Novel endoribonucleases as central players in various pathways of eukaryotic RNA metabolism [PDF]
For a long time it has been assumed that the decay of RNA in eukaryotes is mainly carried out by exoribonucleases, which is in contrast to bacteria, where endoribonucleases are well documented to initiate RNA degradation.

Ribonuclease E strongly impacts bacterial adaptation to different growth conditions
Adaptation of bacteria to changes in their environment is often accomplished by changes of the transcriptome. While we learned a lot on the impact of transcriptional regulation in bacterial adaptation over the last decades, much less is known on the role

Processing of bacterial RNA [PDF]
Processing of RNA is a feature of RNA metabolism which contributes to the determination of the fmal population of active RNA molecules in the cell. Pro- cessing is the sum of events which converts a primary RNA transcript into a functional molecule. RNA processing in bacteria consists mainly of two parts, modification of nucleotides and cutting and ...

The Chloroplast Ribonucleoprotein CP33B Quantitatively Binds the psbA mRNA
Chloroplast RNAs are stabilized and processed by a multitude of nuclear-encoded RNA-binding proteins, often in response to external stimuli like light and temperature. A particularly interesting RNA-based regulation occurs with the psbA mRNA, which shows

Arabidopsis RanBP2-Type Zinc Finger Proteins Related to Chloroplast RNA Editing Factor OZ1
OZ1, an RNA editing factor that controls the editing of 14 cytidine targets in Arabidopsis chloroplasts, contains two RanBP2-type zinc finger (Znf) domains. The RanBP2 Znf is a C4-type member of the broader zinc finger family with unique functions and an

Molecular mechanisms of template-independent RNA polymerization by tRNA nucleotidyltransferases
The universal 3'-terminal CCA sequence of tRNA is built and/or synthesized by the CCA-adding enzyme, CTP:(ATP) tRNA nucleotidyltransferase. This RNA polymerase has no nucleic acid template, but faithfully synthesizes the defined CCA sequence on the 3 ...

Regulation of expression of human RNA polymerase II-transcribed snRNA genes [PDF]
In addition to protein-coding genes, RNA polymerase II (pol II) transcribes numerous genes for non-coding RNAs, including the small-nuclear (sn)RNA genes.

The requirement of Mettl3-promoted MyoD mRNA maintenance in proliferative myoblasts for skeletal muscle differentiation [PDF]
Myogenic progenitor/stem cells retain their skeletal muscle differentiation potential by maintaining myogenic transcription factors such as MyoD. However, the mechanism of how MyoD expression is maintained in proliferative progenitor cells has not been ...

Functional characterization of Ysh1p, the yeast endonuclease involved in 3" end processing and in transcription termination of RNA polymerase II transcripts [PDF]
Eukaryotic RNA polymerase II (RNAP II) is involved in the synthesis of two major classes of transcripts: messenger RNAs (mRNAs) and small nuclear and small nucleolar RNAs.
