Complementary DNA clones of a putative transforming gene were isolated from NIH 3T3 cells transformed with human Ewing sarcoma DNA. The gene was termed B-raf because it is related to but distinct from c-raf and A-raf. It appears that substitution in the amino-terminal portion of the normal B-raf protein confers transforming activity to the gene.
