**PSME2P1 Gene Overview:**

The PSME2P1 gene is categorized as a pseudogene and is part of the proteasome subunit family. Pseudogenes are sequences that resemble normal genes but typically have lost their ability to code for proteins due to mutations or deletions. Consequently, they often serve regulatory functions or might be involved in the evolution of gene families.

### 1. Associated Genes:
While specific associations with other genes may not be documented in the summaries, genes related to proteasome function or regulation may interact with PSME2P1. Here are a few examples:

- **PSME2**: This gene encodes a protein that is a part of the 26S proteasome complex and may have functional interactions with PSME2P1.
- **PSMB** genes (such as PSMB1, PSMB4): These are also components of the proteasome and might share regulatory environments or be involved in similar biological processes.

### 2. Aging and Age-Related Diseases:
There is limited direct information available about PSME2P1 in relation to aging or specific age-related diseases. However, because proteasome function is crucial for protein degradation and cellular homeostasis, dysfunction in proteasome-related processes can lead to the accumulation of damaged proteins, which is a hallmark of aging and various age-related diseases (e.g., neurodegenerative disorders).

Studies suggest that proteasome activity might influence longevity and may be associated with diseases that affect aging populations, although the specific contribution of PSME2P1 remains to be defined.

### 3. Drug Interactions:
Currently, there is no specific drug or drug class explicitly known to interact directly with PSME2P1 due to its classification as a pseudogene. That said, compounds affecting the proteasome's activity, such as proteasome inhibitors (e.g., bortezomib), might indirectly relate to the context in which PSME2P1 functions, but specific evidence linking these directly to PSME2P1 is sparse.

### 4. Pathways and Biological Processes:
PSME2P1 does not encode a functional protein due to its pseudogene status, so it is not involved in specific pathways or biological processes in the conventional sense. However, since it is related to the proteasome family, pathways in which proteasome subunits are involved can be noted, including:

- **Protein Catabolism**: The proteasome plays a vital role in degrading ubiquitinated proteins, crucial for cellular regulation and homeostasis.
- **Cell Cycle Regulation**: Proteasomes are essential for the removal of cell cycle regulators.
- **Antigen Processing**: The proteasome is involved in the generation of peptides for presentation by MHC class I molecules.

### Summary:
Overall, PSME2P1 is a pseudogene associated with the proteasome complex. Most insights into its involvement in biological processes and age-related implications arise from its relationship to functional proteasome genes rather than direct effects or known interactions. Further studies may illuminate any possible roles this pseudogene could play in health and disease context.
