The **HSP90B3P** gene is a pseudogene related to the heat shock protein 90 family. Here’s a summary based on the information provided and additional details:

### HSP90B3P Gene Overview
- **Gene Symbol**: HSP90B3P (HSP90B member 3 pseudogene)
- **Type**: Pseudogene (a non-functional segment of DNA that resembles a gene)

### 1. Associated Genes
While specific genes associated directly with HSP90B3P are not frequently mentioned, it is often linked to other heat shock protein genes in functional contexts. Some associated genes could include:
- **HSP90AA1** (Heat Shock Protein 90 Alpha Family Class A Member 1)
- **HSP90AB1** (Heat Shock Protein 90 Alpha Family Class B Member 1)
- **HSPA1A** (Heat Shock 70kDa Protein 1A)
- **HSPB1** (Heat Shock Protein Beta 1)

These genes generally belong to the heat shock protein family and are involved in protein folding and stress response mechanisms.

### 2. Aging and Age-Related Diseases
Currently, there is limited direct information regarding the association of HSP90B3P with aging or age-related diseases. However, heat shock proteins (HSPs) in general, including those related to HSP90, are known to play roles in cellular stress responses, which have implications for aging and age-related pathology, such as neurodegenerative diseases and cancer. Dysregulation of heat shock proteins may impact cellular proteostasis, which can contribute to the aging process.

### 3. Drug Interactions
As HSP90B3P is a pseudogene, it is not expected to directly interact with drugs or drug classes. However, its functional relatives, especially HSP90 proteins, are significant drug targets:
- **HSP90 Inhibitors**: Drugs designed to inhibit HSP90, such as:
  - **Tanespimycin (17-AAG)** - an investigational drug that is a heat shock protein 90 inhibitor.
  - **Picropodophyllin** - another specific inhibitor.

### 4. Pathways and Biological Processes
The HSP90 family, which includes functional relatives rather than the pseudogene itself, is involved in numerous cellular pathways:
- **Protein folding**: Assists in the correct folding of proteins.
- **Response to stress**: Crucial for the cellular response to various stress conditions (heat shock, oxidative stress).
- **Cell cycle regulation**: Interacts with various oncogenic signaling pathways to influence cell cycle progression.
- **Vesicular transport**: May be involved in intracellular transport mechanisms.

Overall, while HSP90B3P itself does not have a direct functional role, its related members in the HSP90 family are critical in many physiological and pathological processes, and research into these pathways can provide insight into their implications in health and disease.
