CHEK1 (Checkpoint Kinase 1) encodes a serine/threonine kinase that plays a central role in the DNA damage response (DDR). It is activated by ATR (Ataxia Telangiectasia and Rad3-related) in response to replication stress and DNA lesions. CHEK1 is essential for maintaining genomic stability and has been implicated in neurodegenerative diseases including ALS and Parkinson's disease.

Key functions include:
CHEK1 is expressed ubiquitously:
Research on CHEK1 Gene has revealed important connections between DNA repair mechanisms and neurodegenerative diseases. Studies have shown that variants in DNA repair genes can influence susceptibility to Parkinson's disease and ALS, potentially through effects on mitochondrial function and cellular stress responses.
The protein encoded by this gene plays a role in maintaining genomic stability, and dysregulation may contribute to the accumulation of DNA damage in neurons over time. This has implications for understanding the molecular basis of neurodegeneration and developing therapeutic interventions.
CHEK1 is a master regulator of the DNA damage response, linking replication stress to cell cycle arrest and DNA repair.
