Nonmetabolic role for CKB in ferroptosis

The selenoprotein glutathione peroxidase 4 (GPX4) is the guardian of ferroptosis, a form of cell death earmarked by unrestrained lipid peroxidation. A new study shows that the metabolic enzyme creatinine kinase B (CKB) phosphorylates GPX4, which may influence the susceptibility of cancer cells to ferroptosis.
