5. Proto-oncogenes are genes that are normally active during development to promote cell division. These genes are important but highly regulated. When they are activated inappropriately they become oncogene and promote the growth of cells unchecked resulting in tumors. Their typical cellular functions are as intracellular signal transducers, like ras or beta-catenine, or as transcription factors, like Jun and Myc. Intracellular signal transducers ...
