Installation of tRNA modifications is key to protein synthesis.

In her presentation at #Biochemistry2026, Carine Tisné presented her group's in depth work on structural and functional studies to understand the underlying processes on the example of m1A.

Everything needed to make #DNA and #RNA found in #asteroid sample
Results from #Ryugu suggest the Solar System produced the building blocks of life
As outlined in a paper titled “A complete set of canonical nucleobases in the carbonaceous asteroid (162173) Ryugu” that appeared in the journal Nature #Astronomy this week, analysis of samples from Ryugu turned up “all five canonical nucleobases – purines (adenine and guanine) and pyrimidines (cytosine, thymine and uracil).”

How can we study the function of nucleotide-based #SecondMessengers?

Carina Baer de Oliveira Mann presented her group's exciting findings in this field at #Biochemistry2026. She e.g. presented the #cryoEM structure of OAS2, which has key #antiviral functions.
