The DIRAS1 gene (DIRAS family GTPase 1) encodes a member of the DIRAS family of GTPases, which are small GTP-binding proteins implicated in various cellular processes. Below is a detailed description of DIRAS1 along with the requested additional information.

### 1. Associated Genes
DIRAS1 has been associated with several other genes, particularly those involved in GTPase activity, signaling pathways, and cellular processes. Some of the notable genes include:
- **DIRAS2:** A homologous gene that is part of the DIRAS family and shares similar functions.
- **Ras:** As DIRAS1 is a GTPase, it may interact with other members of the Ras superfamily, which includes various Ras proteins that are key regulators of cell signaling.

### 2. Aging and Age-Related Diseases
Recent studies have begun to explore the role of DIRAS1 in aging and age-related diseases, with findings highlighting:
- **Cancer:** DIRAS1 has been studied for its potential involvement in tumor suppression. Alterations in its expression or function may contribute to specific cancer types, indicating a potential role in age-related cancer development.
- **Neurodegeneration:** Some studies suggest a possible link to neurodegenerative diseases, where altered signaling pathways involving GTPases, including DIRAS1, may contribute to age-related decline in cognitive functions. 

### 3. Drug Interactions
Currently, there are no specific drugs or drug classes directly known to target DIRAS1. However, due to its role in GTPase signaling and cellular processes, it may theoretically interact with:
- **Small molecule inhibitors of GTPases:** Such compounds target the GTP-bound forms of GTPases and could affect DIRAS1 activity indirectly.
- It's important for researchers to keep an eye on emerging literature as new drug interactions may be discovered over time.

### 4. Pathways and Biological Processes
DIRAS1 is involved in several key biological pathways and processes, including:
- **Cellular signaling pathways:** Given its GTPase activity, DIRAS1 plays a role in regulating intracellular signaling cascades.
- **Cell proliferation and differentiation:** It may be involved in cellular processes that affect cell growth and differentiation, contributing to normal developmental processes and potentially influencing tumorigenesis.
- **Neurodevelopmental pathways:** Emerging evidence suggests involvement in pathways critical for neuronal development and function, which may link it to neurological disorders.

Overall, DIRAS1 is a GTPase with roles in critical cellular processes, and ongoing research is likely to further elucidate its function, connections to diseases, and potential therapeutic applications.
