Drosophila CG3303 is an essential endoribonuclease linked to TDP-43-mediated neurodegeneration [PDF]
Endoribonucleases participate in almost every step of eukaryotic RNA metabolism, acting either as degradative or biosynthetic enzymes. We previously identified the founding member of the Eukaryotic EndoU ribonuclease family, whose components display ...

Control of expression of the RNases J1 and J2 in bacillus subtilis [PDF]
In Bacillus subtilis, the dual activity 5' exo- and endoribonucleases J1 and J2 are important players in mRNA and stable RNA maturation and degradation. Recent work has improved our understanding of their structure and mechanism of action and identified ...

Sequence-specific endoribonucleases
Ribonucleases are nucleolytic enzymes that commonly occur in living organisms and act by cleaving RNA molecules. These enzymes are involved in basic cellular processes, including the RNA maturation that accompanies the formation of functional RNAs, as well as RNA degradation that enables removal of defective or dangerous molecules or ones that have ...

Pdxdc1 modulates prepulse inhibition of acoustic startle in the mouse. [PDF]
Current antipsychotic medications used to treat schizophrenia all target the dopamine D2 receptor. Although these drugs have serious side effects and limited efficacy, no novel molecular targets for schizophrenia treatment have been successfully ...

Identification of small RNAs abundant in Burkholderia cenocepacia biofilms reveal putative regulators with a potential role in carbon and iron metabolism [PDF]
Small RNAs play a regulatory role in many central metabolic processes of bacteria, as well as in developmental processes such as biofilm formation. Small RNAs of Burkholderia cenocepacia, an opportunistic pathogenic beta-proteobacterium, are to date not ...

Synthesis of 5’ end-labeled RNA
5’ end-labeled RNA molecules are useful substrates to analyse the endo- and exonucleolytic activities of various ribonucleases. Here two protocols are given to synthesize P32 labeled RNAs with a 5’ PPP or 5’ P moiety. 5’ exoribonucleases generally do not

Substrate specificity of bacterial endoribonuclease toxins
Bacterial endoribonuclease toxins belong to a protein family that inhibits bacterial growth by degrading mRNA or rRNA sequences. The toxin genes are organized in pairs with its cognate antitoxins in the chromosome and thus the activities of the toxins are antagonized by antitoxin proteins or RNAs during active translation.

Caenorhabditis elegans RIG-I Homolog Mediates Antiviral RNA Interference Downstream of Dicer-Dependent Biogenesis of Viral Small Interfering RNAs. [PDF]
Dicer enzymes process virus-specific double-stranded RNA (dsRNA) into small interfering RNAs (siRNAs) to initiate specific antiviral defense by related RNA interference (RNAi) pathways in plants, insects, nematodes, and mammals.

Structural Biology of the Arterivirus nsp11 Endoribonucleases [PDF]
ABSTRACT Endoribonuclease (NendoU) is unique and conserved as a major genetic marker in nidoviruses that infect vertebrate hosts. Arterivirus nonstructural protein 11 (nsp11) was shown to have NendoU activity and play essential roles in the viral life cycle.

Toxin-mediated ribosome stalling reprograms the Mycobacterium tuberculosis proteome
MazF endoribonucleases are thought to arrest growth of Mycobacterium tuberculosis by global translation inhibition. Here, Barth et al. show that MazF-mt9 cleaves a specific tRNA, leading to ribosome stalling at AAA codons and thus selective mRNA ...
