Abstract excerpt

tmRNA has a dual function as a tRNA and an mRNA to facilitate trans-translation, in which a ribosome can switch between translation of a truncated mRNA and the tmRNA's tag sequence. SmpB is a tmRNA binding protein that has been identified to be essential for trans-translation in vivo. To further...
