Cell death or survival: Insights into the role of mRNA translational control

N Bhatter, SE Dmitriev, P Ivanov - Seminars in Cell & Developmental …, 2024 - Elsevier
Cellular stress is an intrinsic part of cell physiology that underlines cell survival or death. The
ability of mammalian cells to regulate global protein synthesis (aka translational control) …

Does functional specialization of ribosomes really exist?

MB Ferretti, K Karbstein - Rna, 2019 - rnajournal.cshlp.org
It has recently become clear that ribosomes are much more heterogeneous than previously
thought, with diversity arising from rRNA sequence and modifications, ribosomal protein …

Nitrogen limitation reveals large reserves in metabolic and translational capacities of yeast

R Yu, K Campbell, R Pereira, J Björkeroth, Q Qi… - Nature …, 2020 - nature.com
Cells maintain reserves in their metabolic and translational capacities as a strategy to
quickly respond to changing environments. Here we quantify these reserves by stepwise …

The chaperone Tsr2 regulates Rps26 release and reincorporation from mature ribosomes to enable a reversible, ribosome-mediated response to stress

YM Yang, K Karbstein - Science Advances, 2022 - science.org
Although ribosome assembly is quality controlled to maintain protein homeostasis, different
ribosome populations have been described. How these form, especially under stress …

Duplicated ribosomal protein paralogs promote alternative translation and drug resistance

M Malik Ghulam, M Catala, G Reulet, MS Scott… - Nature …, 2022 - nature.com
Ribosomes are often seen as monolithic machines produced from uniformly regulated
genes. However, in yeast most ribosomal proteins come from duplicated genes. Here, we …

Proteome diversification by mRNA translation in cancer

A kinase-dependent checkpoint prevents escape of immature ribosomes into the translating pool

MD Parker, JC Collins, B Korona, H Ghalei… - PLoS …, 2019 - journals.plos.org
Premature release of nascent ribosomes into the translating pool must be prevented
because these do not support viability and may be prone to mistakes. Here, we show that …
