Pharmaceuticals Promoting Premature Termination Codon Readthrough: Progress in Development
Biomolecules, 2023 Around 11% of all known gene lesions causing human genetic diseases are nonsense mutations that introduce a premature stop codon (PTC) into the protein-coding gene sequence.

A 212-nt long RNA structure in the Tobacco necrosis virus-D RNA genome is resistant to Xrn degradation [PDF]
, 2019 Plus-strand RNA viruses can accumulate viral RNA degradation products during infections. Some of these decay intermediates are generated by the cytosolic 5′-to-3′ exoribonuclease Xrn1 (mammals and yeast) or Xrn4 (plants) and are formed when the enzyme ...

RNA pseudoknots: Translational frameshifting and readthrough on viral RNAs [PDF]
Virus Genes, 1990 Ribosomal frameshifting on retroviral RNAs has been proposed to be mediated by slippage of two adjacent tRNAs into the -1 direction at a specific heptanucleotide sequence. Here we report a computer-aided analysis of the structure around the established or putative frameshift sites in a number of retroviral, coronaviral, toroviral, and luteoviral RNAs ...

Cryptic transcripts from a ubiquitous plasmid origin of replication confound tests for cis-regulatory function. [PDF]
, 2012 A vast amount of research on the regulation of gene expression has relied on plasmid reporter assays. In this study, we show that plasmids widely used for this purpose constitutively produce substantial amounts of RNA from a TATA-containing cryptic ...

Translational readthrough goes unseen by natural selection [PDF]
, 2019 AbstractOccasionally during protein synthesis, the ribosome bypasses the stop codon and continues translation to the next stop codon in frame. This error is called translational readthrough (TR). Earlier research suggest that TR is a relatively common error, in several taxa, yet the evolutionary relevance of this translational error is still unclear ...

Pharmacophore-Based Design of New Chemical Scaffolds as Translational Readthrough-Inducing Drugs (TRIDs). [PDF]
ACS Med Chem Lett, 2020 Translational readthrough-inducing drugs (TRIDs) rescue the functional full-length protein expression in genetic diseases, such as cystic fibrosis, caused by premature termination codons (PTCs). Small molecules have been developed as TRIDs to trick the ribosomal machinery during recognition of the PTC. Herein we report a computational study to identify

The 5 ' untranslated region of protein kinase C delta directs translation by an internal ribosome entry segment that is most active in densely growing cells and during apoptosis. [PDF]
, 2002 Protein kinase Cdelta (PKCdelta) is a member of the PKC family of phospholipid-dependent serine/threonine kinases and is involved in cell proliferation, apoptosis, and differentiation.

Multiple Localization by Functional Translational Readthrough
, 2018 In a compartmentalized cell, correct protein localization is crucial for function of virtually all cellular processes. From the cytoplasm as a starting point, proteins are imported into organelles by specific targeting signals. Many proteins, however, act in more than one cellular compartment.
