Research Abstract |
Trans-translation is an irregular translation system, in which tmRNA (transfer and messenger RNA) rescues the ribosome stalled at the 3' end of truncated mRNA lacking a termination codon to produce a chimeric polypeptide from two messages on truncated mRNA and tmRNA. It provides an incomplete nascent polypeptide from a truncated mRNA with a tag for degradation to promote degradation of truncated mRNA. This project revealed the molecular mechanism of the early stage of trans-translation based on our proposal that SmpB, a tmRNA binding protein, mimics both tRNA and mRNA.
