The normal cellular counterpas of oncogenes are impoant for the following functions, except:
Promotion of cell cycle progression
Inhibition of apoptosis
Promotion of DNA repair
Promotion of nuclear transcription
Oncogenes may function by inactivation of DNA repair genes, but not by promotion of DNA repair. Ref: Robbin's Illustrated Pathology, 7th Edition, Pages 293, 295; Oncogenes By Geoffrey M. Cooper, 1995, Preview.
