The **ANAPC1P3** gene is a member of the ANAPC1 family, which is associated primarily with cell cycle regulation and controlling the anaphase-promoting complex (APC) in eukaryotic organisms. Below is a more detailed description based on your requirements:

### 1. Associated Genes
While the provided summaries may not list specific associated genes, ANAPC1P3 is related to other members of the ANAPC (Anaphase Promoting Complex) family, which can include:
- **ANAPC1** (Anaphase Promoting Complex Subunit 1)
- **ANAPC4** (Anaphase Promoting Complex Subunit 4)
- **ANAPC5** (Anaphase Promoting Complex Subunit 5)
- **ANAPC15** (Anaphase Promoting Complex Subunit 15)
These genes function collaboratively in the regulation of the cell cycle and protein degradation pathways.

### 2. Aging and Age-related Diseases
While there may not be extensive direct literature focusing solely on ANAPC1P3 in the context of aging or age-related diseases, dysregulation in the components of the anaphase-promoting complex, which ANAPC1P3 is part of, is often linked to various cancers and potentially other age-related diseases. Proper function of the APC is critical for maintaining genome stability, and disruptions can lead to aneuploidy and other genomic alterations frequently observed in age-associated pathologies.

### 3. Drug Interactions
Currently, there are no specific drugs or drug classes directly associated with ANAPC1P3. However, given its involvement in cell cycle regulation, it may be indirectly related to drugs that target cell cycle checkpoints, such as:
- **Chemotherapeutic agents** (e.g., taxanes, anthracyclines), which may impact the processes mediated by the APC.
- **Inhibitors of the cell cycle**, including those that affect Cyclin-dependent kinases (CDKs).

### 4. Pathways and Biological Processes
ANAPC1P3 is primarily involved in several cellular pathways and biological processes including, but not limited to:
- **Cell Cycle Regulation**: Particularly in the transition from metaphase to anaphase, wherein the APC is crucial for the degradation of cell cycle regulators.
- **Protein Ubiquitination**: As part of the anaphase-promoting complex, ANAPC1P3 facilitates ubiquitin-mediated degradation of target proteins, ensuring proper cell cycle progression.
- **Mitotic Regulation**: Plays a role in ensuring accurate chromosome segregation during mitosis.

Given the complexity of cellular processes, continuing research may uncover more about ANAPC1P3's roles and gene interactions that are vital for maintaining cellular homeostasis and its implications for health and disease, particularly with aging.
