For instance, CDK1-mediated pT345-EZH2 and pT487-EZH2 facilitate EZH2 ubiquitination degradation in breast cancer cell, cervical cancer cell and lung cancer cell [28, 30, 108]; JAK2 phosphorylates Y641-EZH2, leading to E3 ligase β-TrCP-mediated EZH2 degradation in lymphoma cell [48]; and CDK5 phosphorylation of EZH2 at T261 residue results in the E3 ubiquitin ligase FBW7-mediated degradation of EZH2 in pancreatic cancer cell [50]. This evidence concerns the gene FBXW7 and familial pancreatic carcinoma.
