title: Antigenic and structural studies on the transforming proteins of Rous sarcoma virus and Yamaguchi 73 avian sarcoma virus.
abstract: A widely cross reactive antiserum raised against denatured pp60v-src, the transforming protein encoded by Rous sarcoma virus, was used to test antigenic relationships with the transforming gene products encoded by other avian sarcoma viruses. The results showed that P90gag-yes, the transforming protein of a representative of Class III avian sarcoma viruses, is antigenically related to pp60v-src. Tryptic phosphopeptide analysis of P90gag-yes revealed two phosphotyrosine-containing peptides and one phosphoserine-containing peptide. One of the phosphotyrosine-containing peptides comigrated with the phosphotyrosine-containing tryptic peptide from pp60v-src.
