**Gene Overview: SMARCE1P3**

The SMARCE1P3 gene is a pseudogene, associated with the SMARCE1 gene, which encodes a component of the SWI/SNF chromatin-remodeling complex. Pseudogenes are generally non-functional sequences that may arise from gene duplication or retrotransposition. Here’s what is currently understood about the SMARCE1P3 gene based on the latest information as of October 2023:

### 1. Associated Genes:
While specific interactors for SMARCE1P3 may not be explicitly documented in the summaries you referenced, it is commonly associated with the following related genes:
- **SMARCE1**: The functional coding gene from which SMARCE1P3 is derived.
- **Other members of the SWI/SNF complex**, including:
  - SMARCA4 (BRG1)
  - SMARCD1
  - SMARCB1 (INI1)
These genes collectively contribute to chromatin remodeling and gene expression regulation.

### 2. Aging and Age-Related Diseases:
The literature surrounding pseudogenes, including SMARCE1P3, is limited regarding direct associations with aging or age-related diseases. However, the functional SMARCE1 gene is implicated in cellular processes that can influence aging, such as:
- **Chromatin remodeling dynamics**: Changes in chromatin structure can affect gene expression during aging.
- **Genomic stability**: Proper chromatin function is essential for maintaining stability and preventing age-related diseases such as cancer.

While the direct role of SMARCE1P3 in these processes is not well characterized, its relationship with the SMARCE1 gene may suggest potential indirect associations through modulation of chromatin structure.

### 3. Drug Interactions:
No specific drugs or drug classes are currently known to interact directly with the SMARCE1P3 gene. However, agents affecting the SWI/SNF complex as a whole, particularly those targeting SMARCE1 or associated chromatin remodeling proteins, may have implications. Some notable class of drugs that may influence these pathways includes:
- **Epigenetic modifiers**: Such as histone deacetylase (HDAC) inhibitors, which can affect the function and regulation of chromatin remodeling complexes and could indirectly relate to the actions of associated pseudogenes.

### 4. Pathways and Biological Processes:
The SMARCE1P3 pseudogene may be involved in chromatin remodeling processes by virtue of its association with the SMARCE1 gene. Here are some relevant pathways and biological processes:
- **Chromatin remodeling (SWI/SNF complex pathways)**: These pathways are critical for transcription regulation, DNA repair, and maintenance of genomic integrity.
- **Cell differentiation**: Given the role of chromatin remodeling in enabling gene expression patterns necessary for differentiation.
- **Gene expression regulation**: Maintaining the active vs. repressed states of genes, particularly during development and in response to environmental signals.
- **Cell cycle progression**: Involving roles in cell division and response to DNA damage, which can relate to aging processes.

In summary, while SMARCE1P3 is a pseudogene with limited direct functional characterization, it plays a role in chromatin-related processes where relationships with aging and cellular health are noteworthy through its associated pathways and interactions with functioning chromatin remodelers. Further research could provide insights into its specific functions and implications in health and disease.
