Quantitative sandwich ELISA for measuring Human V-Ki-Ras2 Kirsten Rat Sarcoma Viral Oncogene Homolog (KRAS) in samples from cell culture supernatants, serum, whole blood, plasma and other biological fluids.
Like other members of the Ras family, the KRAS protein is a GTPase and is an early player in many signal transduction pathways. KRAS is usually tethered to cell membranes because of the presence of an isoprenyl group on its C-terminus. When mutated, KRAS is a oncogene. The protein product of the normal KRAS gene performs an essential function in normal tissue signaling, and the mutation of a KRAS gene is an essential step in the development of many cancers.KRAS acts as a molecular on/off switch, once it is turned on it recruits and activates proteins necessary for the propagation of growth factor and other receptors' signal, such as c-Raf and PI 3-kinase. KRAS binds to GTP in the active state and possesses an intrinsic enzymatic activity which cleaves the terminal phosphate of the nucleotide converting it to GDP.
