CHEK1 (Checkpoint Kinase 1) is a serine/threonine protein kinase that plays a central role in the DNA damage response (DDR).ated by ATR in Activ response to replication stress and DNA lesions, CHEK1 coordinates cell cycle arrest, DNA repair, and cell survival decisions. It is a critical regulator of genomic stability and is implicated in both cancer development and neurodegenerative diseases.
CHEK1 contains functional domains:
CHEK1 is activated by:
CHEK1 phosphorylates numerous targets:
CHK1 inhibitors are used in cancer therapy:
Research on CHEK1 Protein 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.
