Guanine quadruplexes (G4s) are an important structure of nucleic acids (DNA and RNA) with roles in several cellular processes. RNA G4s require specialized unwinding enzymes, of which only two have been previously identified. We describe the results of a simple and specific mass spectrometry guided method used to screen HEK293T cell lysate for G4 binding proteins. From these results, we validated the RNA helicase protein DDX21. DDX21 is an established RNA helicase, but has not yet been validated ...[more]
