### CENPT Gene Overview

**Gene Symbol:** CENPT

**Protein Summary:**
The CENPT gene encodes a protein that is a vital component of the CENPA-NAC (nucleosome-associated complex), pivotal for kinetochore assembly, which is crucial for accurate chromosome segregation during cell division (mitosis). Specifically, it facilitates the recruitment of CENPA-CAD complex, aiding the incorporation of newly synthesized CENPA (Centromere Protein A) into centromeres. CENPT is also a part of the heterotetrameric CENP-T-W-S-X complex, which binds and supercoils DNA, contributing significantly to kinetochore assembly. Functionally, CENPT plays an essential role in maintaining chromosome organization and ensuring progression through mitosis.

### 1. Associated Genes
CENPT interacts with or is associated with several other gene products, including:
- **CENPA** (Centromere Protein A): Crucial for centromere structure and function.
- **CENPB** (Centromere Protein B): Another centromere protein involved in kinetochore formation.
- **CENPC** (Centromere Protein C): Important for anchoring proteins to the centromere.
- **CENPS**, **CENPW**, and **CENPX**: Other components of the CENP-T-W-S-X complex, contributing to centromere integrity and function.

### 2. Aging and Age-Related Diseases
As of the last information update in October 2023, there is limited direct evidence linking CENPT to aging or specific age-related diseases. However, the protein's role in mitotic progression suggests that dysregulation of CENPT could contribute to cellular senescence and age-related genomic instability, potentially impacting cancer development and other age-associated genomic disorders.

Research indicates that errors in chromosome segregation, linked to the function of CENPT and associated proteins, may lead to aneuploidy, a condition that often increases with age and is characteristic of many age-related diseases, including various cancers.

### 3. Drug Interactions
There are currently no specific drugs or drug classes directly targeting CENPT listed in standard databases. However, due to its vital role in mitosis and kinetochore function, drugs that affect cell division or impact microtubule dynamics (like taxanes and vinca alkaloids) could indirectly influence the pathways involving CENPT. Further research is required to elucidate any direct effects of specific pharmacological interventions on CENPT function or regulation.

### 4. Pathways and Biological Processes
CENPT is involved in several critical pathways and biological processes, including but not limited to:
- **Cell Cycle Regulation:** Especially during mitosis, CENPT ensures correct chromosome segregation.
- **Kinetochore Assembly:** It is fundamental in the assembly of the inner kinetochore, which is crucial for stable microtubule attachment.
- **Chromosome Segregation:** CENPT participates in processes linked to the proper distribution of chromosomes during cell division.
- **DNA-binding:** As part of the CENP-T-W-S-X complex, CENPT is involved in DNA supercoiling and structural maintenance of chromosomes.

### Conclusion
CENPT plays a pivotal role in kinetochore structure and function, impacting processes that are critical for cellular division. Its relationships with other centromere-associated proteins, coupled with its potential implications for genome stability and aging, underscore its importance in both fundamental biology and the study of age-related conditions. Further research could unveil more about its interactions, potential pathologies related to dysregulation, and therapeutic targets associated with its function.
