Deciphering the RNA capping process in bacteria [PDF]

open access: yesProceedings of the National Academy of Sciences, 2020
RNA capping in eukaryotes has been studied since the 1970s, starting with the discovery of 5′ 7-methylguanylate caps in the Shatkin laboratory (1). That capping mechanism involves a pause during transcription elongation that allows the recruitment of specialized capping enzymes to modify the 5′ end of the nascent RNA.

Disparate Roles of Oxidative Stress in Rostral Ventrolateral Medulla in Age-Dependent Susceptibility to Hypertension Induced by Systemic l-NAME Treatment in Rats

open access: yesBiomedicines, 2022
This study aims to investigate whether tissue oxidative stress in the rostral ventrolateral medulla (RVLM), where sympathetic premotor neurons reside, plays an active role in age-dependent susceptibility to hypertension in response to nitric oxide (NO ...

The expanding field of non-canonical RNA capping: new enzymes and mechanisms

open access: yesRoyal Society Open Science, 2021
Recent years witnessed the discovery of ubiquitous and diverse 5′-end RNA cap-like modifications in prokaryotes as well as in eukaryotes. These non-canonical caps include metabolic cofactors, such as NAD+/NADH, FAD, cell wall precursors UDP-GlcNAc ...

Preparation of RNAs with non-canonical 5′ ends using novel di- and trinucleotide reagents for co-transcriptional capping

open access: yesFrontiers in Molecular Biosciences, 2022
Many eukaryotic and some bacterial RNAs are modified at the 5′ end by the addition of cap structures. In addition to the classic 7-methylguanosine 5′ cap in eukaryotic mRNA, several non-canonical caps have recently been identified, including NAD-linked ...

CapZyme-Seq: A 5′-RNA-Seq Method for Differential Detection and Quantitation of NAD-Capped and Uncapped 5′-Triphosphate RNA

open access: yesSTAR Protocols, 2020
Summary: Nucleoside-containing metabolites such as the oxidized and reduced forms of nicotinamide adenine dinucleotide (NAD+ and NADH), 3′-desphospho-coenzyme A (dpCoA), and flavin adenine dinucleotide (FAD) can be incorporated as RNA 5′ end caps by ...

Biological roles of DExH RNA helicase, RHAU [PDF]

open access: yes, 2007
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.

The effect of ppGpp and DksA on NAD+ capped RNA species

open access: yes, 2023
Bird, Jeremy. G.5´ end ribonucleic acid caps play an important role in both regulation of gene expression and half-life of RNAs. Canonically, eukaryotes utilize the evolutionarily conserved methyl-7-guanosine (m7G) cap for mRNA nuclear export and to ...

Potential Drugs Targeting Early Innate Immune Evasion of SARS-Coronavirus 2 via 2’-O-Methylation of Viral RNA

open access: yesViruses, 2020
The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causing the COVID-19 respiratory disease pandemic utilizes unique 2′-O-methyltransferase (2′-O-MTase) capping machinery to camouflage its RNA from innate immune recognition.
