Ras protein Notes:
Ras is a family of related proteins which is expressed in all animal cell lineages and organs. These ras proteins are basically a class of proteins called small GTPase, and are involved in transmitting signals within cells. Certain mutations in the ras gene can lead to production of a hyperactive Ras protein that triggers the kinase cascade even in the. absence of growth factor, resulting in increased cell division and ultimately can lead to cancer.
