Disruption of epigenetic regulation in host cells is a common evasion strategy used by viruses(Ozturkler and Kalkan 2021).Recently,Kee et al.(2022)reported that accessory protein ORF8 of SARS-CoV-2 can diffuse into the cell nucleus and mimic histone H3 through the ARKS motif,thereby interfering with H3 post-translational modifications(PTMs),disrupting gene transcription,and diminishing the antiviral response.
