Biochemical and Physiological Mechanisms
K-Ras belongs to the small GTPase superfamily, Ras family. Like 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 isopreny
Bioactivity
