Discusses a study which reveals that the eukaryotic ribosomal protein L30 binds to the selenocysteine recoding RNA element and may function to tether the recoding machinery to the translating ribosome. Process demonstrating that eukarya recruit a ribosomal protein, L30, to selenoprotein mRNAs, presumably to assist in recoding at the ribosome; Key features of the recoding process by which UGA is read as selenocysteine in bacteria.
