Hfq binding changes the structure of Escherichia coli small noncoding RNAs OxyS and RprA, which are involved in the riboregulation of rpoS [PDF]

, 2013
: OxyS and RprA are two small noncoding RNAs (sRNAs) that modulate the expression of rpoS, encoding an alternative sigma factor that activates transcription of multiple Escherichia coli stress-response genes.

RNA quality control: degradation of defective transfer RNA [PDF]

The EMBO Journal, 2002
The distinction between stable (tRNA and rRNA) and unstable (mRNA) RNA has been considered an important feature of bacterial RNA metabolism. One factor thought to contribute to the difference between these RNA populations is polyadenylation, which promotes degradation of unstable RNA.

A new yeast poly(A) polymerase complex involved in RNA quality control [PDF]

, 2005
Eukaryotic cells contain several unconventional poly(A) polymerases in addition to the canonical enzymes responsible for the synthesis of poly(A) tails of nuclear messenger RNA precursors.

Contribution of RNA Degradation to Intrinsic and Extrinsic Noise in Gene Expression.

Cell Reports, 2019
Genetically identical cells contain variable numbers of molecules, even if the cells share the same environment. This stochastic variability is prominent when molecules have low abundance, which is the case for mRNA noise.

DegNorm: normalization of generalized transcript degradation improves accuracy in RNA-seq analysis

Genome Biology, 2019
RNA degradation affects RNA-seq quality when profiling transcriptional activities in cells. Here, we show that transcript degradation is both gene- and sample-specific and is a common and significant factor that may bias the results in RNA-seq analysis ...

Trim25 is an RNA-specific activator of Lin28a/TuT4-mediated uridylation [PDF]

, 2014
RNA binding proteins have thousands of cellular RNA targets and often exhibit opposite or passive molecular functions. Lin28a is a conserved RNA binding protein involved in pluripotency and tumorigenesis that was previously shown to trigger TuT4-mediated

Xp54 and related (DDX6-like) RNA helicases : roles in messenger RNP assembly, translation regulation and RNA degradation [PDF]

, 2006
The DEAD-box RNA helicase Xp54 is an integral component of the messenger ribonucleoprotein (mRNP) particles of Xenopus oocytes. In oocytes, several abundant proteins bind pre-mRNA transcripts to modulate nuclear export, RNA stability and translational ...

Identification and analysis of the RNA degrading complexes and machinery of Giardia lamblia using an in silico approach

BMC Genomics, 2011
Background RNA degradation is critical to the survival of all cells. With increasing evidence for pervasive transcription in cells, RNA degradation has gained recognition as a means of regulating gene expression.
