First identified 20 years ago as an RNA polymerase II-associated putative histone acetyltransferase, the conserved Elongator complex has since been recognized as the central player of a complex, regulated, and biologically relevant epitranscriptomic pathway targeting the wobble uridine of some tRNAs. Numerous studies have contributed to three emerging concepts resulting from anticodon modification by Elongator: the codon-specific control of translation, the ability of reprogramming translation in various physiological or pathological contexts, and the maintenance of proteome integrity by counteracting protein aggregation. These three aspects of tRNA modification by Elongator constitute a new layer of regulation that fundamentally contributes to gene expression and are now recognized as being critically involved in various human diseases.
