A novel mechanism of RNase L inhibition: Theiler\u27s virus L* protein prevents 2-5A from binding to RNase L [PDF]
, 2018 The OAS/RNase L pathway is one of the best-characterized effector pathways of the IFN antiviral response. It inhibits the replication of many viruses and ultimately promotes apoptosis of infected cells, contributing to the control of virus spread ...

Inhibition of Murine Cytomegalovirus Infection in Animals by RNase P-Associated External Guide Sequences. [PDF]
, 2017 External guide sequence (EGS) RNAs are associated with ribonuclease P (RNase P), a tRNA processing enzyme, and represent promising agents for gene-targeting applications as they can direct RNase-P-mediated cleavage of a target mRNA.

RNase P Branches Out from RNP to Protein: Organelle-Triggered Diversification? [PDF]
, 2012 RNase P is the enzyme that removes 5′ leader sequences from precursor tRNAs. Remarkably, in most organisms, RNase P is a ribonucleoprotein particle where the RNA component is responsible for catalysis. In this issue of Genes \u26 Development, Gutmann and

Protein synthesis inhibitors and catalytic RNA Effect of puromycin on tRNA precursor processing by the RNA component of Escherichia coli RNase P [PDF]
, 1989 RNase P and ribosomes must interact with similar substrate molecules, tRNA precursors in the case of RNase P and aminoacyl-, peptidyl- or free tRNAs in the case of ribosomes.

Influence of Conformation of M. tuberculosis RNase P Protein Subunit on Its Function. [PDF]
PLoS ONE, 2016 RNase P is an essential enzyme that processes 5' end leader sequence of pre-tRNA to generate mature tRNA. The bacterial RNase Ps contain a RNA subunit and one protein subunit, where the RNA subunit contains the catalytic activity.

Architecture and Function of the Human Endonucleases RNase P and RNase MRP [PDF]
IUBMB Life, 2000 AbstractIn the past decade, important advances have been made in our knowledge of the composition of human RNase MRP and RNase P complexes. Both ribonucleoprotein particles function as endonucleases and contain RNA components that are structurally related.

Insights into the structure and activity of prototype foamy virus RNase H
Retrovirology, 2012 Background RNase H is an endonuclease that hydrolyzes the RNA strand in RNA/DNA hybrids. Retroviral reverse transcriptases harbor a C-terminal RNase H domain whose activity is essential for viral replication.

Cryo-EM structure of catalytic ribonucleoprotein complex RNase MRP
Nature Communications, 2020 Ribozyme-based RNase MRP is an essential eukaryotic enzyme involved in the maturation of rRNA and is evolutionarily related to RNase P. Here, the authors present the 3.0 Å cryo-EM structure of the S.
