Hexokinase 2 is an RNA-binding protein that regulates mRNA translation independently of glycolysis and induces melanoma cell proliferation
Hexokinase 2 (HK2) is traditionally known for its metabolic role in glycolysis. This study shows that it also functions as an RNA-binding protein that regulates mRNA translation, particularly of SOX10...
