Mitogenesis by v-Src: a need for active oncoprotein both in leaving G0 and in completing G1 phases of the cell cycle.


Activation of the tyrosine kinase of a temperature sensitive v-Src mutant of Rous sarcoma virus in quiescent Rat-1 cells leads to passage through the cell cycle. This is accompanied by a transient increase of the DNA binding activity of the transcription factor AP-1 which is not sufficient for the v-Src mediated cell cycle traverse. There is another need… (More)
