KRAS Protein, Human, Recombinant (G12S, GST)

KRAS Protein, Human, Recombinant (G12S, GST) is expressed in E. coli expression system with GST tag. The accession number is P01116.

生物活性	A Homogeneous Time-Resolved Fluorescence (HTRF) based system was established for the protein-protein interaction between KRAS-G12S and its interacting protein SOS1. The positive compound, SOS1 inhibitor BI3406, exhibited an inhibitory activity (IC50) of approximately 18 nM, consistent with reported activities in the literature.

研究背景	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.
