问题解答问：什么是癌基因蛋白？答：癌基因的生物活性是通过其表达蛋白起作用的，它们是细胞正常生长、增殖和分化的调节剂，当其过度表达或表达异常时，因调控失常引起癌变。按其生物学功能，癌基因蛋白有生长因子、生长因子受体及蛋白激酶、ＧＴＰ结合蛋白、核蛋白等，... Question Answer Q: What is an oncogene protein? A: The biological activity of oncogenes works through their expressed proteins. They are regulators of normal growth, proliferation and differentiation of cells. When they are overexpressed or abnormally expressed, they cause canceration due to abnormal regulation. According to its biological function, oncogene proteins include growth factor, growth factor receptor and protein kinase, GTP binding protein, nuclear protein, etc.
