miR-24 functions as tumor suppressor and radiosensitizer in NPC cells and xenografts by inhibiting Jab1 translation through targeting both the 3′ untranslated region (3′UTR) and 5′UTR of Jab1, leading to tumor growth inhibition, and sensitizes NPC tumors to radiation in vivo (Wang S. et al., 2016). Here, COPS5 is linked to nasopharyngeal carcinoma.
