Species | Human |
Protein Source | E. coli |
Expression cDNA Clone or AA Sequence |
Met1-Lys169
|
Tag | N-6His |
Buffer | Lyophilized from a 0.2 um filtered solution of PBS, pH7.4. |
Note | Recombinant Human GTPase Kras4B is produced by our E.coli expression system and the target gene encoding Met1-Lys169 is expressed with a 6His tag at the N-terminus. |
Storage | Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months. |
Stability | 12 months from date of despatch |

Synonyms | Ki-Ras; c-K-ras; KRAS2; RASK2; CFC2 |
Summary | K-Ras belongs to the small GTPase superfamily, Ras family. As other members of the Ras family, K-Ras is a GTPase and is an early player in many signal transduction pathways. It is usually tethered to cell membranes because of the presence of an isoprenyl group on its C-terminus. 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[4] and cardio-facio-cutaneous syndrome. Somatic K-Ras mutations are found at high rates in Leukemias, colon cancer, pancreatic cancer and lung cancer. |
