Comments

FUNCTION: Essential for viral replication. Plays an important role during transcription of early mRNAs, presumably by preventing R-loop formation behind the elongating RNA polymerase. Acts as NTP-dependent helicase that catalyzes unidirectional unwinding of 3'tailed duplex RNAs. Might also play a role in the export of newly synthesized mRNA chains out of the core into the cytoplasm. Required for propagation of viral particles.
CATALYTIC ACTIVITY: NTP + H₂O = NDP + phosphate.
SIMILARITY: Belongs to the DEAD box helicase family. DEAH subfamily.
SIMILARITY: Contains 1 helicase ATP-binding domain.
SIMILARITY: Contains 1 helicase C-terminal domain.
