Ddx42p—a human DEAD box protein with RNA chaperone activities
The human gene ddx42 encodes a human DEAD box protein highly homologous to the p68 subfamily of RNA helicases. In HeLa cells, two ddx42 poly(A)+ RNA species were detected both encoding the nuclear localized 938 amino acid Ddx42p polypeptide. Ddx42p has been heterologously expressed and its biochemical properties characterized. It is an RNA binding protein, and ATP and ADP modulate its RNA bindi...
متن کاملDEAD-box RNA helicases in Escherichia coli
In spite of their importance in RNA metabolism, the function of DExD/H-box proteins (including DEAD-box proteins) is poorly understood at the molecular level. Here, we present recent progress achieved with the five DEAD-box proteins from Escherichia coli, which have been particularly well studied. These proteins, which have orthologues in many bacteria, participate, in particular, in specific s...
متن کاملEntropic origin of Mg2+-facilitated RNA folding.
Mg(2+) is essential for the proper folding and function of RNA, though the effect of Mg(2+) concentration on the free energy, enthalpy, and entropy landscapes of RNA folding is unknown. This work exploits temperature-controlled single-molecule FRET methods to address the thermodynamics of RNA folding pathways by probing the intramolecular docking/undocking kinetics of the ubiquitous GAAA tetral...
متن کاملDEAD-box RNA helicases in gram-positive RNA decay.
DEAD-box RNA helicases are important players in eukaryotic and bacterial RNA metabolism. A helicase from Staphylococcus aureus was recently shown to affect RNA decay, most likely via its interaction with the proposed Gram-positive degradosome. Some, but not all, RNAs are stabilized when the helicase CshA is mutated, and among the affected RNAs is the agrBDCA mRNA, which is responsible for quoru...
