Translation initiation factor eIF3 promotes programmed stop codon readthrough. [PDF]
Programmed stop codon readthrough is a post-transcription regulatory mechanism specifically increasing proteome diversity by creating a pool of C-terminally extended proteins.

Nonsense Codons Trigger an RNA Partitioning Shift [PDF]
T-cell receptor-beta (TCRbeta) genes naturally acquire premature termination codons (PTCs) as a result of programmed gene rearrangements. PTC-bearing TCRbeta transcripts are dramatically down-regulated to protect T-cells from the deleterious effects of the truncated proteins that would otherwise be produced.

Optimized approach for the identification of highly efficient correctors of nonsense mutations in human diseases. [PDF]
About 10% of patients with a genetic disease carry a nonsense mutation causing their pathology. A strategy for correcting nonsense mutations is premature termination codon (PTC) readthrough, i.e.

Identifying Potent Nonsense-Mediated mRNA Decay Inhibitors with a Novel Screening System
Nonsense-mediated mRNA decay (NMD) is a quality control mechanism that degrades mRNAs carrying a premature termination codon. Its inhibition, alone or in combination with other approaches, could be exploited to develop therapies for genetic diseases ...

Nonsense and sense suppression abilities of original and derivative Methanosarcina mazei pyrrolysyl-tRNA synthetase-tRNA(Pyl) pairs in the Escherichia coli BL21(DE3) cell strain. [PDF]
Systematic studies of nonsense and sense suppression of the original and three derivative Methanosarcina mazei PylRS-tRNA(Pyl) pairs and cross recognition between nonsense codons and various tRNA(Pyl) anticodons in the Escherichia coli BL21(DE3) cell ...

Transcriptional Silencing of Nonsense Codon-Containing Immunoglobulin Minigenes [PDF]
Cells possess mechanisms to prevent synthesis of potentially deleterious truncated proteins caused by premature translation-termination codons (PTCs). Here, we show that PTCs can induce silencing of transcription of its cognate gene. We demonstrate for immunoglobulin (Ig)-mu minigenes expressed in HeLa cells that this transcriptional silencing is PTC ...

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 ...

Molecular approaches fighting nonsense [PDF]
: Nonsense mutations are the result of single nucleotide substitutions in the DNA that change a sense codon (coding for an amino acid) to a nonsense or premature termination codon (PTC) within the coding region of the mRNA [...]

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
