### CENPP Gene Overview

**Gene Symbol:** CENPP  
**Function:** CENPP encodes a protein that is a component of the CENPA-CAD complex at the centromere. This protein plays a crucial role in the assembly of kinetochore proteins, ensuring proper mitotic progression and chromosome segregation. It is speculated that CENPP is involved in the incorporation of newly synthesized CENPA (centromeric histone H3 variant) into centromeres, facilitated by its interaction with the CENPA-NAC (CENPA-nucleosome assembly complex).

### 1. Associated Genes
While the summaries specifically mention the CENPA and CENPA-NAC complexes, other relevant genes often associated with CENPP due to their involvement in similar cellular processes or pathways include:
- **CENPA:** Coding for centromeric histone protein.
- **CENPB:** Another protein associated with the centromeric region.
- **CENPC:** Coding for centromere protein C, which is important for proper kinetochore function.
- **KIF2C:** Associated with microtubule dynamics during cell division.

### 2. Aging and Age-Related Diseases
Research regarding the specific role of CENPP in aging is currently limited, but defects in centromeric function and chromosome segregation have been associated with age-related diseases, particularly cancer. Abnormalities in the function or expression of proteins within the CENPA-CAD complex may contribute to genomic instability, which is a hallmark of aging and age-associated diseases, including:
- **Cancer:** Defective chromosome segregation can lead to aneuploidy, a common characteristic of many cancers.

### 3. Drug Interactions
As of my last training data through October 2023, no specific drugs or drug classes have been directly linked to interactions with the CENPP gene or its protein product. However, drugs targeting pathways involved in mitosis or those used for cancer therapy may indirectly affect CENPP activity through their overall effects on chromosome segregation or mitotic processes.

### 4. Pathways and Biological Processes
CENPP is involved in several important biological processes and pathways, including:
- **Cell Cycle Regulation:** Specifically, it plays a role in mitosis by ensuring proper kinetochore assembly and function.
- **Chromosome Segregation:** Essential for accurate distribution of chromosomes to daughter cells during cell division.
- **Histone Incorporation:** Involved in the incorporation of histone variants (like CENPA) into chromatin at the centromere.

### Conclusion
In summary, the CENPP gene is a critical component of the machinery ensuring accurate chromosome segregation during cell division. While its associations with aging and drug interactions require further exploration, its role in genetic stability positions it as a significant player in both cellular function and potential pathology related to age-related diseases. Ongoing research may elucidate more detailed pathways and functional associations.
