The ABCs of the ribosome [PDF]

open access: yesNature Structural & Molecular Biology, 2014
An ABC protein that binds the ribosomal exit site suggests a new mechanism for direct regulation of translation in response to changing ATP levels in the cell.

SecM-stalled ribosomes adopt an altered geometry at the peptidyl transferase center [PDF]

open access: yes, 2011
As nascent polypeptide chains are synthesized, they pass through a tunnel in the large ribosomal subunit. Interaction between specific nascent chains and the ribosomal tunnel is used to induce translational stalling for the regulation of gene expression.

Krüppel-like factor 7 influences translation and pathways involved in ribosomal biogenesis in breast cancer

open access: yesBreast Cancer Research, 2022
Background Ribosomal biogenesis and ribosomal proteins have attracted attention in the context of tumor biology in recent years. Instead of being mere translational machineries, ribosomes might play an active role in tumor initiation and progression ...

Yeast Rrp8p, a novel methyltransferase responsible for m1A 645 base modification of 25S rRNA [PDF]

open access: yes, 2012
Ribosomal RNA undergoes various modifications to optimize ribosomal structure and expand the topological potential of RNA. The most common nucleotide modifications in ribosomal RNA (rRNA) are pseudouridylations and 2'-O methylations (Nm), performed by H ...

Gene therapy cures the anemia and lethal bone marrow failure in a mouse model of RPS19-deficient Diamond-Blackfan anemia

open access: yesHaematologica, 2014
Diamond-Blackfan anemia is a congenital erythroid hypoplasia caused by functional haploinsufficiency of genes encoding ribosomal proteins. Mutations involving the ribosomal protein S19 gene are detected in 25% of patients.

Ribosome Builder: A software project to simulate the ribosome

open access: yesComputational Biology and Chemistry, 2005
The Ribosome Builder is a software project that provides tools and techniques to create dynamic models of macromolecular systems from the rapidly growing numbers of atomic structural models. It includes a computer program that allows the user to assemble the multiple molecular components within a 3D space and to define the hypothetical interactions of ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Nop53p is required for late 60S ribosome subunit maturation and nuclear export in yeast [PDF]

open access: yes, 2005
We report that Ypl146cp/Nop53p is associated with pre-60S ribosomal complexes and localized to the nucleolus and nucleoplasm. in cells depleted of Nop53p synthesis of the rRNA components of the 60S ribosomal subunit is severely inhibited, with strikingly

High MRPS23 expression contributes to hepatocellular carcinoma proliferation and indicates poor survival outcomes

open access: yesTumor Biology, 2017
Hepatocellular carcinoma is one of the most prevalent neoplasms and the leading cause of cancer-related mortality worldwide. Mitochondrial ribosomal protein S23 is encoded by a nuclear gene and participates in mitochondrial protein translation ...

Dynamic relationships between ribosomal conformational and RNA positional changes during ribosomal translocation

open access: yesHeliyon, 2016
Ribosomal translocation catalyzed by EF-G hydrolyzing GTP entails multiple conformational changes of ribosome and positional changes of tRNAs and mRNA in the ribosome.
