Ras is activated early in the signal transduction pathway. It is typically activated by receptor tyrosine kinases, which initiate the pathway by catalyzing the phosphorylation of downstream components. Ras then activates a cascade of kinases, including the MAP kinase pathway, which ultimately leads to changes in gene expression and cellular responses.
