RESUMO
Recombinant adenoviruses bearing the avian c-src gene and polyomavirus middle-T-antigen gene were isolated and used to simultaneously overexpress both proteins in human 293 cells. Cells overexpressing both proteins had greater middle-T-antigen-associated tyrosine kinase activity than cells overexpressing only middle T antigen. By contrast, the intrinsic pp60c-src tyrosine kinase activity was not greater in cells overexpressing both proteins than in cells overexpressing only pp60c-src. This system of simultaneous overexpression provides a means of obtaining large quantities of pp60c-src, middle T antigen, and the complex between them.
