A streamlined protocol for the detection of mRNA–sRNA interactions using AMT-crosslinking in vitro

open access: yesBioTechniques, 2019
Until recently, RNA–RNA interactions were mainly identified by crosslinking RNAs with interacting proteins, RNA proximity ligation and deep sequencing. Recently, AMT-based direct RNA crosslinking was established.

Identification of novel components of Trypanosoma brucei editosomes [PDF]

open access: yes, 2003
The editosome is a multiprotein complex that catalyzes the insertion and deletion of uridylates that occurs during RNA editing in trypanosomatids. We report the identification of nine novel editosome proteins in Trypanosoma brucei.

Tumor suppressor mediated ubiquitylation of hnRNPK is a barrier to oncogenic translation

open access: yesNature Communications, 2022
Cytoplasmic accumulation of RNA binding protein, hnRNPK in cancer cells is associated with poor prognosis. Here the authors show that SCFFbxo4 E3 ubiquitin ligase-mediated polyubiquitylation of hnRNPK restricts c-Myc translation and limits cancer ...

Isolation of novel ribozymes that ligate AMP-activated RNA substrates [PDF]

open access: yes, 1997
Background: The protein enzymes RNA ligase and DNA ligase catalyze the ligation of nucleic acids via an adenosine-5′-5′-pyrophosphate ‘capped’ RNA or DNA intermediate. The activation of nucleic acid substrates by adenosine 5′-monophosphate (AMP) may be a

Scaling properties of RNA as a randomly branching polymer [PDF]

open access: yesJ. Chem. Phys. 158, 234901 (2023), 2023
Formation of base pairs between the nucleotides of an RNA sequence gives rise to a complex and often highly branched RNA structure. While numerous studies have demonstrated the functional importance of the high degree of RNA branching -- for instance, for its spatial compactness or interaction with other biological macromolecules -- RNA branching ...

An improved protocol for small RNA library construction using High Definition adapters [PDF]

open access: yes, 2015
Next generation sequencing of small RNA (sRNA) libraries is widely used for studying sRNAs in various biological systems. However, cDNA libraries of sRNAs are biased for molecules that are ligated to adapters more or less efficiently than other molecules.

Ribonucleolytic resection is required for repair of strand displaced nonhomologous end-joining intermediates [PDF]

open access: yes, 2013
Nonhomologous end-joining (NHEJ) pathways repair DNA double-strand breaks (DSBs) in eukaryotes and many prokaryotes, although it is not reported to operate in the third domain of life, archaea. Here, we describe a complete NHEJ complex, consisting of DNA

Structural and mutational analysis of archaeal ATP-dependent RNA ligase identifies amino acids required for RNA binding and catalysis

open access: yesNucleic Acids Research, 2016
An ATP-dependent RNA ligase from Methanobacterium thermoautotrophicum (MthRnl) catalyzes intramolecular ligation of single-stranded RNA to form a closed circular RNA via covalent ligase-AMP and RNA-adenylylate intermediate.

Reconciling Ligase Ribozyme Activity with Fatty Acid Vesicle Stability

open access: yesLife, 2014
The “RNA world” and the “Lipid world” theories for the origin of cellular life are often considered incompatible due to the differences in the environmental conditions at which they can emerge.

The subnuclear localization of tRNA ligase in yeast [PDF]

open access: yes, 1987
Yeast tRNA ligase is an enzyme required for tRNA splicing. A study by indirect immune fluorescence shows that this enzyme is localized in the cell nucleus. At higher resolution, studies using indirect immune electron microscopy show this nuclear location
