Protein purification, crystallization, and structure determination of human DEAD-box RNA helicase DDX21 in different unwinding states
Summary: RNA helicase DDX21 plays vital roles in ribosomal RNA processing and the regulation of host innate immunity during virus infection. Here, we describe the optimized protocols for nucleic acid-free protein purification and crystallization of DDX21 in its different unwinding states. Rational d...
