{"doi":"10.1042/bst20140063","title":"eIF4E-binding proteins: new factors, new locations, new roles","abstract":"<jats:p>The cap-binding translation initiation factor eIF4E (eukaryotic initiation factor 4E) is central to protein synthesis in eukaryotes. As an integral component of eIF4F, a complex also containing the large bridging factor eIF4G and eIF4A RNA helicase, eIF4E enables the recruitment of the small ribosomal subunit to the 5′ end of mRNAs. The interaction between eIF4E and eIF4G via a YXXXXLϕ motif is regulated by small eIF4E-binding proteins, 4E-BPs, which use the same sequence to competitively bind eIF4E thereby inhibiting cap-dependent translation. Additional eIF4E-binding proteins have been identified in the last 10–15 years, characterized by the YXXXXLϕ motif, and by interactions (many of which remain to be detailed) with RNA-binding proteins, or other factors in complexes that recognize the specific mRNAs. In the present article, we focus on the metazoan 4E-T (4E-transporter)/Cup family of eIF4E-binding proteins, and also discuss very recent examples in yeast, fruitflies and humans, some of which predictably inhibit translation, while others may result in mRNA decay or even enhance translation; altogether considerably expanding our understanding of the roles of eIF4E-binding proteins in gene expression regulation.</jats:p>","journal":"Biochemical Society Transactions","year":2014,"id":21175,"datarank":1.4255285029068658,"base_score":3.58351893845611,"endowment":3.58351893845611,"self_citation_contribution":0.5375278407684165,"citation_network_contribution":0.8880006621384494,"self_endowment_contribution":0.5375278407684165,"citer_contribution":0.8880006621384494,"corpus_percentile":null,"corpus_rank":null,"citation_count":35,"citer_count":30,"citers_with_citation_signal":27,"citers_with_endowment":27,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":137342,"name":"Clare Simpson","orcid":null,"position":1,"is_corresponding":false},{"id":137343,"name":"Nancy Standart","orcid":null,"position":2,"is_corresponding":false},{"id":137341,"name":"Anastasiia Kamenska","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":3.58351893845611,"endowment":3.58351893845611,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"25110031","pmcid":null,"openalex_id":"https://openalex.org/W2054339897","authors":[],"funders":[{"funder_name":"Biotechnology and Biological Sciences Research Council","grant_id":"BB/J00779X/1","title":null},{"funder_name":"Wellcome Trust","grant_id":"","title":null},{"funder_name":"Biotechnology and Biological Sciences Research Council","grant_id":"","title":null},{"funder_name":"Wellcome Trust","grant_id":"","title":null},{"funder_name":"Biotechnology and Biological Sciences Research Council","grant_id":"","title":null}],"total_grants":5,"fwci":1.4226,"citation_percentile":0.80949965,"influential_citations":3,"citation_trend":[{"year":2014,"count":1},{"year":2015,"count":2},{"year":2016,"count":5},{"year":2017,"count":2},{"year":2018,"count":6},{"year":2019,"count":3},{"year":2020,"count":4},{"year":2021,"count":3},{"year":2022,"count":1},{"year":2023,"count":4},{"year":2024,"count":3},{"year":2025,"count":1}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://portlandpress.com/biochemsoctrans/article-pdf/42/4/1238/436015/bst0421238.pdf","host_type":"publisher"},{"url":"https://doi.org/10.1042/bst20140063","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/25110031","host_type":"repository"}],"fields_of_study":["PI3K/AKT/mTOR signaling in cancer","Protein Kinase Regulation and GTPase Signaling","Polyamine Metabolism and Applications","Biology","Medicine","Animals","Eukaryotic Initiation Factor-4E","Humans","RNA Stability","RNA-Binding Proteins"],"mesh_terms":["Animals","Humans","RNA-Binding Proteins","RNA Stability","Eukaryotic Initiation Factor-4E"],"keywords":["EIF4G","EIF4E","Initiation factor","Eukaryotic translation","eIF4A","EIF4A1","Biology","EIF4EBP1","Eukaryotic initiation factor","RNA-binding protein","Cell biology","Eukaryotic translation initiation factor 4 gamma","Protein subunit","Translation (biology)","Genetics","Computational biology","RNA","Messenger RNA","Gene"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-06T14:51:46.243676Z","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":[]}
