Purification of human transcription factor IIIC and its binding to the gene for ribosomal 5S RNA.
Transcription factor hTFIIIC was purified from cytoplasmic extracts of HeLa cells using four different chromatographic steps. This procedure yields a protein fraction which actively supports transcription in reconstitution assays and contains five major ...

Purification of 70S Ribosomes from Bacillus subtilis
The eubacterial ribosome (70S) is a macromolecular complex that is composed of a small (30S) subunit and a large (50S) subunit. The small subunit comprises the 16S ribosomal RNA (rRNA) and more than 20 ribosomal proteins (r-proteins), whereas the large ...

60S ribosome biogenesis requires rotation of the 5S ribonucleoprotein particle [PDF]
During eukaryotic ribosome biogenesis, nascent ribosomal RNA (rRNA) forms pre-ribosomal particles containing ribosomal proteins and assembly factors. Subsequently, these immature rRNAs are processed and remodelled.

In vitro Assessment of RNA Polymerase I Activity
In eukaryotic cells transcriptional processes are carried out by three different RNA polymerases: RNA polymerase I which specifically transcribes ribosomal RNA (rRNA), RNA polymerase II which transcribes protein-coding genes to yield messenger RNAs ...

Kinetoplastid Specific RNA-Protein Interactions in Trypanosoma cruzi Ribosome Biogenesis. [PDF]
RNA binding proteins (RBP) play essential roles in the highly conserved and coordinated process of ribosome biogenesis. Our laboratory has previously characterized two essential and abundant RBPs, P34 and P37, in Trypanosoma brucei which are required for

Essential Assembly Factor Rpf2 Forms Novel Interactions within the 5S RNP in
Ribosome biogenesis is a highly complex and conserved cellular process that is responsible for making ribosomes. During this process, there are several assembly steps that function as regulators to ensure proper ribosome formation.

Control of ribosome traffic by position-dependent choice of synonymous codons [PDF]
Messenger RNA encodes a sequence of amino acids by using codons. For most amino acids there are multiple synonymous codons that can encode the amino acid. The translation speed can vary from one codon to another, thus there is room for changing the ribosome speed while keeping the amino acid sequence and hence the resulting protein.
