Because USP7 mainly deubiquitinates and stabilizes Mdm2 in unstressed cells, we believe that WDR79 may stimulate the USP7-Mdm2 axis more effectively than the USP7-p53 counterpart, thereby facilitating the proliferation of NSCLC cells despite the functional antagonism between Mdm2 and p53. Here, WRAP53 is linked to non-small cell lung carcinoma.
