#NWOCHAINS2024 comes to an end with an inspiring plenary lecture by Andrea Rentmeister. She talked about her group's exciting work on making RNAs with new functions. Interesting insights into chemoenzymatic benzylation of the cap as well as making translation light-controlled. https://www.nature.com/articles/s41557-022-00972-7
Photocaged 5′ cap analogues for optical control of mRNA translation in cells - Nature Chemistry
Analogues of mRNA 5′ caps containing a photo-cleavable group have now been developed. These so-called FlashCaps can be used for routine in vitro transcription to make long mRNAs containing a cap. In cells, the capped mRNAs are translationally muted; however, upon irradiation by light, the photo-cleavable group is removed without leaving any remaining modification and mRNA is then translated into the corresponding protein.
