### Gene Overview
**Gene Symbol**: TCP1P3  
**Full Name**: T-complex protein 1, subunit 3 (TCP1) pseudogene 3

TCP1P3 is a pseudogene located on chromosome 5. Pseudogenes are sequences that are similar to known genes but are typically non-functional due to mutations or other changes. TCP1 specifically has a role in the chaperone function, primarily involved in protein folding and assembly. The TCP1 gene family is known for its essential role in the formation of the cytosolic chaperonin complex.

### Associated Genes
While specific interactions and associations with other genes are often context-specific, common analysis often pairs TCP1 family members and genes involved in heat shock responses or protein folding. Since TCP1P3 is a pseudogene, significant direct interactions may be limited, but it is generally related to the following associations:

- **TCP1**: The functional gene from which TCP1P3 is derived.
- **HSPs (Heat Shock Proteins)**: Particularly HSP60 and HSP70, as they also play roles in protein folding and are often mentioned in relation to chaperonins.
- **Other members of the TCP1 complex**, like TCP1, TCP2, etc., may also be considered in broader functional studies.

### Aging and Age-Related Diseases
While TCP1P3 itself is a pseudogene and lacks direct evidence for functional roles that inform on aging or age-related diseases, its associated functions and the context of TCP1 are relevant. Dysregulation of protein folding mechanisms, of which the TCP1 family is part, is often implicated in various age-related diseases, including:

- **Neurodegenerative diseases**: Such as Alzheimer’s disease and Parkinson’s disease, where protein misfolding plays a critical role.
- **Cancer**: Changes in chaperone function can also relate to tumorigenesis as alterations in protein folding can have significant downstream effects.

### Drug Interactions
As TCP1P3 is a pseudogene, it is unlikely to have direct drug interactions or be a target for specific drugs. However, the functional properties of its parent gene and related proteins might play indirect roles in pathways influenced by various drug classes, including:

- **HSP activators/inhibitors**: Drugs targeting heat shock proteins may have an impact on related chaperonins as a whole but would not specifically target TCP1P3.
- **Cancer therapeutics**: Medications aimed at cells exhibiting misfolded proteins and associated pathways could indirectly impact any regulatory mechanisms where TCP1 is active.

### Pathways and Biological Processes
TCP1P3 itself does not participate in canonical pathways given its pseudogenomic status, but it represents elements involved in:

- **Protein folding and assembly**: Contributing indirectly to any processes where the cytosolic chaperonin complex is essential.
- **Heat shock response**: Engaged in the general response to stress, particularly under conditions of cellular stress.
  
### Summary
TCP1P3 is a pseudogene associated with TCP1 and implicated in protein folding processes through its related gene family. While aging and age-related mechanisms may touch on discussions surrounding TCP1P3 due to protein misfolding, the pseudogene itself does not have established drug interactions or pathways beyond what could be extrapolated from its functional counterparts. Understanding the broader context of the chaperonin complex might provide additional insight into its indirect relevance in therapeutic and aging associations.
