DEAD-box RNA helicase 21 interacts with the nucleocapsid protein and inhibits porcine deltacoronavirus infection through upregulation of interferon responses
ABSTRACT DEAD-box RNA helicase 21 (DDX21), a conserved RNA helicase of the DEAD-box family, serves as a key regulator of multiple fundamental cellular processes, including RNA metabolism, ribosome biogenesis, transcriptional regulation, and genomic stability. Our previous work has demonstrated an interaction between DD...
