| Specificity / Sensitivity | Ras Antibody detects endogenous levels of total K-Ras, H-Ras, and N-Ras. This antibody may also cross-react with R-Ras and M-Ras. |
| Source / Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues close to the amino-terminus of human K-Ras. Antibodies are purified by protein A and peptide affinity chromatography. Western Blotting
Western blot analysis of extracts from HT-29, PAE, NIH-3T3, AR42J, PC12 and C6 cell lysates,using Ras Antibody. |
| Background | The 21 kDa guanine-nucleotide binding proteins (K-Ras, H-Ras and N-Ras) cycle between active (GTP-bound) and inactive (GDP-bound) forms (1). Receptor tyrosine kinases and G-protein-coupled receptors activate Ras, which then stimulates the Raf-MEK-MAPK pathway (2-4). GTPase-activating proteins (GAP) normally facilitate the inactivation of Ras. However, in 30% of human tumors, point mutations in Ras prevent the GAP-mediated inhibition of this pathway (5). The most common oncogenic Ras mutation found in tumors is Gly12 to Asp (G12D), which prevents Ras inactivation, possibly by increasing the overall rigidity of the protein (5,6).

文献和实验Ras是大鼠肉瘤(rat sarcoma,Ras)的英文缩写。Ras蛋白是原癌基因 c—ras的表达产物，相对分子质量为21kDa，属单体 GTP结合蛋白，具有弱的 GTP酶活性。Ras蛋白的活性状态对细胞的生长、分化、细胞骨架、蛋白质运输和分泌等都具有影响，其活性则是通过与GTP或GDP的结合进行调节。 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
Mathematical Investigation of How Oncogenic Ras Mutants Promote Ras Signaling
We have used a mathematical model of the Ras signaling network to link observable biochemical properties with cellular levels of RasGTP. Although there is abundant data characterizing Ras biochemistry, attributing specific changes
PNAS：RAS 抑制剂又添一员，新型蛋白模拟物或为癌症治疗
导读RAS 是肿瘤患者中最常见的致癌基因之一，目前包括 KRAS、NRAS 以及 HRAS 三种亚型。其中，NRAS 突变多见于黑色素瘤和急性髓系白血病，HRAS 突变多见于膀胱癌和头颈癌，而 KRAS 突变比其他两种更常见，最常发生在肺癌、胰腺癌以及结直肠癌。由于在癌症中的 Ras 蛋白经常发生突变，因此 Ras 突变成为了科学家们着力攻克的热点。RAS 曾被医学界称为「不可成药靶点」，科学家们在研究有效的 RAS 抑制剂方面已经摸索尝试了 30 余年，直至近几年才获得了重大进展。当前已经
