Abstract
It is increasingly clear that the three RAS genes, N-. H- and K-RAS, encode 21 kDa proteins which act as intracellular switches, play a signal transduction pathway in controlling cell growth and differentiation. The three genes are highly homologous, yet recent evidence suggests they may have distinct functions in different cell types and have a central role in many human diseases. This article reviews briefly the regulation of signaling mechanisms.
