Mapping targets for small nucleolar RNAs in yeast [PDF]

Wellcome Open Research, 2018
Background: Recent analyses implicate changes in the expression of the box C/D class of small nucleolar RNAs (snoRNAs) in several human diseases. Methods: Here we report the identification of potential novel RNA targets for box C/D snoRNAs in budding yeast, using the approach of UV crosslinking and sequencing of hybrids (CLASH) with the snoRNP proteins

The Disordered Region of ASXL1 Acts as an Auto‐Regulator Through Condensation

Advanced Science, EarlyView.
ASXL1's long IDR encodes an electrostatic “basic platform + acidic brake” that autoregulates condensation. Truncation at a clinical hotspot lifts this brake, forming condensates that retarget BRD2, remodel local chromatin accessibility, and impair neutrophil maturation.

snOPY: a small nucleolar RNA orthological gene database [PDF]

BMC Research Notes, 2013
Abstract Background Small nucleolar RNAs (snoRNAs) are a class of non-coding RNAs that guide the modification of specific nucleotides in ribosomal RNAs (rRNAs) and small nuclear RNAs (snRNAs). Although most non-coding RNAs undergo post-transcriptional modifications prior to maturation, the functional significance of ...

Small Nucleolar RNA Snord17 Promotes Self‐Renewal of Intestinal Stem Cells through Yy2 mRNA Export and Tead4 Activation

Advanced Science, EarlyView.
Snord17, through interaction with Thoc3, promotes nuclear export and translation of Yy2 mRNA in Snord17+/+ ISCs. The Yy2 protein subsequently binds the Tead4 promoter to promote its transcription, activating Hippo signaling, which is essential for ISC maintenance.

snR30/U17 Small Nucleolar Ribonucleoprotein: A Critical Player during Ribosome Biogenesis

Cells, 2020
The small nucleolar RNA snR30 (U17 in humans) plays a unique role during ribosome synthesis. Unlike most members of the H/ACA class of guide RNAs, the small nucleolar ribonucleoprotein (snoRNP) complex assembled on snR30 does not direct pseudouridylation

Characterization of a novel trypanosomatid small nucleolar RNA [PDF]

Nucleic Acids Research, 1998
Trypanosomes possess unique RNA processing mechanisms including trans- splicing of pre-mRNA and RNA editing of mitochondrial transcripts. The previous finding of a trimethylguanosine (TMG) capped U3 homologue in trypanosomes suggests that rRNA processing may be related to the processing in other eukaryotes.

Connexin 26 Functions as a Direct Transcriptional Regulator During the Cochlea Development

Advanced Science, EarlyView.
Connexin26 can not only form intercellular channels that mediate rapid communication on the cell membrane, but also enter the nucleus as a transcription factor to directly regulate the transcription of nuclear genes. In the developing cochlea, Cx26 can control the maturation of the molecular scissor ADAM10 by regulating the transcription of TspanC8 ...

Molecular Mechanisms and Clinical Implications of Noncoding RNAs in Cancer

Non-Coding RNA
Noncoding RNAs (ncRNAs), which include small nuclear RNAs (snRNAs), small nucleolar RNAs (snoRNAs), microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), are RNA molecules that arise from genomic regions without protein-coding ...

C/D-Box Snord105b Promotes Tumorigenesis in Gastric Cancer via ALDOA/C-Myc Pathway

Cellular Physiology and Biochemistry, 2018
Background/Aims: Small nucleolar RNAs (snoRNAs) play an important role in carcinogenesis. In this study, we identified a C/D box snoRNA, snord105b, and further investigated the function and mechanism of the snord105b in gastric cancer (GC).

Engineered Ripening-Specific Accumulation of Polyamines Spermidine and Spermine in Tomato Fruit Upregulates Clustered C/D Box snoRNA Gene Transcripts in Concert with Ribosomal RNA Biogenesis in the Red Ripe Fruit

Plants, 2020
Ripening of tomato fruit leads, in general, to a sequential decrease in the endogenous levels of polyamines spermidine (SPD) and spermine (SPM), while the trend for the diamine putrescine (PUT) levels is generally an initial decrease, followed by a ...
