Suppressing nonsense--a surprising function for 5-azacytidine. [PDF]
In this issue of EMBO Molecular Medicine, Bhuvanagiri et al report on a chemical means to convert molecular junk into gold. They identify a chemical inhibitor of a quality control pathway that is best known for its ability to clear cells of rubbish, but ...

Directional Next-Generation RNA Sequencing and Examination of Premature Termination Codon Mutations in Endoglin/Hereditary Haemorrhagic Telangiectasia [PDF]
Hereditary haemorrhagic telangiectasia (HHT) is a disease characterised by abnormal vascular structures, and most commonly caused by mutations in ENG, ACVRL1 or SMAD4 encoding endothelial cell-expressed proteins involved in TGF-β superfamily signalling ...

During mRNA translation, nascent peptides with certain specific sequences cause arrest of ribosomes that have synthesized themselves. In some cases, such ribosomal arrest is coupled with mRNA decay.

The influence of the reading context upon the suppression of nonsense codons
We have examined the response of phage T4 nonsense mutations located at various sites within the same cistron to different suppression agents. A wide range of suppression efficiency is found for both ochre (UAA) and amber (UAG) mutations under conditions where suppression provides a measurement of the amount of chain propagation past the mutated site ...

Identification and functional analysis of novel phosphorylation sites in the RNA surveillance protein Upf1. [PDF]
One third of inherited genetic diseases are caused by mRNAs harboring premature termination codons as a result of nonsense mutations. These aberrant mRNAs are degraded by the Nonsense-Mediated mRNA Decay (NMD) pathway.

Recognition of Nonsense Codons in Mammalian Cells [PDF]
The tritiated trinucleotide UGA was used in a binding assay to detect transfer RNAs that recognize this nonsense codon from calf-liver cells. Acylation of transfer RNA with labeled amino acids and determination of codon responses of aminoacyl-tRNAs demonstrate that a species of seryl-tRNA and a species of arginyl-tRNA recognize the codon UGA.

Recoding of Nonsense Mutation as a Pharmacological Strategy
Approximately 11% of genetic human diseases are caused by nonsense mutations that introduce a premature termination codon (PTC) into the coding sequence. The PTC results in the production of a potentially harmful shortened polypeptide and activation of a

Mutations in the RB1 Gene in Argentine Retinoblastoma Patients and Uncommon Clinical Presentations [PDF]
Background: Retinoblastoma, the most common ocular cancer of childhood, is caused by inactivation of the RB1 tumor suppressor gene in the developing retina.

Evolution of termination codons of proteins and the TAG-TGA paradox
In most eukaryotes and prokaryotes TGA is used at a significantly higher frequency than TAG as termination codon of protein-coding genes. Although this phenomenon has been recognized several years ago, there is no generally accepted explanation for the ...

We recently described an orthogonal initiator tRNA (itRNATy2) that can initiate protein synthesis with noncanonical amino acids (ncAAs) in response to the UAG nonsense codon. Here we report that a mutant of itRNATy2 (itRNATy2AUA) can efficiently initiate
