Key result
The translational enhancer domain (TED) of satellite tobacco necrosis virus stimulates translation of uncapped heterologous mRNAs in vitro by increasing translation efficiency to the level of capped mRNA.
Population
In vitro wheat germ translation system using synthetic transcripts (STNV RNA, cat mRNAs)
Comparison
Translational enhancer domain from satellite… vs mRNAs lacking TED or lacking a 5' cap
Design
Preclinical

I
Intervention
Translational enhancer domain (TED) from satellite tobacco necrosis virus (STNV) RNA
C
Comparator
mRNAs lacking TED or lacking a 5' cap
O
Outcome
Translation efficiency and functional half-life of mRNAsurrogate
The STNV translational enhancer domain (TED) autonomously stimulates cap-independent translation by recruiting translational machinery, functioning independently of its position within the mRNA.

Meulewaeter et al. (1998) studied this question. Translational enhancer domain (TED) vs. RNA lacking TED was evaluated on Translation efficiency. The translational enhancer domain (TED) of satellite tobacco necrosis virus stimulates translation of uncapped heterologous mRNAs in vitro by increasing translation efficiency to the level of capped mRNA.
