Avian erythroblastosis virus (AEV) induces erythroblastosis and sarcomas in chickens. Two domains within the viral genome, erb-A and erb-B, have been implicated in AEV-mediated oncogenesis. By use of hybridization-arrested translations and hybridization-selections of mRNA, we have mapped on the viral genome the polypeptides specified by the erb domains. The results of hybridization-arrest with DNA representing the spliced 5' leader region of the AEV mRNA suggested that the authentic product of the erb-B domain was a 61,000 molecular weight protein, not a 41,000 molecular weight polypeptide previously identified.
