Here we show that the translation of D. melanogaster insulin 2 mRNA ( dilp2 ) is controlled by methylation of N6-adenosine (m 6 A) in the 3’ UTR. Mutations in the m 6 A writer Mettl3 and methylated-residues in the dilp2 3’UTR decreased the levels of dilp2 mRNA associated with the polysomes, and the total amount of dilp2 protein produced. This resulted in aberrant energy homeostasis and diabetic-like phenotypes, consistent with the specific function of dilp2 in adult metabolism. Conserved m 6 A signatures were also identified in the 3’ UTRs of vertebrate insulin mRNAs. These data identify m 6 A as a key regulator of insulin protein synthesis and energy homeostasis in metazoans and demonstrate an essential role for m 6 A in translation, with important implications for diabetes and metabolic disease. One-Sentence Summary The most abundant modification in eukaryotic mRNAs controls the synthesis of insulin protein in D. melanogaster.","journal":"bioRxiv (Cold Spring Harbor Laboratory)","year":2022,"id":311507,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9551,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":14956,"name":"Monica Dus","orcid":"0000-0003-1465-9028","position":1,"is_corresponding":false},{"id":1007701,"name":"Daniel Wilinski","orcid":"0000-0002-6178-8925","position":0,"is_corresponding":true}],"reference_count":39,"raw_metadata":null,"created_at":"2026-07-19T00:33:28.480200Z","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":[]}
