title: [A member of the SRC gene family, the c-erbB-1 gene, is closely related to the EGF receptor gene].
abstract: An avian erythroblastosis virus, AEV-H, induces both erythroblastosis and sarcomas in susceptible chickens. Since AEV-H carries the v-erbB as a sole oncogene, the erbB gene was suggested to be responsible for the induction of these tumors. Analysis of the amino acid sequence predicted from the nucleotide sequence of the v-erbB gene revealed that the gene product has a domain characteristic for tyrosine kinase. Recently in has been suggested has the v-erbB protein is a part of the chicken EGF (epidermal growth factor) receptor. Using antibody against either v-erbB protein or EGF receptor, we also demonstrated close similarity between the two proteins. Further studies on human genomic DNA revealed that the c-erbB-1 gene, a proto-oncogene of the v-erbB gene, is the EGF receptor gene. We were also able to identify the c-erbB-2 gene that seems to code for a EGF receptor-like protein with a domain for tyrosine kinase. Finally, we would like to show that cell lines established from human squamous cell carcinom are frequently associated with amplification of the c-erbB-1/EGF receptor gene.
