A motif unique to the human DEAD-box protein DDX3 is important for nucleic acid binding, ATP hydrolysis, RNA/DNA unwinding and HIV-1 replication [PDF]
DEAD-box proteins are enzymes endowed with nucleic acid-dependent ATPase, RNA translocase and unwinding activities. The human DEAD-box protein DDX3 has been shown to play important roles in tumor proliferation and viral infections.

The human Suv3 helicase interacts with replication protein A and flap endonuclease 1 in the nucleus [PDF]
The human Suv3 helicase has been shown to be a major player in mitochondrial RNA surveillance and decay. In the present study we identify two new interaction partners of hSUV3: the RPA (replication protein A0 and FEN1 (flap endonuclease).

Roles of the linker region of RNA helicase A in HIV-1 RNA metabolism. [PDF]
RNA helicase A (RHA) promotes multiple steps in HIV-1 production including transcription and translation of viral RNA, annealing of primer tRNA(Lys3) to viral RNA, and elevating the ratio of unspliced to spliced viral RNA.

Molecular characterization of DDX26, a human DEAD-box RNA helicase, located on chromosome 7p12
DEAD-box proteins comprise a family of ATP-dependent RNA helicases involved in several aspects of RNA metabolism. Here we report the characterization of the human DEAD-box RNA helicase DDX26. The gene is composed of 14 exons distributed over an extension

Novel endoribonucleases as central players in various pathways of eukaryotic RNA metabolism [PDF]
For a long time it has been assumed that the decay of RNA in eukaryotes is mainly carried out by exoribonucleases, which is in contrast to bacteria, where endoribonucleases are well documented to initiate RNA degradation.
