WebbIt is possible that +1 ribosomal frameshifting is quite efficient in euplotids, so that the generation of frameshift sites in genes has no, or minimal, effects on the levels of the encoded protein product. In this study we sought to determine if frameshift sites have arisen in Euplotes genes during the evolution of this group.

WebbProgrammed Ribosomal frameshifting is an alternate mechanism of translation to merge proteins encoded by two overlapping open reading frames. The frameshift occurs at low frequency and consists of ribosomes slipping by one base in either the 5' (-1) or 3' (+1) directions during translation. WebbTrinucleotides that form off frame stop codons decrease costs of ribosomal slippages during protein synthesis: protein activity (as a proxy of gene expression, and as measured in experiments using artificial variants of 5′ leading sequences of beta galactosidase in Escherichia coli) increases proportionally to the number of stop motifs in any frame in …
