I read that

[SARS-CoV-2 has] a nonstructural protein called NSP3, a component of which blocks the host’s efforts to fight off the virus. In particular, this protein shuts down host enzymes called PARPs, which prevent viruses from replicating, and interferes with cellular calls for the release of virus-fighting immune proteins called interferons.

I'm somewhat acquainted with interferons, but I'm trying to better understand the part about PARPs. Alas the Wikipedia page on these does not mention an anti-viral-[replication] function. So, how do PARPs stop viruses from replicating? (Is it by triggering cell death?)
