Viruses and the human DEAD-box helicase DDX3: inhibition or exploitation?
Human DDX3 is a DEAD (Asp-Glu-Ala-Asp)-box RNA helicase that appears to be a prime target for viral manipulation. While two viruses that manifest major global health threats, HIV and HCV (hepatitis C virus), utilize DDX3 for their replication, other viruses inhibit DDX3's newly identified function in innate antiviral signalling. This review discusses the role of DDX3 in antiviral immunity and i...
متن کاملDEAD-box protein DDX3 associates with eIF4F to promote translation of selected mRNAs.
Here, we have characterized a step in translation initiation of viral and cellular mRNAs that contain RNA secondary structures immediately at the vicinity of their m(7)GTP cap. This is mediated by the DEAD-box helicase DDX3 which can directly bind to the 5' of the target mRNA where it clamps the entry of eIF4F through an eIF4G and Poly A-binding protein cytoplasmic 1 (PABP) double interaction. ...
متن کاملIdentification of the DEAD box RNA helicase DDX3 as a therapeutic target in colorectal cancer
Identifying druggable targets in the Wnt-signaling pathway can optimize colorectal cancer treatment. Recent studies have identified a member of the RNA helicase family DDX3 (DDX3X) as a multilevel activator of Wnt signaling in cells without activating mutations in the Wnt-signaling pathway. In this study, we evaluated whether DDX3 plays a role in the constitutively active Wnt pathway that drive...
متن کاملThe DEAD-box helicase DDX3 supports the assembly of functional 80S ribosomes
The DEAD-box helicase DDX3 has suggested functions in innate immunity, mRNA translocation and translation, and it participates in the propagation of assorted viruses. Exploring initially the role of DDX3 in the life cycle of hepatitis C virus, we observed the protein to be involved in translation directed by different viral internal ribosomal entry sites. Extension of these studies revealed a g...
متن کاملDEAD-box RNA helicase Belle/DDX3 and the RNA interference pathway promote mitotic chromosome segregation.
During mitosis, faithful inheritance of genetic material is achieved by chromosome segregation, as mediated by the condensin I and II complexes. Failed chromosome segregation can result in neoplasm formation, infertility, and birth defects. Recently, the germ-line-specific DEAD-box RNA helicase Vasa was demonstrated to promote mitotic chromosome segregation in Drosophila by facilitating robust ...
