Breakthrough discovery: Protein regulates p53 acetylation, unlocking new cancer treatments.
This research explored how a protein called Bat3/Scythe controls the acetylation of p53, a key player in DNA damage responses. They found that Bat3 is crucial for p53 to become acetylated when cells experience DNA damage, which is essential for p53 to work properly. When Bat3 is absent, p53 loses its acetylation ability, affecting its ability to activate important genes involved in responding to damaged DNA. By forming a complex with another protein called p300, Bat3 helps bring p53 to p300 for acetylation to occur. Without Bat3, this process is disrupted, leading to reduced gene activation and resistance to DNA damage-induced cell death. This study sheds light on a new role for Bat3 in regulating how cells react to DNA damage, emphasizing its importance in maintaining cellular health.
