The DEAD box RNA helicase family in Arabidopsis thaliana [PDF]
The numerous genomic sequences and ESTs released by the Arabidopsis thaliana Genome Initiative (AGI) have allowed a systematic and functional study of the DEAD box RNA helicase family. Sequencing and in silico analysis led to the characterization of 28 novel A. thaliana DEAD box RNA helicases forming a family of 32 members, named AtRH.

Coordinated function of cellular DEAD-box helicases in suppression of viral RNA recombination and maintenance of viral genome integrity. [PDF]
The intricate interactions between viruses and hosts include an evolutionary arms race and adaptation that is facilitated by the ability of RNA viruses to evolve rapidly due to high frequency mutations and genetic RNA recombination.

RNA Unwinding by the Trf4/Air2/Mtr4 Polyadenylation (TRAMP) Complex [PDF]
Many RNA-processing events in the cell nucleus involve the Trf4/Air2/Mtr4 polyadenylation (TRAMP) complex, which contains the poly(A) polymerase Trf4p, the Zn-knuckle protein Air2p, and the RNA helicase Mtr4p.

Nuclear DDX3 expression predicts poor outcome in colorectal and breast cancer [PDF]
Purpose: DEAD box protein 3 (DDX3) is an RNA helicase with oncogenic properties that shuttles between the cytoplasm and nucleus. The majority of DDX3 is found in the cytoplasm, but a subset of tumors has distinct nuclear DDX3 localization of yet unknown ...

Synthetic lethal interactions of DEAD/H-box helicases as targets for cancer therapy
DEAD/H-box helicases are implicated in virtually every aspect of RNA metabolism, including transcription, pre-mRNA splicing, ribosomes biogenesis, nuclear export, translation initiation, RNA degradation, and mRNA editing.

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 DDX5/Dbp2 subfamily of DEAD‐box RNA helicases [PDF]
The mammalian DEAD‐box RNA helicase DDX5, its paralog DDX17, and their orthologs in Saccharomyces cerevisiae and Drosophila melanogaster, namely Dbp2 and Rm62, define a subfamily of DEAD‐box proteins. Members from this subfamily share highly conserved protein sequences and cellular functions.

Positive-stranded RNA viruses replicate inside cells and depend on many co-opted cellular factors to complete their infection cycles. To combat viruses, the hosts use conserved restriction factors, such as DEAD-box RNA helicases, which can function as ...

Transcriptional profiling of colicin-induced cell death of Escherichia coli MG1655 identifies potential mechanisms by which bacteriocins promote bacterial diversity [PDF]
We report the transcriptional response of Escherichia coli MG1655 to damage induced by colicins E3 and E9, bacteriocins that kill cells through inactivation of the ribosome and degradation of chromosomal DNA, respectively. Colicin E9 strongly induced the
