Frameshifts in Tandem Repeats: Consequences on Protein Physicochemical Properties and Function

Open access

Preprint — published as 10.1111/febs.70273 · Paper page

Abstract

The genetic code uses three-nucleotide units to encode each amino acid in proteins. Insertions or deletions of nucleotides not divisible by three shift the reading frames, resulting in significantly different protein sequences. These events are disruptive but can also create variability important for evolution. Previous studies suggest that genetic code and gene sequences evolve to minimize frameshift effects, maintaining similar physicochemical properties to their reference proteins. Here, we focused on tandem repeat sequences, known as frameshift hotspots. Using cutting-edge bioinformatics tools, we compared reference and frameshifted protein sequences within tandem repeats across 50 prokaryotic and eukaryotic proteomes. Our analysis revealed several intriguing sequence-structure-function correlations. We showed that in contrast to the general tendency, frameshifts within these regions, especially with short repeats, lead to significant changes: increased hydrophobicity and arginine content, new aggregation-prone and transmembrane regions. Overall, frameshifts have stronger effects on tandem repeat regions compared to non-repetitive sequences, and therefore can be a primary cause of altered functions, cellular localization, and the development of various pathologies.

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.
