There is sufficient evidence that the A-MuL V protein is a tyrosine-specific protein kinase. There are methods for detecting this kinase activity and this kinase has been expressed in E. coli. Because the information coding for the tyrosine-specific protein kinase is present in normal mouse cells, such an enzyme must have a normal physiologic function. The elucidation of this physiologic function and the understanding of the role of this enzyme activity in neoplastic transformation is the challenge of the future.
有充分证据表明A-MuLV蛋白是一种酪氨酸特异性蛋白激酶。存在检测这种激酶活性的方法,并且这种激酶已在大肠杆菌中表达。由于编码酪氨酸特异性蛋白激酶的信息存在于正常小鼠细胞中,因此这种酶必定具有正常的生理功能。阐明这种生理功能以及了解这种酶活性在肿瘤转化中的作用是未来的挑战。
