title: Neoplastic transformation by E26 leukemia virus is mediated by a single protein containing domains of gag and myb genes.
abstract: The genome of avian leukemia virus E26 shares homology with v-myb, the oncogene of avian myeloblastosis virus, and encodes a protein with an Mr of 135,000. Analyses of tryptic oligopeptides show that this protein is related to the proteins encoded by gag (Pr76gag) as well as v-myb (p45v-myb[AMV] ) and c-myb (p75c-myb). We found no evidence for the existence of additional myb-related proteins or subgenomic species of myb-related RNA in myeloblasts transformed by strain E26.
