Target Information
The tumor suppressor protein p53 is a sequence-specific transcription factor activated by cellular stress. It mediates cell cycle arrest or apoptosis in response to DNA damage or nutrient deprivation. p53 up-regulates stress response genes, including p21waf1, contributing to G1 or G2/M cell cycle arrest.
Structurally, p53 contains:
- N-terminal transactivation domain
- Central DNA-binding domain
- Oligomerisation domain
- C-terminal regulatory domain
Phosphorylation at Ser15 is crucial for activation and stabilization, while Ser392 phosphorylation is associated with tumor formation. p53 plays a key role in preventing proliferation of damaged cells and acts as an anticancer agent. It is also linked to aging, oxidative stress, and cognitive function (LTP deficits). Mutations in the TP53 gene can lead to loss of tumor suppressor activity and are common in various human cancers, including familial Li-Fraumeni syndrome.
