Since mRNAs play a key role in protein synthesis in vivo, the use of mRNAs as medicines and for in vitro protein synthesis has been desired. In particular, mRNA therapeutics hold the potential for application to vaccine therapy against coronaviruses and are being developed. However, the efficiency of protein production with mRNAs in the natural form is not sufficient enough for certain purposes, including application to mRNA therapeutics. Therefore, mRNA molecules allowing for efficient protein production have been required to be developed.
