信号传导途径新热点：直接效应物模式跨膜信号传导途径的通常模式，是生长因子与受体作用后，使其受体的酪氨酸蛋白激酶活化。活化后的酪氨酸蛋白激酶使磷脂酶ＣＹ活化；或是酪氨酸蛋白激酶使某些蛋白质因子磷酸化，转而引起原癌基因产物ｃ－Ｒａｓ蛋白活化。蛋白激酶Ｃ与...
New Hotspot of Signal Transduction Pathway: The Common Mode of Direct Effector Modes Transmembrane signal transduction is the activation of tyrosine protein kinases at its receptor after the action of growth factors and receptors. Activated tyrosine kinase activates phospholipase CY; or tyrosine protein kinases phosphorylate certain protein factors, which in turn cause activation of the protooncogene c-Ras protein. Protein kinase C and ...
