genes, erbb-1medical dictionary

Retrovirus-associated DNA sequences (erbb) originally isolated from the avian erythroblastosis virus (aev). The oncogene v-erbb arose by insertion of viral DNA into the c-erbb-1 proto-oncogene resulting in expression of a protein lacking the amino-terminal ligand-binding domain. V-erbb is the primary transforming gene of aev and abrogates the requirements for other mitogens. The proto-oncogene c-erbb-1 codes for the protein epidermal growth factor receptor (epidermal growth factor receptor-urogastrone). Overexpression of the gene occurs in a wide range of tumours, commonly squamous carcinomas of various sites and less commonly adenocarcinomas. The human c-erbb-1 gene is located at 7p12-13 on the short arm of chromosome 7.
