RNA Chaperones, RNA Annealers and RNA Helicases [PDF]
RNA molecules face difficulties when folding into their native structures. In the cell, proteins can assist RNAs in reaching their functionally active states by binding and stabilizing a specific structure or, in a quite opposite way, by interacting in a non-specific manner. These proteins can either facilitate RNA-RNA interactions in a reaction termed

RNA remodeling by hexameric RNA helicases [PDF]
The unwinding of RNA helices and the disruption of RNA-protein complexes are critical steps of cellular metabolism that are carried out by ubiquitous NTP-dependent enzymes named RNA helicases. Here, we review the structures, mechanisms, and biochemical properties of two RNA helicases known to adopt a homo-hexameric ring architecture: the P4 packaging ...

HrpA, an RNA helicase involved in RNA processing, is required for mouse infectivity and tick transmission of the Lyme disease spirochete. [PDF]
The Lyme disease spirochete Borrelia burgdorferi must differentially express genes and proteins in order to survive in and transit between its tick vector and vertebrate reservoir. The putative DEAH-box RNA helicase, HrpA, has been recently identified as

Role and therapeutic potential of DEAD-box RNA helicase family in colorectal cancer
Colorectal cancer (CRC) is the third most commonly diagnosed and the second cancer-related death worldwide, leading to more than 0.9 million deaths every year. Unfortunately, this disease is changing rapidly to a younger age, and in a more advanced stage

Domain orientation in the RNA helicase YxiN and the role of conformational changes for RNA unwinding [PDF]
The RNA helicase YxiN from Bacillus subtilis is a member of the family of DEAD box proteins. YxiN is able to unwind RNA double strands in an ATP-dependent manner. The ability to catalyse RNA rearrangement is in vivo presumably necessary for the bacterial

Biological roles of DExH RNA helicase, RHAU [PDF]
In this thesis, I have described the work carried out on a single protein called RHAU, dealing with aspects of protein localization in cells, the regulation of global gene expression by different mechanisms, and cellular stress-responses.

Helicase: A genetic tool for providing stress tolerance in plants
Alteration of stress (abiotic and biotic) constitutes one of the major problems for normal plants health. In the present scenario, new molecular tools are broadly utilized to improve stress tolerance and high-yielding crop plants.
