### RNA5SP87 Gene Overview
The **RNA5SP87** gene encodes a small nucleolar RNA (snoRNA) that is involved in the biogenesis of ribosomal RNA (rRNA) and modification processes critical for ribosome assembly. SnoRNAs typically function within the nucleolus and play essential roles in the maturation and modification of rRNA.

### Associated Genes
While the specific NCBI and UniProt summaries may not mention specific associated genes, snoRNA genes are commonly found in clusters with other snoRNA genes. For RNA5SP87, you may find associations with other small nucleolar RNAs like those located in the same genomic context or those that interact in ribosome biogenesis, such as:

- Other members of the snoRNA family, particularly those in the same C/D box or H/ACA box categories.
- Protein-coding genes involved in ribosome assembly or nucleolar structure, which may include ribosomal protein genes.

### Aging and Age-Related Diseases
The role of snoRNA in cellular processes is critical for maintaining cellular function, and disturbances in these processes can lead to age-related diseases. Specific details about RNA5SP87 may not be well documented directly concerning aging or age-related diseases, but the overall dysfunction of snoRNAs has been implicated in:

- **Cancer:** Abnormal snoRNA expression is often observed in various types of cancer.
- **Neurodegenerative diseases:** Dysregulation in ribosome biogenesis and rRNA processing is sometimes associated with conditions such as Alzheimer's disease and other neurodegenerative disorders.

### Drug Interactions
As of the last comprehensive updates, there are no specific drugs directly targeting RNA5SP87 documented in major databases. While snoRNAs themselves are not traditional drug targets, investigators have explored how modulating ribosome biogenesis can impact cellular stress responses and survival in cancer or other conditions, suggesting that drugs aimed at related pathways could indirectly affect the function of RNA5SP87.

### Pathways and Biological Processes
RNA5SP87 is primarily involved in several key biological processes, including, but not limited to:

- **Ribosome biogenesis:** Integral to the assembly and maturation of ribosomes.
- **RNA processing:** Plays a role in the modification of precursor rRNAs, including methylation and pseudouridylation.
- **Nucleotide binding:** Involved in the processing and modification of RNA substrates.
  
Additionally, snoRNAs like RNA5SP87 may contribute to cellular responses to stress, thereby influencing pathways related to cell growth, proliferation, and differentiation.

### Summary
RNA5SP87 is a small nucleolar RNA implicated in critical cellular functions related to ribosome biogenesis and rRNA modification. Although associated genes directly relevant to RNA5SP87 may be difficult to pinpoint without specific co-expression analysis, its implications in aging and disease response mechanisms contribute to an understanding of its biological significance. While no drugs specifically target RNA5SP87, the pathways it influences are vital for maintaining cellular health, particularly in the context of age-related processes.
