Cancer cells can produce asparagine, yet both the regulation and biological functions of asparagine are unclear. Here the authors show that p53 suppresses asparagine synthesis and disrupts asparagine-aspartate homeostasis contributing to tumor growth inhibition, and that asparagine and aspartate modulates AMPK-mediated p53 activation by physically binding to and regulating LKB1.
