Roles of the HEAT repeat proteins Utp10 and Utp20 in 40S ribosome maturation [PDF]
, 2007 A family of HEAT-repeat containing ribosome synthesis factors was previously identified in Saccharomyces cerevisiae. We report the detailed characterization of two of these factors, Utp10 and Utp20, which were initially identified as components of the ...

Diversity of Endonuclease V: From DNA Repair to RNA Editing
Biomolecules, 2015 Deamination of adenine occurs in DNA, RNA, and their precursors via a hydrolytic reaction and a nitrosative reaction. The generated deaminated products are potentially mutagenic because of their structural similarity to natural bases, which in turn leads

Argonaute-dependent small RNAs derived from single-stranded non-structured precursors
Frontiers in Genetics, 2014 A general feature of Argonaute-dependent small RNAs is their base-paired precursor structures, and precursor duplex structures are often required for confident annotation of miRNA genes.

Computational discovery of animal small RNA genes and targets [PDF]
, 2007 Though recently discovered, small RNAs appear to play a wealth of regulatory roles, being involved in degradation of target mRNAs, translation silencing of target genes, chromatin remodeling and transposon silencing.

Detection and Phylogenetic Analysis of Group 1 Coronaviruses in South American Bats
Emerging Infectious Diseases, 2008 Bat coronaviruses (Bt-CoVs) are thought to be the precursors of severe acute respiratory syndrome coronavirus. We detected Bt-CoVs in 2 bat species from Trinidad.

An improved method for surface immobilisation of RNA: application to small Non-Coding RNA - mRNA pairing [PDF]
, 2013 Characterisation of RNA and its intermolecular interactions is increasing in importance as the inventory of known RNA functions continues to expand. RNA-RNA interactions are central to post-transcriptional gene regulation mechanisms in bacteria, and the ...

Export of piRNA precursors by EJC triggers assembly of cytoplasmic Yb-body in Drosophila
Nature Communications, 2016 In Drosophila ovarian follicle cells, piRNAs generated from RNA precursors are processed in cytoplasmic Yb-bodies. The authors identify the exportin and the exon junction complexes as required to transfer precursors to cytoplasm.

Mechanisms of the RNA helicases DDX42 and DDX46 in human U2 snRNP assembly
Nature Communications, 2023 The U2 snRNP recognizes the intron during spliceosome assembly. Here the authors report the high-resolution structures of two assembly precursors of human U2 snRNP and reveal that the RNA helicases DDX42 and DDX46 are mutually exclusive in terms of SF3B1-
