Our study uncovered that HectH9 drives glycolysis and tumor development by K63-linked ubiquitination of Hexokinase 2 (HK2). This mechanism is critical for HK2 localization to mitochondria for activating HK2’s functions in glycolysis promotion and apoptosis inhibition, suggesting that targeting HectH9 is a new strategy to tackle metabolism-addicted tumors.
