title: The membrane-binding domain and myristylation of p60v-src are not essential for stimulation of cell proliferation.
abstract: Previous studies showed that the amino-terminal domain of Rous sarcoma virus p60v-src involved in myristylation and membrane association of the protein is required for morphological transformation and anchorage independence. Analysis of src delection mutants revealed that the amino-terminal one-third of p60v-src, including the membrane-binding domain, is not essential for induction of cell proliferation. These results demonstrated that, in contrast to the cellular target(s) involved in morphological transformation and anchorage independence, the target(s) involved in mitogenic activity is accessible to nonmyristylated src proteins.
