Recombinant Human KRAS(G12C, His, E.coli)  别名：Ki-Ras; c-K-ras; KRAS2; 重组人 KRAS 蛋白 G12C（ His, E.coli)

Recombinant Human GTPase Kras is produced by E.coli expression system and the target gene encoding Thr2-Cys185(Gly12Cys) is expressed with a 6His tag at the N-terminus. The K-Ras protein is a GTPase, which means it converts a molecule called GTP into another molecule called GDP. In this way the K-Ras protein acts like a switch that is turned on and off by the GTP and GDP molecules. K-Ras functions as a molecular on/off switch. Ras proteins bind GDP/GTP and possess intrinsic GTPase activity. Plays an important role in the regulation of cell proliferation. Plays a role in promoting oncogenic events by inducing transcriptional silencing of tumor suppressor genes (TSGs) in colorectal cancer (CRC) cells in a ZNF304-dependent manner. Besides essential function in normal tissue signaling, the mutation of a K-Ras gene is an essential step in the development of many cancers. Several germline K-Ras mutations have been found to be associated with Noonan syndrome and cardio-facio-cutaneous syndrome.
