The intricacies of eIF2β-γ interaction in promoting Met-tRNAiMet binding are not clearly understood. Previously, the zinc-binding domain (ZBD) eIF2βS264Y mutation was reported to cause Met-tRNAiMet binding defect due to the intrinsic GTPase activity. We showed that the eIF2βS264Y mutation has eIF2β-γ interaction defect. Consistently, the eIF2βT238A intragenic suppressor mutation restored the eIF2β-γ and Met-tRNAiMet binding. The eIF2β-ZBD residues Asn252Asp and Arg253Ala mutation caused Met-tRNAiMet binding defect that was partially rescued by the eIF2βT238A mutation, suggesting the eIF2β-ZBD modulates Met-tRNAiMet binding. The suppressor mutation rescued the translation initiation fidelity defect of the eIF2γN135D SW-I mutation and eIF2βF217A/Q221A double mutation in the HTH domain. The eIF2βT238A suppressor mutation could not rescue the eIF2β binding defect of the eIF2γV281K mutation; however, combining the eIF2βS264Y mutation with the eIF2γV281K mutation was lethal. In addition to the previously known interaction of eIF2β with the eIF2γ subunit via its α1-helix, the eIF2β-ZBD also interacts with the eIF2γ subunit via guanine nucleotide-binding interface; thus, the eIF2β-γ interacts via two distinct binding sites.</p>","PeriodicalId":8926,"journal":{"name":"Bioscience Reports","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11230868/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141316696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An apo(a)-size independent assay assessed plasma Lp(a) concentrations; all other lipid and apolipoprotein concentrations were measured using standard laboratory techniques. Quantitative real-time polymerase chain reaction was used to determine apo(a) isoforms. The range of metabolic (HbA1c, blood pressure, and blood lipids) and blood lipid variables were similar between the non-carriers and carriers in age, ethnicity and BMI adjusted models.
