癌基因的发现使有关控制正常和性细恶胞增殖的研究进入了新的时代。由于发现癌基因编码的蛋白质包括一种分泌的生长因子、一种生长因子受体的同系物和几种酪氨酸特异的蛋白激酶,使人们更加相信细胞癌基因编码的蛋白质是在正常细胞生长控制的生化过程中必不可少的参与者,并且认为恶性肿瘤的这些过程可能出现了微小的差错。这些酪氨酸特异性激酶催化的反应与一些激活生长因子受体后所催化的反应相 The discovery of oncogenes has led to a new era in the study of the control of the proliferation of normal and malignant cells. Since the oncogene-encoded proteins were found to include a secreted growth factor, a homologue of a growth factor receptor, and several tyrosine-specific protein kinases, it became more convincing that the protein encoded by the cellular oncogene was involved in normal cell growth. An indispensable participant in the controlled biochemical process, and believes that these processes of malignancy may have caused minor errors. The reactions catalyzed by these tyrosine-specific kinases are related to those catalyzed by the activation of growth factor receptors.
