Non-canonical RNA caps - cellular reaction to environment and stress

The goal of this project is to understand the role of non-canonical RNA caps (mainly dinucleoside polyphosphates = NpnNs) in prokaryotes and eukaryotes. The 5' termini of the RNA are critical structures and are the least characterized among RNA modifications. In this project, we will develop selective capturing techniques for identification of NpnN-RNA sequences and identify the interacting partners of NpnN-RNA. Furthermore, we will reveal their metabolism and their role in cellular reaction to stress conditions in prokaryotes and eukaryotes. Until recently only canonical structures, NAD or CoA have been known as 5' RNA caps. We discovered an entirely new class of 5' RNA caps - dinucleoside…
