Composition and conservation of the mRNA-degrading machinery in bacteria [PDF]

open access: yes, 2011
RNA synthesis and decay counteract each other and therefore inversely regulate gene expression in pro- and eukaryotic cells by controlling the steady-state level of individual transcripts.

Defining substrate specificities of human RNA capping methyltransferases through quantitative assessment of independent yet cooperative activities

open access: yesProtein Science, Volume 35, Issue 1, January 2026.
Abstract Human RNA capping is critical for mRNA splicing, protection of RNA from 5′ exonucleases in the cytoplasm, and targeting to the ribosome. Human RNMT, CMTR1, and CMTR2 are RNA methyltransferases involved in the RNA capping process. They play a significant role in the proliferation and differentiation of embryonic stem cells and have been ...

A DIStinctively novel exoribonuclease that really likes U

open access: yesThe EMBO Journal, 2013
Regulated degradation plays a major role in determining the levels of both non-coding (miRNA) and coding (mRNA) transcripts. Thus, insights into the factors and pathways that influence this process have broad, interdisciplinary implications. New findings by Malecki et al (2013), Lubas et al (2013), and Chang et al (2013) identify the protein Dis3L2 as ...

Neuronal XRN1 is required for maintenance of whole-body metabolic homeostasis

open access: yesiScience, 2021
Summary: Control of mRNA stability and degradation is essential for appropriate gene expression, and its dysregulation causes various disorders, including cancer, neurodegenerative diseases, diabetes, and obesity.

Structure Modeling Protocols for Protein Multimer and RNA in CASP16 With Enhanced MSAs, Model Ranking, and Deep Learning

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 1, Page 167-182, January 2026.
ABSTRACT We present the methods and results of our protein complex and RNA structure predictions at CASP16. Our approach integrated multiple state‐of‐the‐art deep learning models with a consensus‐based scoring method. To enhance the depth of multiple sequence alignments (MSAs), we employed a large metagenomic sequence database.

Functional Relevance of CASP16 Nucleic Acid Predictions as Evaluated by Structure Providers

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 1, Page 51-78, January 2026.
ABSTRACT Accurate biomolecular structure prediction enables the prediction of mutational effects, the speculation of function based on predicted structural homology, the analysis of ligand binding modes, experimental model building, and many other applications.

RNA Degradation Assay Using RNA Exosome Complexes, Affinity-purified from HEK-293 Cells

open access: yesBio-Protocol, 2017
The RNA exosome complex plays a central role in RNA processing and regulated turnover. Present both in cytoplasm and nucleus, the exosome functions through associations with ribonucleases and various adapter proteins (reviewed in [Kilchert et al., 2016]).

Elucidation of the Photorhabdus temperata Genome and Generation of a Transposon Mutant Library To Identify Motility Mutants Altered in Pathogenesis [PDF]

open access: yes, 2015
The entomopathogenic nematode Heterorhabditis bacteriophora forms a specific mutualistic association with its bacterial partner Photorhabdus temperata.

The Arabidopsis deNADding Enzyme DXO1 Modulates the Plant Immunity Response

open access: yesPlant, Cell &Environment, Volume 49, Issue 1, Page 32-50, January 2026.
ABSTRACT DXO1, the only DXO homolog in Arabidopsis, due to its plant‐specific features, exhibits strong deNADding enzymatic activity but has no apparent role in 5′ QC. Despite its important contribution to plant RNA metabolism, the direct impact of DXO1 enzymatic activity on cellular processes appears surprisingly limited.

ISG20L2, a Novel Vertebrate Nucleolar Exoribonuclease Involved in Ribosome Biogenesis [PDF]

open access: yesMolecular & Cellular Proteomics, 2008
Proteomics analyses of human nucleoli provided molecular bases for an understanding of the multiple functions fulfilled by these nuclear domains. However, the biological roles of about 100 of the identified proteins are unpredictable. The present study describes the functional characterization of one of these proteins, ISG20L2.
