Project

Stop codon readthrough lessons from the tRNA anti-codon stem. (GF23-08669L)

to be employed in programmed stop codon readthrough in all organisms. Here, in the three and attempt to solve the structure of an 80S ribosome reading through a stop codon.......

Anaerobic ciliates as a model group to study alternative nuclear genetic codes (GA25-17400S)

these aberrations involve reassignments of stop codons. The most frequent is the reassignment of the UAG and UAA (=UAR) codons. It originated at least 14 times independently assay, we will trace how UAR <...

Blastocrithidia and Trypanosoma as optimal models for testing the emergence and features of alternative genetic codes (GA22-14356S)

and eukaryotic genomes. The most common deviation represents a stop-to-sense codon reassignment. We have recently described a novel protist, Blastocrithidia nonstop, in which all three stop codons specify...

Structural and biochemical insights into miscoding by the eukaryotic ribosome. (GA20-00579S)

Recent studies revealed the involvement of glutamine tRNA in stop codon readthrough. Surprisingly, the efficiency of readthrough is not equal for all Glu-tRNA isoforms. The highest readthrough is manifested by the M isoform; i.e. t...

Deciphering molecular details of the stringent decoding of the AUG start codon during eukaryotic translation initiation. (GAP305/10/0335)

Start codon selection is a key step in translation as it sets the reading frame for decoding. The 40S ribosome has to scan the mRNA’s 5' UTR in its search for the AUG start codon and respond to a set of not well-understood signals t...
