The avian sarcoma virus PRCII (Poultry Research Centre No. 2) transforms fibroblastsin vitroand causes fibromyxosarcomasin vivo. These growths develop after a longer period of latency than Rous sarcomas. PRCII is defective in replication and depends upon an associated helper virus, PRCII AV, for the production of infectious progeny. PRCII AV contains both subgroup A and B envelope determinants. Nonproducer cells transformed in single infection with PRCII do not release viral particles detectable by[3H]uridine incorporation or by reverse transcriptase assay. However, transforming virus can be rescued following super-infection with helper viruses of the chicken leukosis group. Immune precipitation analyses show that PRCII-transformed nonproducer cells do not synthesize the three replicative gene products, Pr76gag, Pr180gag-pol, and gPr95env, but contain a virus-specific protein of 105,000 molecular weight. This PRCII-p105 is precipitable with anti-gagserum, but not with anti-polserum, anti-envserum, or a broadly reactive anti-srcserum. No evidence was found for the expression of p60srcin PRCII-transformed cells. PRCII thus represents a new class of avian sarcoma virus distinct from Rous sarcoma virus and its relatives. In the accompanying paper[Neilet al., Virology107, 000 (1980)] we present evidence that PRCII-p105 contains novel sequences not encoded by other transforming oncoviruses.
