Heo et al. [11] demonstrated that CDK1‐mediated TFCP2L1 phosphorylation is associated with tumorigenic stemness features and pluripotency in bladder cancer, while Michowski et al. [12] revealed that CDK1 functions to phosphorylate various epigenetic regulators and maintain the epigenetic identity of embryonic stem cells. Here, TFCP2L1 is linked to urinary bladder carcinoma.
