The RNA5SP361 gene is a small nucleolar RNA (snoRNA) gene that belongs to the class of small non-coding RNAs involved primarily in the modification and processing of ribosomal RNA (rRNA). Here’s a detailed overview of the gene, along with additional information to address your queries.

### 1. Associated Genes:
While specific associations of RNA5SP361 with other genes may not be explicitly documented in NCBI and UniProt, small nucleolar RNAs generally interact with ribosomal RNA precursors and may be connected with other snoRNA genes. Also, snoRNAs can be involved in the regulation of various protein-coding genes, thereby potentially associating indirectly with genes involved in ribosome biogenesis, cell proliferation, and growth. More extensive studies or databases may be required to identify specific co-expressed or co-regulated genes directly linked to RNA5SP361.

### 2. Aging and Age-Related Diseases:
As of 2023, there is limited specific research directly linking RNA5SP361 to aging or age-related diseases in significant detail. However, snoRNAs, in general, are known to play roles in the regulation of gene expression and ribosome biogenesis, processes that can be disrupted in age-related diseases such as cancer and neurodegenerative diseases. There may be potential implications for RNA5SP361 in these contexts, but further targeted research would be required to elucidate any direct connections.

### 3. Drug Interactions:
Currently, there are no widely recognized drugs or drug classes explicitly known to interact with the RNA5SP361 gene. However, because snoRNAs play regulatory roles in rRNA synthesis and processing, drugs targeting ribosome biogenesis or affecting epigenetic modifications might indirectly influence the activity of snoRNAs, including RNA5SP361. Specific investigative studies into the pharmacological modulation of snoRNA functions are sparse.

### 4. Pathways and Biological Processes:
RNA5SP361 is generally involved in:
- **Ribosome Biogenesis**: Being a snoRNA, RNA5SP361 may participate in the modification and maturation of rRNA, ultimately contributing to ribosome assembly.
- **RNA Processing**: It plays a role in the processing of rRNA precursors, which is critical for efficient protein synthesis.
- **Cell Growth and Proliferation**: The regulation or production of ribosomal components directly impacts cellular growth rates and functions.

Overall, snoRNAs like RNA5SP361 are integral to fundamental cellular functions, but the details surrounding specific associations, implications in aging, drug interactions, and biological pathways require further research and may be available in more specialized databases or ongoing studies.
