cDNA cloning with a retrovirus expression vector: generation of a pp60c-src cDNA clone

Abstract

We used a murine retroviral expression vector, containing a genomic clone of the chicken c-src gene, a bacterial origin of replication, and a selectable marker, to remove 10 introns from the c-src gene. All 10 introns were removed accurately, and no mutations were introduced. The processed gene encoded a functional pp60c-src protein tyrosine kinase.
