Balancing between cuproplasia and copper-dependent cell death: molecular basis and clinical implications of ATOX1 in cancer

Abstract excerpt

as it functions within the CTR1-ATOX1-ATP7A/ATP7B axis. For this reason, ATOX1 plays a key role in preventing copper toxicity. Since copper ions have been shown to regulate the activity of a subset of other signaling proteins, ATOX1 can support cell proliferation, migration, and survival. Notably, ATOX1 is the only identified copper chaperone that has transcription factor activity. In this respect, CCND1, MDC1,...
