PSMB9 and cancer: As a result, the EBNA1 protein (expressed in all the EBV-associated malignant tumors), the signaling membrane proteins LMP1 (oncogene implicated in cell transformation and survival) and LMP2 (regulator of virus reactivation from latency) as well as the non-coding RNAs (implicated in immune escape rather than cell transformation) represent promising targets for the composition of an anti-EBV therapeutic vaccine (Dasari et al., 2019; Münz, 2019).
