Eukaryotic start and stop translation sites

Open access

Abstract

Sequences flanking translational initiation and termination sites have been compiled and statistically analyzed for various eukaryotic taxonomic groups. A few key similarities between taxonomic groups support conserved mechanisms of initiation and termination. However, a high degree of sequence variation at these sites within and between various eukaryotic groups suggest that translation may be modulated for many mRNAs. Multipositional analysis of di-, tri-, and quadrinucleotide sequences flanking start/stop sites indicate significant biases. In particular, strong tri-nucleotide biases are observed at the -3, -2, and -1 positions upstream of the start codon. These biases and the interspecific variation in nucleotide preferences at these three positions have lead us to propose a revised model of the interaction of the 18S ribosomal RNA with the mRNA at the site of translation initiation. Unusually strong biases against the CG dinucleotide immediately downstream of termination codons suggest that they may lead to faulty termination and/or failure of the ribosome to disassociate from the mRNA.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
