translation of mrna.

摘要

It has been found that the 5' regions of RNA viruses act as enhancers of translation of mRNA. The omega prime ( OMEGA ') sequence of Tobacco Mosaic Virus, derivatives and portions thereof, and 5' leader sequences of other RNA viruses can be ligated upstream of an appropriate mRNA or used in the form of cDNA in an expression vector. The translational enhancers are effective in many different types of expression system, for example plant cells, bacteria, and animal cells, and also in in vitro translation.
