WebJan 18, 2024 · EZH2 Phosphorylation at T311 Correlates with Better Survival in Cancer Patients. AMPK serves as a cellular AMP/ATP sensor to maintain energy homeostasis; given its multifaceted functions in fine-tuning multiple metabolic pathways, its role in tumorigenesis is context dependent (Hardie, 2013). WebEzh2 is phosphorylated by cyclin-dependent kinase 1 (CDK1) at threonine residues 345 and 487 in a cell cycle-dependent manner. A phospho-mimic at residue 345 increased HOTAIR ncRNA binding to Ezh2, while the phospho-mimic at residue 487 was ineffectual.
