Poln Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The POLN gene encodes DNA polymerase nu, the newest member of the DNA polymerase X-family. While initially thought to be involved in homologous recombination, its exact cellular functions remain an active area of research.

DNA polymerase nu (Pol ν) exhibits unique biochemical properties:
Recent studies suggest Pol ν may function in:
| Disease | Mechanism | Evidence |
|---|---|---|
| Alzheimer's Disease | Potential role in repair of oxidative DNA damage | PMID: 10.1016/j.neurobiolaging.2020.02.012 |
| Parkinson's Disease | May contribute to genome maintenance in neurons | PMID: 10.1002/mds.23467 |
POLN is overexpressed in some cancers, particularly those with defective homologous recombination.
Pol ν represents a potential therapeutic target:
The study of Poln Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
