Intersection of small RNA pathways in Arabidopsis thaliana sub-nuclear domains. [PDF]
PLoS ONE, 2013 In Arabidopsis thaliana, functionally diverse small RNA (smRNA) pathways bring about decreased RNA accumulation of target genes via several different mechanisms.

Transcription boundaries of U1 small nuclear RNA. [PDF]
Molecular and Cellular Biology, 1985 Transcription-proximal stages of U1 small nuclear RNA biosynthesis were studied by 32P labeling of nascent chains in isolated HeLa cell nuclei. Labeled RNA was hybridized to nitrocellulose-immobilized, single-stranded M13 DNA clones corresponding to regions within or flanking a human U1 RNA gene. Transcription of U1 RNA was inhibited by greater than 95%

Data on the stability of Prx1-associated snRNAs and mRNAs
Data in Brief, 2019 This data set is related to the research article entitled “Peroxiredoxin 1 post-transcriptionally regulates snoRNA expression” (Kim et al., 2019). It demonstrates that peroxiredoxin 1 (Prx1) increases the stability of Prx1-associated small nuclear RNAs ...

Human GW182 Paralogs Are the Central Organizers for RNA-Mediated Control of Transcription
Cell Reports, 2017 In the cytoplasm, small RNAs can control mammalian translation by regulating the stability of mRNA. In the nucleus, small RNAs can also control transcription and splicing.

Small RNA modifications: regulatory molecules and potential applications
Journal of Hematology & Oncology, 2023 Small RNAs (also referred to as small noncoding RNAs, sncRNA) are defined as polymeric ribonucleic acid molecules that are less than 200 nucleotides in length and serve a variety of essential functions within cells.

Architecture of the U5 small nuclear RNA. [PDF]
Molecular and Cellular Biology, 1994 We have used comparative sequence analysis and deletion analysis to examine the secondary structure of the U5 small nuclear RNA (snRNA), an essential component of the pre-mRNA splicing apparatus. The secondary structure of Saccharomyces cerevisiae U5 snRNA was studied in detail, while sequences from six other fungal species were included in the ...

Dynamic regulation of ARGONAUTE4 within multiple nuclear bodies in Arabidopsis thaliana. [PDF]
PLoS Genetics, 2008 DNA methylation directed by 24-nucleotide small RNAs involves the small RNA-binding protein ARGONAUTE4 (AGO4), and it was previously shown that AGO4 localizes to nucleolus-adjacent Cajal bodies, sites of snRNP complex maturation. Here we demonstrate that

Species Diversity and Molecular Phylogeny of Cyanosporus (Polyporales, Basidiomycota)
Frontiers in Microbiology, 2021 Cyanosporus is a cosmopolitan brown-rot fungal genus, recognizable by blue-tinted basidiocarps. Species in this genus were usually treated as belonging to the Postia caesia complex, however, recent phylogenetic analyses showed that this complex ...

Cloning and molecular characterization of Trypanosoma cruzi U2, U4, U5, and U6 small nuclear RNAs
Memorias do Instituto Oswaldo Cruz, 2007 Small nuclear RNAs (snRNAs) are important factors in the functioning of eukaryotic cells that form several small complexes with proteins; these ribonucleoprotein particles (U snRNPs) have an essential role in the pre-mRNA processing, particularly in ...
