Abstract
Full-length and N-terminal deletion mutants of human c-raf-1 cDNA were cloned into Escherichia coli expression plasmids. Bacterially expressed c-raf proteins were purified by anion-exchange, gel filtration, and affinity chromatography. Microinjection of mutant c-raf proteins into G0-arrested NIH 3T3 cells induced DNA synthesis and morphological transformation, whereas microinjection of full-length c-raf had no effect. The amino terminus of the raf protein has an important negative regulatory influence; alteration of this region resulted in increased kinase activity and oncogenicity.Entities:
