J. Michael Bishop and Harold Varmus first identified these genes in chicken retroviruses; the first to be isolated is called src ("S R C"). "Anti-" examples of these include BRCA1 and p53, while normal forms of them often code for kinase enzymes involved in the signal transduction pathways of the cell cycle. They are grouped in families like myc (MIHK), mas ("mass"), and ras (RAAS), the latter being active in twenty-five percent of human carcinomas. Arising from amplification or mutations in their proto- forms, identify these genes that transform normal cells into tumor cells.
