RNA G-quadruplex structures control ribosomal protein production
Scientific Reports, 2021 Four-stranded G-quadruplex (G4) structures form from guanine-rich tracts, but the extent of their formation in cellular RNA and details of their role in RNA biology remain poorly defined.

Methylation of ribosomal RNA by NSUN5 is a conserved mechanism modulating organismal lifespan
Nature Communications, 2015 Several pathways modulating longevity and stress resistance converge on translation by targeting ribosomal proteins or initiation factors, but whether this involves modifications of ribosomal RNA is unclear.

Ribosomal RNA regulates chromosome clustering during mitosis
Cell Discovery, 2022 Noncoding RNAs are known to associate with mitotic chromosomes, but the identities and functions of chromosome-associated RNAs in mitosis remain elusive. Here, we show that rRNA species associate with condensed chromosomes during mitosis.

Slip of grip of a molecular motor on a crowded track: Modeling shift of reading frame of ribosome on RNA template [PDF]
EPL, vol.114, 68005 (2016), 2016 We develop a stochastic model for the programmed frameshift of ribosomes synthesizing a protein while moving along a mRNA template. Normally the reading frame of a ribosome decodes successive triplets of nucleotides on the mRNA in a step-by-step manner.

Ribosomal transcription is regulated by PGC-1alpha and disturbed in Huntington’s disease
Scientific Reports, 2017 PGC-1α is a versatile inducer of mitochondrial biogenesis and responsive to the changing energy demands of the cell. As mitochondrial ATP production requires proteins that derive from translation products of cytosolic ribosomes, we asked whether PGC-1α ...

Molecular interactions between the constituents of small ribosomal subunit [PDF]
arXiv, 2012 Availability of high-resolution crystal structures of ribosomal subunits of different species opens a route to investigate about molecular interactions between its constituents and stabilization strategy. Structural analysis of the small ribosomal subunit shows that primary binder proteins are mainly employed in stabilizing the folded ribosomal RNA by ...

Methylation of Ribosomal RNA: A Mitochondrial Perspective
Frontiers in Genetics, 2020 Ribosomal RNA (rRNA) from all organisms undergoes post-transcriptional modifications that increase the diversity of its composition and activity. In mitochondria, specialized mitochondrial ribosomes (mitoribosomes) are responsible for the synthesis of 13
