A schematic representation of the role of eIF1 and eIF5 in regulating stringency of start codon selection in eukaryotes. (Left) mRNA with the mORF AUG start codon in suboptimal context (mAUG*). (Right ...

In contrast to prokaryotes wherein GUG and UUG are permissive start codons, initiation frequencies from non-AUG codons are generally low in eukaryotes, with CUG being considered as strongest. Here, we ...

The eukaryotic 5′ untranslated region (UTR) is critical for ribosome recruitment to the messenger RNA (mRNA) and start codon choice and plays a major role in the control of translation efficiency and ...

The universal genetic code is made up of several codons or triplet bases. The standard code has evolved over time to minimize coding errors. There are a total of 64 codons in the genetic code arising ...

A newly discovered promoter element "start" points to a shared regulatory syntax for controlling transcription initiation in bacteria, archaea, and eukaryotes. Subscribe to our newsletter for the ...
