Vanadates 63-71 SRC proto-oncogene, non-receptor tyrosine kinase Gallus gallus 119-128 2436039-5 1987 4:1471-1477, 1985) suggest that vanadate may enhance a cellular regulatory mechanism that inhibits the activity of pp60c-src in normal cells. Vanadates 32-40 SRC proto-oncogene, non-receptor tyrosine kinase Gallus gallus 115-124 2436039-9 1987 Assuming that pp60c-src is inhibited intracellularly by vanadate, either another tyrosine kinase is stimulated by vanadate (e.g., a growth factor receptor) or the 36-kilodalton phosphoprotein in normal cells is no longer rapidly dephosphorylated by a tyrosine phosphatase in the presence of vanadate.
