Atr is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
ATR is a gene/protein encoding a key neuronal protein involved in synaptic function, signal transduction, and cellular homeostasis. Dysfunction of ATR is associated with neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, and related disorders.
ATR is a key kinase for replication stress and DNA damage response:
- Replication stress response: Activated by stalled replication forks
- S-phase checkpoint: Prevents replication collapse
- DNA repair: Coordinates repair of lesions
- Chromatin remodeling: Modifies chromatin state
- Transcription regulation: Affects global transcription
- Altered ATR signaling in ALS
- Replication stress in motor neurons
- DNA replication stress in neurons
- ATR activation in AD brain
- Genotoxic stress in dopaminergic neurons
- Ubiquitously expressed
- High proliferation tissues, neurons

The study of Atr 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.
