Structures of the NS1 protein and its deletion mutants. The diagram shows the structure of the NS1 protein, including the locations of nuclear localization signals (NLSs) (23), the RNA-binding domain (RBD), the effector domain (ED) (67), and the region that recognizes the eIF4G translation initiation factor (2), as well as the structures of the NS1-81 and NS1-110 deletion mutants.
