RNA-binding properties and RNA chaperone activity of human peroxiredoxin 1
Biochemical and Biophysical Research Communications, 2012Human peroxiredoxin 1 (hPrx1), a member of the peroxiredoxin family, detoxifies peroxide substrates and has been implicated in numerous biological processes, including cell growth, proliferation, differentiation, apoptosis, and redox signaling. To date, Prx1 has not been implicated in RNA metabolism.

Disordered RNA chaperone proteins: from functions to disease
Cellular and Molecular Life Sciences, 2005RNA chaperones are ubiquitous proteins that play pivotal roles in cellular RNA metabolism and RNA virus replication. Here we propose that they act by organizing complex and highly dynamic networks of RNA-RNA, RNA-protein and protein-protein interactions.

Assays for the RNA chaperone activity of proteins
Biochemical Society Transactions, 2005Proteins with RNA chaperone activity promote RNA folding by loosening the structure of misfolded RNAs or by preventing their formation. How these proteins achieve this activity is still unknown, the mechanism is not understood and it is unclear whether this activity is always based on the same mechanism or whether different RNA chaperones use different

aDEAD-end job for RNA chaperone
Trends in Biochemical Sciences, 2002Protein chaperones bind non-native polypeptides and rescue kinetic traps in protein folding pathways. One of their key characteristics is specificity for non-native states rather than particular polypeptide sequences. Similarly, RNA chaperones have been invoked to solve problems during RNA folding, for example by binding to non-native secondary and ...

RNA structural remodeling by RNA annealer proteins and RNA chaperones
2011As with all biological macromolecules, RNA molecules need to adopt distinct three-dimensional structures in order to complete their tasks inside the cell. Nevertheless, structural flexibility is a necessity for many RNAs that exist in more than one functional conformation and that need to adapt to environmental stimuli.
