KRAS Protein, Human, Recombinant, AviTag
Human KRAS protein is a small guanosine triphosphatase (GTPase) that is the component of the mitogen activated protein kinase (MAPK) signaling pathway. High occurrences of KRAS mutations in some types of cancers make KRAS one of the most important targets in oncology for drug development.
