Abstract
Two vIRF4 (Kaposi's-sarcoma-associated-herpesvirus vIRF4) peptides, vif1, corresponding to aa202-216 of vIRF4, and vif2, corresponding to aa220-236 of vIRF4, are potent and selective HAUSP antagonists. The vif1 and vif2 peptides robustly suppress HAUSP DUB enzymatic activity, ultimately leading to p53-mediated anti-cancer activity. The vif1 and vif2 peptides, along with their homologues, are useful in treating ALL.
