Human nucleolar protein SURF6/RRP14 participates in early steps of pre-rRNA processing. [PDF]
The biogenesis of ribosomes requires tightly controlled transcription and processing of pre-rRNA which comprises ribosomal RNAs forming the core of large and small ribosomal subunits.

HIV-1 infection causes a down-regulation of genes involved in ribosome biogenesis. [PDF]
HIV-1 preferentially infects CD4+ T cells, causing fundamental changes that eventually lead to the release of new viral particles and cell death. To investigate in detail alterations in the transcriptome of the CD4+ T cells upon viral infection, we ...

Regulation of Pre-rRNA Processing in Plant: Mechanisms, Plasticity, and Developmental Implications [PDF]
Ribosome biogenesis is a fundamental process underlying plant growth, development, and environmental adaptation, and processing of precursor rRNA (pre-rRNA) represents one of its most critical regulatory steps.

Reconstitution of the complete pathway of ITS2 processing at the pre-ribosome
Excision of internal transcribed spacer 2 (ITS2) within eukaryotic pre-ribosomal RNA is essential for ribosome function. Here, the authors reconstitute the entire cycle of ITS2 processing in vitro using purified components, providing insights into the ...

SIRT7-dependent deacetylation of the U3-55k protein controls pre-rRNA processing [PDF]
SIRT7 is a protein deacetylase with important roles in rRNA synthesis, ribosome biogenesis and cell proliferation. Here the authors show a role of SIRT7 in rRNA maturation via deacetylation of U3-55k, a core component of the U3 snoRNP complex.

The human nucleolar protein FTSJ3 associates with NIP7 and functions in pre-rRNA processing. [PDF]
NIP7 is one of the many trans-acting factors required for eukaryotic ribosome biogenesis, which interacts with nascent pre-ribosomal particles and dissociates as they complete maturation and are exported to the cytoplasm.

Human RNase H1 is associated with protein P32 and is involved in mitochondrial pre-rRNA processing. [PDF]
Mammalian RNase H1 has been implicated in mitochondrial DNA replication and RNA processing and is required for embryonic development. We identified the mitochondrial protein P32 that binds specifically to human RNase H1, but not human RNase H2. P32 binds
