### TSPAN15 Gene Overview

**Gene Symbol:** TSPAN15  
**Location:** Chromosome 6  
**Gene Type:** Protein-coding gene  
**Protein Family:** Tetraspanins (Transmembrane 4 Superfamily)

### 1. Associated Genes
While the NCBI and UniProt summaries mention TSPAN15's interaction with the metalloprotease ADAM10 and its role in Notch signaling, there are other genes that are commonly associated with TSPAN15 due to its functional roles:
- **CDH2 (Cadherin 2):** As mentioned, TSPAN15 promotes ADAM10-mediated cleavage of CDH2.
- **ADAM10:** As the primary partner discussed above, it is involved in Notch signaling and other developmental processes.
- **Notch Receptors (e.g., NOTCH1):** The regulation of Notch signaling implies a relationship with its receptors and downstream effectors.
- **Other Tetraspanins:** Such as CD81, CD9, and CD37, which may have overlapping functions in signal transduction.

### 2. Aging and Age-Related Diseases
TSPAN15 has not been extensively researched specifically concerning aging or age-related diseases. However, since it is involved in regulating Notch signaling and ADAM10 activity, potential implications may exist as these pathways are known to be critical in various age-related conditions, including:
- **Neurodegenerative Diseases:** There is evidence that altered Notch signaling may be implicated in Alzheimer’s disease and other neurodegenerative disorders.
- **Cardiovascular Diseases:** Changes in cadherin signaling and ADAM10 activity can impact heart function and vascular development.
- **Cancer:** Aberrant Notch signaling is often associated with tumorigenesis, and TSPAN15's role in this pathway may suggest involvement in cancer progression.

### 3. Drug Interactions
As of the latest data, there are no specific drugs directly targeting TSPAN15. However, the pathways it influences may be susceptible to modulation by several classes of drugs:
- **Gamma-Secretase Inhibitors:** Since Notch signaling can be modulated via gamma-secretase, inhibiting this enzyme can indirectly affect TSPAN15’s role in regulating ADAM10 and Notch signaling.
- **ADAM10 Inhibitors:** Some experimental inhibitors targeting ADAM10's activity may have downstream effects on TSPAN15.
- **Anticancer Agents:** Compounds affecting Notch pathways, such as those utilized in targeted cancer therapies, may interact with TSPAN15-related functions.

### 4. Pathways and Biological Processes
TSPAN15 is involved in several key biological pathways and processes:
- **Signal Transduction:** Mediates signaling events affecting various cellular responses.
- **Cell Development and Activation:** Influences cell differentiation, activation, motility, and growth.
- **Cleavage of Cell Adhesion Molecules (e.g., CDH2):** Via the regulation of ADAM10.
- **Notch Signaling Pathway:** Negatively regulates ligand-induced Notch signaling, affecting cell fate decisions and maintenance of stem cells.
- **Cell-Cell Interactions:** Through its associations with other tetraspanins and adhesion molecules, TSPAN15 is implicated in enhancing cell-cell adhesion and communication.

### Conclusion
TSPAN15 is a versatile player in cellular signaling and interactions, with implications for developmental biology, neurobiology, and potentially age-related pathologies. Further research may elucidate its roles in aging and disease progression, as well as its potential as a therapeutic target.
