Abstract From the Canadian patent

The R1 subunit of herpes simplex virus (HSV) ribonucleotide reductase which , is expressed very early after viral reactivation possesses an N-terminal , domain of about 350 amino acids of unknown function. Using an adenovirus (Ad) inducible system we had demonstrated that a complete deletion of this domain produces a cytotoxic protein. We now report that apoptotic death induced by this truncated R1 could be completely prevented by coexpression of the fulllength R1. The R1 antiapoptotic activity was further substantiated by showing that expression of this protein at low level can completely block apoptosis induced either by TNF-receptor family triggering in the presence of …
