, 2012
Ribosome synthesis involves the coordinated folding and processing of pre-rRNAs with assembly of ribosomal proteins. In eukaryotes, these events are facilitated by trans-acting factors that propel ribosome maturation from the nucleolus to the cytoplasm ...

Integrative systems‐level analysis reveals a contextual crosstalk between hypoxia and global metabolism in human breast tumors

Molecular Oncology, EarlyView.
Breast tumor samples scored for metabolic deregulation (M1 to M3) were given a hypoxia score (HS). The highest HS occurred in patients with strongest metabolic deregulation (M3), supporting tumor aggressiveness. HS correlated with the highest number of metabolic pathways in M1. This suggests hypoxia to be an early event in metabolic deregulation.

The E3 ubiquitin ligase FBXL6 controls the quality of newly synthesized mitochondrial ribosomal proteins

Cell Reports, 2023
Summary: In mammals, about 99% of mitochondrial proteins are synthesized in the cytosol as precursors that are subsequently imported into the organelle. The mitochondrial health and functions rely on an accurate quality control of these imported proteins.

Changes in ribosomal proteins in wheat embryos in the course of grain development and maturation

Acta Societatis Botanicorum Poloniae, 2014
It was found, by comparing the densitometric profiles of ribosomal proteins of wheat embryos in milk and full grain ripeness, that in the process of development and ripening of caryopses the percentual proportion of low molecular weight proteins ...

Extensive evolution of cereal ribosome-inactivating proteins translates into unique structural features, activation mechanisms, and physiological roles [PDF]

, 2017
Ribosome-inactivating proteins (RIPs) are a class of cytotoxic enzymes that can depurinate rRNAs thereby inhibiting protein translation. Although these proteins have also been detected in bacteria, fungi, and even some insects, they are especially ...

Response to neoadjuvant chemotherapy in early breast cancers is associated with epithelial–mesenchymal transition and tumor‐infiltrating lymphocytes

Molecular Oncology, EarlyView.
Epithelial–mesenchymal transition (EMT) and tumor‐infiltrating lymphocytes (TILs) are associated with early breast cancer response to neoadjuvant chemotherapy (NAC). This study evaluated EMT and TIL shifts, with immunofluorescence and RNA sequencing, at diagnosis and in residual tumors as potential biomarkers associated with treatment response.

Transcriptome‐wide analysis of circRNA and RBP profiles and their molecular relevance for GBM

Molecular Oncology, EarlyView.
CircRNAs are differentially expressed in glioblastoma primary tumors and might serve as therapeutic targets and diagnostic markers. The investigation of circRNA and RNA‐binding proteins (RBPs) interactions shows that distinct RBPs play a role in circRNA biogenesis and function.
