ProteomicsComprehensive Nucleoside Analysis of Archaeal RNA Modification Profiles Reveals a m7G in the Conserved P-loop of 23S rRNA
Extremophilic archaea employ diverse chemical RNA modifications, providing a rich source of new enzymes for biotechnologically valuable RNA manipulations. Our understanding of the modified nucleoside profiles in Archaea, as well as the functions and dynamic regulation of specific RNA modifications i...

ProteomicsAnnotation of the genes responsible for helix 69 rRNA modifications in 23S of Bacillus subtilis.
A total of 25 modifications were mapped to 16S and 23S RNA in B. subtilis ribosome, however most of the genes responsible for these modification sites remain unknown. In this work, bottom-up oligonucleotide LC-MS/MS was used to detect rRNA modifications in five single gene knock-out strains: yydA, ...

ProteomicsR-protein composition of budding yeast PTC deficient 80S ribosomes
Ribosomal RNA modifications are introduced during ribosome assembly by snoRNA and stand-alone modification enzyme based mechanisms in budding yeast. Lack of individual modifications in rRNA has a minor effect on yeast growth, ribosome biogenesis, and translation, which has complicated the definition...

TranscriptomicsSnapshots of pre-rRNA structural flexibility reveal eukaryotic 40S assembly dynamics at nucleotide resolution
Ribosome assembly in eukaryotes involves the activity of hundreds of assembly factors that direct the hierarchical assembly of ribosomal proteins and numerous ribosomal RNA folding steps. However, detailed insights into the function of assembly factors and ribosomal RNA folding events are lacking. T...

ProteomicsComplete list of canonical post-transcriptional modifications in Bacillus subtilis ribosome.
Using bottom-up oligonucleotide LC-MS/MS in combination with stable isotope labeling, chemical derivatization, and bioinformatics variable modification search, a total of 25 modifications were mapped to the sequences of 16S and 23S RNA in B. subtilis. 10 modification sites, previously identified by ...

ProteomicsFGF2 antiproliferative stimulus triggers proteomic and transcriptional changes associated with nucleolar disorganization in K-ras-driven mouse tumor cells (Nucleoli TMT)
Chromatin plays a crucial role in the intermediation between cell signaling and gene expression. The nucleolus is sensitive to stress and can orchestrate a chain of cellular events in response to stress signals. Despite being a growth factor, FGF2 has anti-proliferative and tumor-suppressive functio...
