During genetic information transfer from DNA to protein, gene expression is strictly controlled at several key stages. Post-transcriptional regulation provides a plethora of mechanisms for precise and rapid control of gene expression, ensuring cellular survival and environmental adaptation. Emerging evidence shows that Archaea, the third domain of life, employ diverse post-transcriptional regulation strategies, including distinct RNA-associated proteins and small noncoding RNAs (sRNAs), to control gene expression. 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.

What is Gene Expression?
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
