40S ribosome biogenesis co-factors are essential for gametophyte and embryo development [PDF]

, 2013
Ribosome biogenesis is well described in Saccharomyces cerevisiae. In contrast only very little information is available on this pathway in plants. This study presents the characterization of five putative protein co-factors of ribosome biogenesis in ...

Novel Ribosome-inactivating Protein (RIP) Isolated from Trichosanthes dioica Induces Apoptosis in HeLa Cell Line

International Journal of Bio-Resource and Stress Management, 2021
Ribosome-inactivating proteins (RIPs) are toxic N-glycosidases that depurinate eukaryotic and prokaryotic rRNAs and thus interrupt protein synthesis during translation.

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Saporins - Type 1 Ribosome-inactivating proteins from soapwort (saponaria officinalis L.) [PDF]

, 1995
Ribosome-inactivating proteins (RlPs) are found distributed throughout the plant kingdom. These proteins possess a RNA N-glycosidase activity whereby the depurination of a specific adenine residue from the large ribosomal subunit renders eukaryotic and ...

Improvement of the Pharmacological Properties of Maize RIP by Cysteine-Specific PEGylation

Toxins, 2016
To improve the pharmacological properties of maize ribosome-inactivating protein (maize RIP) for targeting HIV-infected cells, the previously engineered TAT-fused active form of maize RIP (MOD) was further engineered for cysteine-directed PEGylation.

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

FEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Gene sequences encoding ribosome-inactivating proteins from soapwort (Saponaria officinalis L.) [PDF]

, 1991
Ribosome-inactivating proteins (RIPs) are found in a wide variety of plant species. They possess an RNA N-glycosidase activity whereby the removal of a specific adenine residue from 28 S RNA renders a eukaryotic ribosome inactive.

The small-subunit processome is a ribosome assembly intermediate [PDF]

, 2004
The small-subunit (SSU) processome is a large ribonucleoprotein required for the biogenesis of the 18S rRNA and likely corresponds to the terminal knobs visualized by electron microscopy on the 5' end of nascent rRNAs.

Antifungal Activity of Ribosome-Inactivating Proteins

Toxins
The control of crop diseases caused by fungi remains a major problem and there is a need to find effective fungicides that are environmentally friendly. Plants are an excellent source for this purpose because they have developed defense mechanisms to cope with fungal infections.

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.
