Merve Demir,*, Laura Koepping, Ya Li, Lynn Fujimoto, Andrey Bobkov, Jianhua Zhao, Taro Hitosugi, Eduard Sergienko Structure, 2024 [link] Mitochondrial creatine kinases (MtCKs) are key players in maintaining energy homeostasis in cells that work with cytosolic creatine kinases for energy transport from mitochondria to cytoplasm. The inhibition of breast cancer growth by cyclocreatine targeting CKs indicates dependence of cancer cells on the energy shuttle for cell growth and survival.
