The scanning mechanism of eukaryotic translation initiation

AG Hinnebusch - Annual review of biochemistry, 2014 - annualreviews.org
In eukaryotes, the translation initiation codon is generally identified by the scanning
mechanism, wherein every triplet in the messenger RNA leader is inspected for …

Upstream open reading frames differentially regulate gene-specific translation in the integrated stress response

SK Young, RC Wek - Journal of Biological Chemistry, 2016 - ASBMB
Translation regulation largely occurs during initiation, which features ribosome assembly
onto mRNAs and selection of the translation start site. Short, upstream ORFs (uORFs) …

Translation termination and ribosome recycling in eukaryotes

CUT Hellen - Cold Spring Harbor perspectives in biology, 2018 - cshperspectives.cshlp.org
Termination of mRNA translation occurs when a stop codon enters the A site of the
ribosome, and in eukaryotes is mediated by release factors eRF1 and eRF3, which form a …

Molecular mechanism of scanning and start codon selection in eukaryotes

AG Hinnebusch - Microbiology and Molecular Biology Reviews, 2011 - Am Soc Microbiol
The correct translation of mRNA depends critically on the ability to initiate at the right AUG
codon. For most mRNAs in eukaryotic cells, this is accomplished by the scanning …
