It was presumed that most frameshifts would yield non-functional, truncated or cytotoxic products. In this study, we report that in E. coli, a frameshift β-lactamase (bla) gene is still functional if all of the inner stop codons were readthrough or replaced by a sense codon. By analyzing a large dataset including all available protein coding genes in major model organisms, it is demonstrated that in any species, and in any protein-coding genes, the three translational products from the three different reading frames, are always similar to each other and with constant ~50% similarities and ~100% coverages, and the similarities is predefined by the genetic code rather than the sequences themselves. It is likely that a coding gene can be translated into three isoforms from each of the three reading frames, we propose a new gene expression paradigm, “one transcript, three translations”, which is an amendment to the traditional “one gene, one/multiple peptides” hypotheses. Finally, we concluded that the genetic code was optimized for frameshift tolerating in the early evolution, which endows every protein coding gene a character of shiftability, an inherent and everlasting ability to tolerate frameshift mutations, and serves as an innate mechanism for cells to deal with the frameshift problem.","is_dataset_classified":null,"base_score":0.0,"endowment":0.0,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"21097893","pmcid":null,"openalex_id":"https://openalex.org/W4252082584","authors":[],"funders":[],"total_grants":0,"fwci":null,"citation_percentile":null,"influential_citations":0,"citation_trend":[],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://doi.org/10.7287/peerj.preprints.806v1/supp-2","host_type":""},{"url":"https://doi.org/10.7287/peerj.preprints.806v1/supp-2","host_type":""}],"fields_of_study":["RNA and protein synthesis mechanisms","Genomics and Phylogenetic Studies","Bacterial Genetics and Biotechnology"],"mesh_terms":[],"keywords":["Frameshift mutation","Gene","Reading frame","Open reading frame","Stop codon","Genetics","Coding region","Genetic code","Biology","Codon usage bias","Computational biology","Mutation","Genome","Peptide sequence"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Quality Education"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-30T02:11:02.106252Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
