(1) Background: A premature termination codon (PTC) can be induced by a type of point mutation known as a nonsense mutation, which occurs within the coding region. Approximately 3.8% of human cancer patients have nonsense mutations of p53.

Intranuclear degradation of nonsense codon‐containing mRNA [PDF]
Most vertebrate mRNAs with premature termination codons (PTCs) are specifically recognized and degraded by a process referred to as nonsense‐mediated mRNA decay (NMD) while still associated with the nucleus. However, it is still a matter of debate whether PTCs can be identified by intranuclear scanning or only by ribosomes on the cytoplasmic side of ...

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.

2,6-Diaminopurine as a highly potent corrector of UGA nonsense mutations
Nonsense mutations can be corrected by several molecules that activate readthrough of premature termination codon. Here, the authors report that 2,6-diaminopurine efficiently corrects UGA nonsense mutations with no significant toxicity.

A G542X cystic fibrosis mouse model for examining nonsense mutation directed therapies. [PDF]
Nonsense mutations are present in 10% of patients with CF, produce a premature termination codon in CFTR mRNA causing early termination of translation, and lead to lack of CFTR function.

Nonsense mediated decay downregulates conserved alternatively spliced ABCC4 transcripts bearing nonsense codons [PDF]
Drug transporters are an important part of the defense of cells against cytotoxic agents. One major group of transporters is known as multidrug resistance associated proteins (MRP; ABCC gene family). The MRPs belong to the ATP binding cassette transporter superfamily. One family member, ABCC4 (also known as MRP4) functions as a cellular efflux pump for

Background Nonsense-mediated decay is a mechanism that degrades mRNAs with a premature termination codon. That some exons have premature termination codons at fixation is paradoxical: why make a transcript if it is only to be destroyed?

Selection on Position of Nonsense Codons in Introns [PDF]
Abstract Introns occasionally remain in mature messenger RNAs (mRNAs) due to splicing errors and the translated, aberrant proteins that result represent a metabolic cost and may have other deleterious consequences. The nonsense-mediated decay (NMD) pathway degrades aberrant mRNAs, which it recognizes by the presence of an in-frame ...

Codon usage in vertebrates is associated with a low risk of acquiring nonsense mutations
Background Codon usage in genomes is biased towards specific subsets of codons. Codon usage bias affects translational speed and accuracy, and it is associated with the tRNA levels and the GC content of the genome.

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.
