Abstract

We studied the expression of a molecularly cloned human c-src gene, c-src-1, localized on chromosome 20, whose coding region consists of 11 exons and spans a 19.5-kilobase (kb) distance. Using a replication-competent retroviral vector derived from molecularly cloned Rous sarcoma virus DNA (pSRA-2), we obtained two constructs: one (pSR-CS) carrying the unmodified human c-src coding sequence and another (pSR-CVS) with a chimeric gene formed between the human c-src gene and the carboxy-terminal 12-amino acid v-src-specific coding sequence. From chicken embryo fibroblasts transfected with these DNA constructs, infectious viruses designated as WO CS and WO CVS, respectively, were recovered. WO CS virus did not cause cell transformation, whereas WO CVS induced cell transformation. Analyses of the proviral DNAs indicated that all introns were spliced out such that the 19-kb inserts were converted to 1.7-kb cDNA forms. Analyses of src proteins in infected cells, using monoclonal antibody MAb327 against v-src protein, showed the following results. The CVS and CS src proteins were about 60 and 61 kilodaltons in size, respectively; the specific protein kinase activity assayed in vitro of the CVS src protein was about 20-fold higher than that of the CS src protein and comparable to that of the v-src protein; the transforming CVS src protein reacted to an antibody against a v-src-specific peptide, whereas the CS src protein did not. These results indicate that the human c-src gene has a potential transforming ability and suggest that the v-src-specific sequence played an important role in the generation of Rous sarcoma virus.
