### RPL23AP90 Gene Summary

**Gene Symbol:** RPL23AP90

**General Description:**
RPL23AP90 is a gene that encodes a protein potentially involved in ribosomal function due to its association with ribosomal protein genes. The specifics of its function remain under investigation, and as an auxiliary gene, it is related to the broader group of ribosomal protein genes.

### 1. Genes Associated with RPL23AP90
While the NCBI and UniProt summaries may not list specific associated genes, it is important to note that ribosomal protein genes are generally co-regulated. Other ribosomal proteins may be linked, such as:
- **RPL23** (Ribosomal Protein L23)
- **RPL23A** 
- **RPL23B**
- Various other ribosomal protein genes (like RPLs and RPSs) due to their shared functions in protein synthesis.

### 2. Aging and Age-Related Diseases
Research on RPL23AP90 in the context of aging or age-related diseases is limited. However, abnormalities in ribosomal proteins and their associated genes are often linked to:
- Ribosomopathies (disorders resulting from mutations in ribosomal gene/protein functions).
- Conditions such as Diamond-Blackfan anemia or certain cancers (due to ribosomal biogenesis defects) can show correlations with aging due to increased senescence and cellular dysfunction.

### 3. Drugs or Drug Classes
As of the latest data available, specific interactions between drugs and the RPL23AP90 gene have not been widely documented. However, as the gene is linked to ribosomal function, drugs that target protein synthesis, such as:
- **Antibiotics** (like aminoglycosides and macrolides that target bacterial ribosomal function).
- **Chemotherapeutic agents** (that might affect ribosomal assembly or function in malignancies) may indirectly relate to the effects on ribosomal proteins, including RPL23AP90. More targeted studies would be necessary for definitive interactions.

### 4. Pathways and Biological Processes
RPL23AP90 is associated with various biological processes, primarily due to its involvement in ribosomal activity:
- **Ribosome biogenesis:** The assembly of ribosomal subunits.
- **Translation:** The process of protein biosynthesis from mRNA, where ribosomal proteins play essential roles.
- Involvement in:
    - **Gene expression regulation:** This indirectly affects how proteins are synthesized, influencing cellular functions and overall physiology.
    - **Cell cycle regulation:** Ribosomal function is tightly regulated during cell division.

### Conclusion
Further research is needed to fully elucidate the roles of RPL23AP90, including its direct implications in aging, disease associations, and pharmacological interactions. As scientific understanding evolves, delve into the latest literature for potential updates on any emerging findings regarding this gene.
