RESUMO
Avian erythroblastosis virus (AEV) is an oncogenic retrovirus of birds. The AEV-encoded erbB polypeptide, a transmembrane glycoprotein bearing an N-terminal domain exposed on the surface of virally transformed cells, plays a crucial role in AEV-mediated oncogenesis. We report here a characterization of a mutated form of the AEV erbB protein which lacks over two-thirds of the extracellular region of this oncogenic protein. This mutant v-erbB protein, although lacking the three possible extracellular sites of N-linked protein glycosylation, appears unimpaired in the ability to transform cells to an oncogenic phenotype.
