Nuclear 80S Ribosomes Present Across the Stages of Cell Cycle in Drosophila Melanogaster Cells

open access: yesUMYU Journal of Microbiology Research, 2023
Nuclear translation has been a subject of controversy between scientists for over 5 decades. Despite the existence of evidence to the contrary, most biologists agree that translation exclusively takes place in the cytoplasm of eukaryotes.

Preparation of Biologically Active Arabidopsis Ribosomes and Comparison with Yeast Ribosomes for Binding to a tRNA-Mimic that Enhances Translation of Plant Plus-Strand RNA Viruses

open access: yesFrontiers in Plant Science, 2013
Isolation of biologically active cell components from multicellular eukaryotic organisms often poses difficult challenges such as low yields and inability to retain the integrity and functionality of the purified compound. We previously identified a cap-

Identification and characterization of yeast SNF1 kinase homologs in Leishmania major

open access: yesFrontiers in Molecular Biosciences
BackgroundSucrose Non Fermenting1 (SNF1) constitutes a family of protein kinases conserved in eukaryotes, plants, and fungi. SNF1 has been known to play a crucial role in stress adaptation and metabolism, enabling organisms to respond to changing ...

The influence of exogenous spermidine on polysomes and RNase activity in wheat leaves under water stress conditions short communication

open access: yesActa Societatis Botanicorum Poloniae, 2014
It was found that spermidine (5mM) delivered to wheat seedlings through their roots prior to water stress affected the state of polysomes and ribosomes under water stress conditions, which was manifested in stabilization of 80 S ribosomes and in ...

microRNAs Mediated Regulation of the Ribosomal Proteins and its Consequences on the Global Translation of Proteins

open access: yesCells, 2021
Ribosomal proteins (RPs) are mostly derived from the energy-consuming enzyme families such as ATP-dependent RNA helicases, AAA-ATPases, GTPases and kinases, and are important structural components of the ribosome, which is a supramolecular ...

How bacteria keep proteins moving

open access: yeseLife, 2017
Bacteria contain large numbers of negatively-charged proteins to avoid the electrostatic interactions with ribosomes that would dramatically reduce protein diffusion.

The metabolism of aged seeds. The free and membrane-bound polyribosomes of germinating rye grains of different ages

open access: yesActa Societatis Botanicorum Poloniae, 2014
Grains of winter rye harvested in 1976, 1978, 1982 and 1984 were studied. Free and membrane-bound polyribosomes were isolated from embryos of imbibing and germinating grains.

A working model for cytoplasmic assembly of H/ACA snoRNPs

open access: yesFEBS Letters, EarlyView.
Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes

open access: yesFEBS Letters, EarlyView.
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

Adaptation of Translational Machinery in Malaria Parasites to Accommodate Translation of Poly-Adenosine Stretches Throughout Its Life Cycle

open access: yesFrontiers in Microbiology, 2019
Malaria is caused by unicellular apicomplexan parasites of the genus Plasmodium, which includes the major human parasite Plasmodium falciparum. The complex cycle of the malaria parasite in both mosquito and human hosts has been studied extensively. There
