The transcription factor NFAT (nuclear factor of activated T cells) controls the expression of
many immunomodulatory proteins. African swine fever virus inhibits proinflammatory
cytokine expression in infected macrophages, and a viral protein A238L was found to
display the activity of the immunosuppressive drug cyclosporin A by inhibiting NFAT-
regulated gene transcription in vivo. This it does by binding the catalytic subunit of
calcineurin and inhibiting calcineurin phosphatase activity.
