(i) Structural and Biochemical analyses for the complexes of omnipotent archaeal translation elongation factor (aEF1alpha) with tRNA mimicry proteins (aRF1, aPelota). (ii) Genetic analyses for the functionality of tRNA-mimicking complex on the ribosome. These analyses revealed that the specific regions are located in the binding interface of the tRNA-mimicking complexes and that a novel functional site adjacent to the codon recognition site, on the tip domain that mimics the tRNA anticodon-loop is crucial for their functionality. These novel domains likely participate in decoding and mRNA surveillance, coupled with the GTPase switch function on the ribosome.","funder_award_id":"23657071","funder":{"id":"https://openalex.org/F4320334764","display_name":"Japan Society for the Promotion of Science","doi":"10.13039/501100001691"},"funded_outputs":["https://openalex.org/W1973307692","https://openalex.org/W2005005285","https://openalex.org/W2019923657","https://openalex.org/W2035374324","https://openalex.org/W2075949504","https://openalex.org/W2123360206"],"funded_outputs_count":6,"parent_awards":[],"sub_awards":[],"sub_awards_count":0,"amount":3770000.0,"currency":"JPY","amount_usd":null,"amount_usd_basis":null,"recipients":[],"recipient_countries":[],"recipient_regions":[],"research_scope":{"is_research":true,"basis":"funder_default","tier":1},"funding_type":"research","funder_scheme":"Grant-in-Aid for Challenging Exploratory Research","start_date":null,"end_date":null,"start_year":null,"end_year":null,"landing_page_url":"https://kaken.nii.ac.jp/en/grant/KAKENHI-PROJECT-23657071/","doi":null,"provenance":"kaken","lead_investigator":{"given_name":"Koichi","family_name":"ITO","orcid":null,"role_start":null,"affiliation":{"name":"The University of Tokyo","country":"Japan","ids":[{"id":"https://nrid.nii.ac.jp/nrid/1000010262073","type":"nrid","asserted_by":"kaken"}]},"author":{"id":"https://openalex.org/A5028206707","display_name":"Koichi Ito","orcid":"https://orcid.org/0000-0002-2042-405X"},"institutions":[{"id":"https://openalex.org/I74801974","display_name":"The University of Tokyo","ror":"https://ror.org/057zh3y96","country_code":"JP","type":"education","lineage":["https://openalex.org/I74801974"]}]},"co_lead_investigator":null,"investigators":null,"works_api_url":"https://api.openalex.org/works?filter=awards.id:G1967463549","primary_topic":{"id":"https://openalex.org/T10521","display_name":"RNA and protein synthesis mechanisms","score":0.9816,"subfield":{"id":"https://openalex.org/subfields/1312","display_name":"Molecular Biology"},"field":{"id":"https://openalex.org/fields/13","display_name":"Biochemistry, Genetics and Molecular Biology"},"domain":{"id":"https://openalex.org/domains/1","display_name":"Life Sciences"}},"topics":[{"id":"https://openalex.org/T10521","display_name":"RNA and protein synthesis mechanisms","score":0.9816,"subfield":{"id":"https://openalex.org/subfields/1312","display_name":"Molecular Biology"},"field":{"id":"https://openalex.org/fields/13","display_name":"Biochemistry, Genetics and Molecular Biology"},"domain":{"id":"https://openalex.org/domains/1","display_name":"Life Sciences"}}],"institution_awarded":[{"id":"https://openalex.org/I74801974","display_name":"The University of Tokyo","ror":"https://ror.org/057zh3y96","country_code":"JP","type":"education","lineage":["https://openalex.org/I74801974"]}],"updated_date":"2026-11-11T03:01:08.000Z","created_date":"2026-07-13T04:17:19.000Z"}
