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.

Decoding the role of the RNA binding activity of p53 [PDF]
p53 is a key tumour suppressor, mutated in over half of cancers. p53’s ability to form extensive protein interactions, along with its function as a sequence-specific transcription factor, are well documented due to their roles in canonical p53 tumour ...

Human telomerase RNA-protein interactions [PDF]
Telomere length is maintained in most eukaryotic cells by telomerase. The core components of this ribonucleoprotein (RNP) enzyme include a protein catalytic subunit, composed of motifs conserved among reverse transcriptases (RT), and an RNA subunit that contains a short template sequence essential for the synthesis of telomeric repeats. We developed an

An improved method for surface immobilisation of RNA: application to small Non-Coding RNA - mRNA pairing [PDF]
Characterisation of RNA and its intermolecular interactions is increasing in importance as the inventory of known RNA functions continues to expand. RNA-RNA interactions are central to post-transcriptional gene regulation mechanisms in bacteria, and the ...

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

Maf1-mediated repression of RNA polymerase III transcription inhibits tRNA degradation via RTD pathway [PDF]
tRNA precursors, which are transcribed by RNA polymerase III, undergo end-maturation, splicing and base modifications. Hypomodified tRNAs, such as tRNAVal(AAC), lacking 7-methylguanosine and 5-methylcytidine modifications, are subject to degradation by a

RNA Protein Interaction in Neurons [PDF]
Neurons have their own systems for regulating RNA. Several multigene families encode RNA binding proteins (RNABPs) that are uniquely expressed in neurons, including the well-known neuron-specific markers ELAV and NeuN and the disease antigen NOVA. New technologies have emerged in recent years to assess the function of these proteins in vivo, and the ...

Methods to study RNA–protein interactions [PDF]
Noncoding RNA sequences, including long noncoding RNAs, small nucleolar RNAs, and untranslated mRNA regions, accomplish many of their diverse functions through direct interactions with RNA-binding proteins (RBPs). Recent efforts have identified hundreds of new RBPs that lack known RNA-binding domains, thus underscoring the complexity and diversity of ...

A splicing-dependent transcriptional checkpoint associated with prespliceosome formation [PDF]
There is good evidence for functional interactions between splicing and transcription in eukaryotes, but how and why these processes are coupled remain unknown.

L11 domain rearrangement upon binding to RNA and thiostrepton studied by NMR spectroscopy [PDF]
Ribosomal proteins are assumed to stabilize specific RNA structures and promote compact folding of the large rRNA. The conformational dynamics of the protein between the bound and unbound state play an important role in the binding process.
