Abstract

In protein-RNA complexes, UVC crosslinks proteins predominantly to uracil. Concrete evidence for other UVC-crosslinked RNA bases is lacking. Here, I elucidate mass spectrometric signatures of UVC-crosslinked guanine, cytidine, and methyladenine. This can help us capture the native protein-RNA interactions in more detail.
