Molecular principles underlying dual RNA specificity in the Drosophila SNF protein [PDF]
, 2018 The first RNA recognition motif of the Drosophila SNF protein is an example of an RNA binding protein with multi-specificity. It binds different RNA hairpin loops in spliceosomal U1 or U2 small nuclear RNAs, and only in the latter case requires the ...

RNAi Factors Are Present and Active in Human Cell Nuclei
Cell Reports, 2014 RNAi is widely appreciated as a powerful regulator of mRNA translation in the cytoplasm of mammalian cells. However, the presence and activity of RNAi factors in the mammalian nucleus has been the subject of considerable debate.

Nanosecond electric pulses penetrate the nucleus and enhance speckle formation [PDF]
, 2007 Nanosecond electric pulses generate nanopores in the interior membranes of cells and modulate cellular functions. Here, we used confocal microscopy and flow cytometry to observe Smith antigen antibody (Y12) binding to nuclear speckles, known as small ...

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.

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 ...
