The RNA5SP90 gene encodes a small RNA molecule known as a 5S ribosomal RNA (rRNA) gene, and it is part of the larger family of ribosomal RNA genes that plays a crucial role in the formation and function of ribosomes, which are essential for protein synthesis in all living cells. Below is a detailed compilation of information regarding the RNA5SP90 gene, including aspects you requested:

### General Information
- **Gene Symbol**: RNA5SP90
- **Function**: RNA5SP90 is a member of the 5S rRNA family, which is essential for the assembly and function of ribosomes. These small nucleolar RNAs are involved in the scaffolding of ribosomal components and contribute to the overall stability and function of the ribosome during translation.

### 1. Associated Genes
RNA5SP90 acts within the context of other genes involved in ribosome biogenesis and protein synthesis. However, specific associated genes are generally not detailed for the RNA5SP90 gene but may include:
- **Other 5S rRNA genes** (e.g., RPS5, RPL5)
- **Genes involved in ribosomal protein components** like RPL and RPS families.

Further association may also exist with genes related to the cell cycle and stress responses that influence ribosomal activity and degradation.

### 2. Aging and Age-Related Diseases
While specific direct associations between RNA5SP90 and aging or age-related diseases are not well documented, components of the ribosome, including rRNA, are implicated in various age-related changes:
- **Cellular stress responses**: Alterations in ribosomal biogenesis and efficiency have been linked to aging.
- **Cancer and genetic disorders**: Disruptions in ribosome biogenesis, including rRNA processing, can lead to disorders including certain cancers, which are often differentiated by age.

### 3. Drug Interactions
Currently, there are no specific drugs or drug classes categorized to interact exclusively with RNA5SP90. However:
- **Antibiotics targeting ribosomal RNA**: A class of drugs, such as macrolides (e.g., azithromycin), may interact indirectly by targeting the ribosome's function, which is affected by rRNA integrity.
- **Potential cancer therapeutics**: Since disruptions in ribosome assembly can lead to oncogenic pathways, compounds that enhance or inhibit ribosome function might indirectly be relevant.

### 4. Pathways and Biological Processes
RNA5SP90 is involved in various critical biological processes, including:
- **Ribosome biogenesis**: A core process by which ribosomal RNA is synthesized and assembled with ribosomal proteins.
- **Translation regulation**: By being a crucial component of the ribosomal machinery, it participates in the overall regulation of translation.
- **ncRNA metabolism**: It is part of the broader class of non-coding RNAs that play various roles in gene expression regulation and modulation.

### Conclusion
RNA5SP90 is a significant component of the ribosomal RNA family and plays an essential role in the processes underlying protein synthesis and ribosome integrity. Its implications in aging and association with other genes, aunque not extensively characterized, suggest it is critical in cellular functioning and health. Further investigations may clarify its roles in disease pathways and potential therapeutic targets.
