Altered tyrosine 527 phosphorylation and mitotic activation of p60c-src.

Abstract excerpt

The tyrosine kinasee activity of p60c-src, the protein product of the c-src gene, increases during mitosis; this may be important in initiating at least some of the cellular changes that occur during this phase of the cell cycle. Although there is evidence that p60c-src is phosphorylated at several sites during mitosis, phosphorylation in vitro does not increase its kinase activity. We now report that the kinase...
