The development of convenient methods for controlling the protein expression is an important challenge in the postgenomic era. We applied the crosslink forming oligonucleotide (CFO) as a terminator of the ribosomal translation. In this study, we demonstrated that the improved reactivity of our CFO under physiological conditions enabled the sequence-specific introduction of a steric block for a ribosome on mRNAs. In vitro and in cell translation experiments revealed that the crosslinked mRNA can produce the truncated proteins in which the translation terminates at the desired position.
