For example, infection of Epstein–Barr virus (EBV), hepatitis B virus (HBV), hepatitis C virus (HCV), human papillomavirus (HPV), and Kaposi sarcoma-associated herpesvirus (KSHV) were reported to result in changes in YAP protein levels through various mechanisms such as activation of the YAP promoter or inhibition of YAP protein degradation [13–17]. Here, YAP1 is linked to infection.
