The DEAD-box cyanobacterial RNA helicase redox, or CrhR, in Synechocystis sp. PCC 6803 is capable of unwinding dsRNA and in annealing ssRNA in a bidirectional ATP-dependent manner. This is a feature shared by only four other DEAD-box RNA helicases. Two of which, the eukaryotic p68 and p72...

RNA helicases function in all aspects of RNA metabolism, regulating a diverse range of cellular processes by rearranging RNA structures and mediating RNA-protein interactions. Prokaryotic RNA helicases have been shown to have roles in RNA degradation, ribosome biogenesis and translation, with...

West Nile virus (WNV) is a neurotropic, blood-borne flavivirus that can cause serious neurological disease in humans and animals. While significant progress has been made in identifying virus-encoded pathogenic determinants, very little is known regarding how these viral proteins interact with...

The intricate architecture of the eukaryotic cell, which includes the partitioning of the cell into discrete membrane bound organelles, necessitates that various cargos must cross the nuclear envelope (NE). Nuclear pore complexes (NPCs) are large macromolecular assemblies embedded within the NE...

Proteolysis autoregulates expression of the cyanobacterial DEAD-box RNA helicase CrhR, in response to change in growth temperature
DownloadFall 2013
The DEAD box cyanobacterial RNA helicase redox, CrhR, in Synechocystis sp. PCC 6803 is induced in response to environmental stress conditions causing reduction of the redox status of the photosynthetic electron transport chain, with temperature being one of the major conditions commonly...
