NUCKS1 is a nuclear protein with multiple domains:
- N-terminal domain: Contains potential phosphorylation sites
- Central region: Low complexity regions
- C-terminal region: Acidic domain
The protein is extensively phosphorylated by various kinases including casein kinase 2 (CK2) and cyclin-dependent kinases (CDKs).
NUCKS1 functions as a nuclear scaffold protein:
- Modulates chromatin structure
- Regulates RNA polymerase II activity
- Controls transcription factor function
- Participates in DNA repair mechanisms
- Regulates cell cycle checkpoints
- Maintains genomic stability
- Acts downstream of various signaling pathways
- Integrates cellular stress signals
- Altered expression in substantia nigra
- May affect dopaminergic neuron survival
- Possible role in α-synuclein pathology
- Dysregulated in AD brain
- May affect tau pathology through kinase pathways
- Altered in immune cells
- May affect demyelination
