Chaperna: linking the ancient RNA and protein worlds

open access: yesRNA Biology, 2021
As a mental framework for the transition of self-replicating biological forms, the RNA world concept stipulates a dual function of RNAs as genetic substance and catalyst.

Single-molecule stretching studies of RNA chaperones [PDF]

open access: yesRNA Biology, 2010
RNA chaperone proteins play significant roles in diverse biological contexts. The most widely studied RNA chaperones are the retroviral nucleocapsid proteins (NC), also referred to as nucleic acid (NA) chaperones. Surprisingly, the biophysical properties of the NC proteins vary significantly for different viruses, and it appears that HIV-1 NC has ...

Sigma-1 receptor chaperones rescue nucleocytoplasmic transport deficit seen in cellular and Drosophila ALS/FTD models

open access: yesNature Communications, 2020
The (G4C2)-RNA hexanucleotide repeat expansion upstream of the start codon of the C9orf72 gene plays a critical role in familial ALS. The authors show that Sig1R, a ligand-regulated molecular chaperone, counteracts the aberrant nucleocytoplasmic ...

Subinhibitory concentrations of trimethoprim and sulfamethoxazole prevent biofilm formation by Acinetobacter baumannii through inhibition of Csu pilus expression [PDF]

open access: yes, 2017
Acinetobacter baumannii is emerging as a multidrug-resistant nosocomial pathogen of increasing threat to human health worldwide. Pili are important bacterial virulence factors, playing a role in attachment to host cells and biofilm formation.

Selective recruitment of stress-responsive mRNAs to ribosomes for translation by acetylated protein S1 during nutrient stress in Escherichia coli

open access: yesCommunications Biology, 2022
RNA molecular chaperone S1 is acetylated and selectively recruits stress-responsive mRNAs to the ribosome during nitrogen starvation in E. coli, revealing a translation regulation mechanism for nutrient stress adaptation.

RNA Helicase Proteins as Chaperones and Remodelers [PDF]

open access: yesAnnual Review of Biochemistry, 2014
Superfamily 2 helicase proteins are ubiquitous in RNA biology and have an extraordinarily broad set of functional roles. Central among these roles are the promotion of rearrangements of structured RNAs and the remodeling of ribonucleoprotein complexes (RNPs), allowing formation of native RNA structure or progression through a functional cycle of ...

Advances in chaperone-assisted RNA crystallography using synthetic antibodies

open access: yesBBA Advances, 2023
RNA molecules play essential roles in many biological functions, from gene expression regulation, cellular growth, and metabolism to catalysis. They frequently fold into three-dimensional structures to perform their functions.

Regulation of CLC-1 chloride channel biosynthesis by FKBP8 and Hsp90β. [PDF]

open access: yes, 2016
Mutations in human CLC-1 chloride channel are associated with the skeletal muscle disorder myotonia congenita. The disease-causing mutant A531V manifests enhanced proteasomal degradation of CLC-1.

A Novel Therapeutic Strategy for the Treatment of Glioma, Combining Chemical and Molecular Targeting of Hsp90a [PDF]

open access: yes, 2011
Hsp90α's vital role in tumour survival and progression, together with its highly inducible expression profile in gliomas and its absence in normal tissue and cell lines validates it as a therapeutic target for glioma.

Diversity of bacterial small RNAs drives competitive strategies for a mutual chaperone

open access: yesNature Communications, 2022
Bacterial sRNAs compete for limited copies of an RNA chaperone. Here, real-time single-molecule imaging shows that pairwise interactions of sRNAs with Hfq determine if the sRNAs are actively exchanged or stably coexist on the shared protein.
