ribosome assembly

Definition

Target type: biologicalprocess

The aggregation, arrangement and bonding together of the mature ribosome and of its subunits. [GOC:ma, PMID:30467428]

Ribosome biogenesis is a complex and highly regulated process that involves the coordinated assembly of ribosomal RNA (rRNA) and ribosomal proteins (r-proteins) into functional ribosomes. These molecular machines are essential for protein synthesis, a fundamental process in all living cells. Here's a detailed description of the process:

1. **Transcription of rRNA:** The genes encoding rRNA are located in the nucleolus, a specialized region within the nucleus. RNA polymerase I transcribes the rRNA genes, producing a large precursor rRNA molecule.

2. **Processing of rRNA:** The precursor rRNA undergoes a series of processing steps, including cleavage and modification. These steps are carried out by a variety of enzymes, including ribonucleases (RNases) and methyltransferases.

3. **Synthesis of r-proteins:** The genes encoding r-proteins are located throughout the genome and are transcribed by RNA polymerase II. The resulting mRNAs are translated into r-proteins in the cytoplasm.

4. **Assembly of ribosomal subunits:** The processed rRNA and r-proteins associate with each other in a stepwise manner to form the two ribosomal subunits: the small (40S) and large (60S) subunits.

5. **Import of ribosomal subunits:** The small and large subunits are transported from the nucleus to the cytoplasm, where they are ready for protein synthesis.

6. **Ribosome assembly factors:** A number of assembly factors are involved in the process of ribosome assembly. These factors facilitate the proper folding of rRNA and r-proteins, the association of subunits, and the export of ribosomes from the nucleus.

7. **Quality control:** During ribosome assembly, there are quality control mechanisms that ensure the proper assembly of the ribosomal subunits. Defective subunits are degraded, preventing the formation of non-functional ribosomes.

8. **Ribosome biogenesis is regulated:** The process of ribosome biogenesis is tightly regulated, ensuring that the cell produces the correct number of ribosomes to meet its needs. This regulation is achieved through a variety of mechanisms, including transcription factors, signaling pathways, and feedback loops.

In summary, ribosome assembly is a multi-step process involving transcription, processing, translation, and assembly. This intricate process is essential for protein synthesis and cell viability.'
