Summary
Ribosome construction involves hierarchical folding of ribosomal RNA (rRNA) and assembly factors. This essay highlights the crucial, yet poorly understood, role of RNA tertiary contacts in precise ribosome formation.
Area of Science:
- Molecular Biology
- Biochemistry
- Structural Biology
Background:
- Eukaryotic ribosome construction is a complex, multi-step process.
- Nascent ribosomal RNA (rRNA) undergoes hierarchical folding and modular assembly.
- Ribosomal proteins and assembly factors aid in managing error-prone RNA folding.
Purpose of the Study:
- To elucidate the poorly understood process of establishing correct RNA tertiary contacts during ribosome formation.
- To highlight the importance of tertiary interactions in rRNA compaction and functional ribosome assembly.
Main Methods:
- Review of genetic studies.
- Biochemical analyses.
- Structural studies.
Main Results:
- Recent studies provide insights into nascent rRNA transformation into functional ribosomes.
- Understanding of how long-range tertiary interactions are orchestrated is emerging.
- The role of assembly factors in facilitating correct RNA folding is being uncovered.
Conclusions:
- Precise formation of functional ribosomes relies on the accurate establishment of RNA tertiary contacts.
- Further research into RNA tertiary interactions is critical for understanding ribosome biogenesis.
- This essay emphasizes the need for focused investigation into this specific aspect of ribosome assembly.

13.4K
Ribosome synthesis is a highly complex and coordinated process involving more than 200 assembly factors. The synthesis and processing of ribosomal components occurs not only in the nucleolus but also in the nucleoplasm and the cytoplasm of eukaryotic cells.
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...

Ribosomes translate genetic information encoded by messenger RNA (mRNA) into proteins. Both prokaryotic and eukaryotic cells have ribosomes. Cells that synthesize large quantities of protein—such as secretory cells in the human pancreas—can contain millions of ribosomes.

01:25Protein Folding
8.5K
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

The basic structure of RNA consists of a string of ribonucleotides attached by phosphodiester bonds. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.

01:34Directing Proteins to the Rough Endoplasmic Reticulum
7.4K
The organelle-specific signaling sequences direct proteins synthesized in the cytosol to their final destination like ER, mitochondria, peroxisomes, etc. Some of the proteins directed to ER are then trafficked via vesicles to other organelles within the cell or the extracellular environment through the Golgi complex. For example, the rough ER synthesizes soluble proteins for transportation to the lysosomes or secretion out of the cell. It can also synthesize transmembrane proteins that can...

03:00Molecular Chaperones and Protein Folding
18.4K
The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.
