Post-transcriptional regulation provides a plethora of mechanisms for precise and rapid control of gene expression, ensuring cellular survival and environmental adaptation.

This review summarizes recent advances in understanding archaeal post-transcriptional regulation, focusing on processes, mechanisms, and physiological significances, and key elements including sRNAs, 5'- or 3'-untranslated regions (5'-UTRs or 3'-UTRs), RNA-binding proteins (RBPs) or chaperones, and ribonucleases, underscoring their crucial roles in optimizing archaeal gene expression for survival and environmental responsiveness.</p>","PeriodicalId":23275,"journal":{"name":"Trends in Microbiology","volume":" ","pages":"765-781"},"PeriodicalIF":14.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143574130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We highlight the versatile role of aerobic methane-oxidizing bacteria in electrochemically driven methane oxidation, and the non-syntrophic lifestyle of anaerobic methanotrophic archaea (ANME) enabled by their extracellular electron transfer (EET) pathways. These aspects are followed by a review of recent findings on the potential reversibility of methanogen metabolism, with a focus on the proposed EET pathways that may facilitate their shift to a methane-oxidizing phenotype, a topic that remains under active investigation and debate.
