The effect of nonsense codons on splicing: a genomic analysis.
The phenomenon of nonsense-associated altered splicing raises the possibility that the recognition of in-frame nonsense codons is used generally for exon identification during pre-mRNA splicing. However, nonsense codon frequencies in pseudo exons and in regions flanking 5' splice sites are no greater than that expected by chance, arguing against the widespread use of this strategy as a means of...

15 صفحه اولBinary specification of nonsense codons by splicing and cytoplasmic translation.
Premature translation termination codons resulting from nonsense or frameshift mutations are common causes of genetic disorders. Complications arising from the synthesis of C-terminally truncated polypeptides can be avoided by 'nonsense-mediated decay' of the mutant mRNAs. Premature termination codons in the beta-globin mRNA cause the common recessive form of beta-thalassemia when the affected ...
متن کاملInteraction of nonsense suppressor tRNAs and codon nonsense mutations or termination codons
Codon nonsense mutations include amber, ochre, or opal mutations according to termination codon consisting of three types (TAG, TAA and TGA). Codon nonsense mutations are also divided into natural and artificial mutations. We discussed the interaction of codon nonsense mutations and suppressor tRNAs in vitro and in vivo. Nonsense suppressions do not only happen in prokaryotes but also in eukary...
متن کاملSelection at the wobble position of codons read by the same tRNA in Saccharomyces cerevisiae.
The transfer RNA gene complement of Saccharomyces cerevisiae was utilized for a whole-genome analysis of the deviation from a neutral usage of pyrimidine-ending cognate codons, that is, codons read by a single tRNA species having either inosine or guanosine as the first anticodon base. Mutational pressure at the wobble position was estimated from the base composition of the noncoding portion of...
