The SKP1P3 gene, also known as the "S-phase kinase-associated protein 1 pseudogene 3," is a member of a group of pseudogenes that are derived from the SKP1 gene, which is an important component of the SCF (SKP1-Cullin-F-box protein) ubiquitin ligase complex involved in protein ubiquitination, degradation, and cell cycle regulation.

### 1. Associated Genes
While the specific associated genes for SKP1P3 may vary in literature, variants or close relatives that interact with SKP1 include:
- **SKP1**: The functional gene from which SKP1P3 is derived.
- **CUL1**: A key component of the SCF complex that works alongside SKP1.
- **FBXO proteins**: Members of the F-box protein family which also form part of the SCF complex.

### 2. Aging and Age-Related Diseases
Currently, specific studies associating SKP1P3 with aging or age-related diseases are limited. However, given SKP1’s involvement in cellular processes such as cell cycle regulation and protein degradation, dysregulation of these pathways due to altered pseudogene expression could hypothetically contribute to aging and senescence. Additionally, the ubiquitin-proteasome system's efficiency declines with age, leading to the accumulation of damaged proteins, which may indirectly implicate SKP1P3 in age-related processes.

### 3. Drug Interactions
As of the current understanding, there are no specific drugs or drug classes that are directly known to interact with SKP1P3. Given that it is a pseudogene, it is less likely to be a direct target for drugs compared to functional genes. However, potential indirect interactions could occur via drugs that target the SCF ubiquitin ligase complex or pathways involved in cellular protein degradation and turnover.

### 4. Pathways and Biological Processes
The SKP1P3 gene’s role is primarily associative due to its pseudogene status; however, it is relevant to:
- **Cell Cycle Regulation**: By regulation of proteins involved in the cell cycle, despite being a pseudogene.
- **Proteasome-mediated Degradation**: It may influence the dynamics of protein degradation indirectly.
- **Ubiquitin-mediated Proteolysis**: As part of the pathway network related to the functions of the SKP1 gene and the SCF complex.

In summary, while SKP1P3 has limited direct functional implications due to its pseudogene nature, it is associated with various cellular processes linked to its functional counterpart, SKP1, and possibly has broader implications in aging and related pathways, although more research is needed to elucidate these connections robustly.
