Deinococcus proteolyticus MRP genome sequencing project
MRP
To identify mRNA substrates for the human RNase MRP complex, we examined the effects of siRNA-mediated depletion of RNase MRP (and RNase P) on the transcriptome of HEp-2 cells. The expression of two RNase MRP protein components, hPop1 and Rpp40, was knocked-down and after 48 hours mRNA was isolated ...

Mechanistic studies have revealed ribonuclease (RNase) MRP, a conserved RNA-based enzyme, is crucial for the maturation of ribosomal RNA in eukaryotes. However, the composition and RNA substrate specificity of this multisubunit ribonucleoprotein complex in higher eukaryotes remain unknown. Here, we ...

This series of microarrays compares gene expression by the bacterial pathogen Proteus mirabilis when the transcriptional regulator mrpJ is deleted or induced to levels found during experimental urinary tract infection. The enteric bacterium Proteus mirabilis is associated with a significant number ...

Composition and RNA binding specificity of metazoan RNase MRP
RNase MRP and RNase P are evolutionarily related complexes that facilitate rRNA and tRNA biogenesis, respectively. The two enzymes share nearly all protein subunits and have evolutionarily related catalytic RNAs. Notably, RNase P includes a unique subunit, RPP21, whereas no RNase MRP-specific protei...

Ribonuclease (RNase) MRP is a conserved RNA-based enzyme that is essential for maturation of ribosomal RNA (rRNA) in eukaryotes. However, the composition and RNA substrate specificity of this multisubunit ribonucleoprotein complex in higher eukaryotes remain a mystery. Here, we identify NEPRO and C1...

Reversible proliferative arrest induced by rapid depletion of RNase MRP
A new method of combining macro-porous reversed phase (mRP) protein fractionation with reversed phase liquid chromatography (RPLC) peptide separation tandem mass spectrometry (MS/MS) is reported for profiling the phosphoproteome of a complex sample. In this method, an mRP-C18 column was used to frac...
