Ribosomal Protein S3: A KH Domain Subunit in NF-κB Complexes that Mediates Selective Gene Regulation

NF-kappaB is a DNA-binding protein complex that transduces a variety of activating signals from the cytoplasm to specific sets of target genes. To understand the preferential recruitment of NF-kappaB to specific gene regulatory sites, we used NF-kappaB p65 in a tandem affinity purification and mass spectrometry proteomic screen. We identified ribosomal protein S3 (RPS3), a KH domain protein, as...

Comprehensive mutational analysis of yeast DEXD/H box RNA helicases required for small ribosomal subunit synthesis.

The 17 putative RNA helicases required for pre-rRNA processing are predicted to play a crucial role in ribosome biogenesis by driving structural rearrangements within preribosomes. To better understand the function of these proteins, we have generated a battery of mutations in five putative RNA helicases involved in 18S rRNA synthesis and analyzed their effects on cell growth and pre-rRNA proce...

Both KH and non-KH domain sequences are required for polyribosome association of Scp160p in yeast.

Scp160p is a 160 kDa RNA-binding protein in yeast previously demonstrated to associate with specific messages as an mRNP component of both soluble and membrane-bound polyribosomes. Although the vast majority of Scp160p sequence consists of 14 closely spaced KH domains, comparative sequence analyses also demonstrate the presence of a potential nuclear localization sequence located between KH dom...

Human AATF/Che-1 forms a nucleolar protein complex with NGDN and NOL10 required for 40S ribosomal subunit synthesis

Mammalian AATF/Che-1 is essential for embryonic development, however, the underlying molecular mechanism is unclear. By immunoprecipitation of human AATF we discovered that AATF forms a salt-stable protein complex together with neuroguidin (NGDN) and NOL10, and demonstrate that the AATF-NGDN-NOL10 (ANN) complex functions in ribosome biogenesis. All three ANN complex members localize to nucleoli...

The KRR1 gene encodes a protein required for 18S rRNA synthesis and 40S ribosomal subunit assembly in Saccharomyces cerevisiae.

The newly discovered Saccharomyces cerevisiae gene KRR1 (YCL059c) encodes a protein essential for cell viability. Krr1p contains a motif of clustered basic amino acids highly conserved in the evolutionarly distant species from yeast to human. We demonstrate that Krr1p is localized in the nucleolus. The KRR1 gene is highly expressed in dividing cells and its expression ceases almost completely w...
