Alteration of cell energy metabolism represents a major determinant of cancer progression; however, our understanding of oncogenic mechanisms underlying this rewiring remains elusive. In this issue of Cell Metabolism, Kurmi et al. (2018) show that HER2 signaling promotes ABL-mediated phosphorylation of the mitochondrial creatine kinase (MtCK1), providing ATP to support breast tumor growth.
