- Ras GTPase - Wikipedia
Ras, from " Rat sarcoma virus ", is a family of related proteins that are expressed in all animal cell lineages and organs All Ras protein family members belong to a class of protein called small GTPase, and are involved in transmitting signals within cells (cellular signal transduction)

- Ras蛋白_百度百科
Ras的活性受两个蛋白的控制，一个是鸟苷交换因子 (guanine nucleotide exchange factor, GEF)，它的作用是促使GDP从Ras蛋白上释放出来，取而代之的是 GTP，从而将Ras激活，GEF的活性受 生长因子 及其受体的影响 [2]。 例如，在 表皮生长因子 （EGF） 信号通路 中，活化的受体通过接头蛋白Grb2招募并激活SOS1（一种关键的GEF），进而激活Ras。 在胰岛素信号通路中，SOS1则通过 胰岛素受体底物 Shc 被招募并激活 [11]。
- RAS信号途径_百度百科
RAS信号途径是细胞内一条关键的信号传导通路，其核心是RAS蛋白（属于小GTP酶家族），作为分子开关在GTP结合的活性态与GDP结合的失活态之间转换 [5]。 该途径主要包括KRAS、NRAS、HRAS三个成员 [2] [4]。 其活性受 鸟嘌呤核苷酸交换因子 （GEF，如SOS1）和 GTP酶激活蛋白 （GAP，如NF1）精密调控 [5]。 该通路在正常生理中调控细胞增殖、分化、存活与迁移等基本过程 [5] [8]。 RAS基因是人类癌症中最常见的突变基因之一，约30%的肿瘤携带RAS变异。 KRAS突变尤为常见，存在于约90%的 胰腺癌 、约50%的 结肠癌 和约25%的 肺腺癌 中。 这些突变（如G12、G13、Q61）导致RAS蛋白持续激活，驱动肿瘤发生 [4-5]。
