3. Enation

4. Epidermal growth factor (EGF)
A polypeptide growth factor that stimulates the growth of epithelial cells. It was discovered by Stanley Cohen, and a part of the gene which codes for the receptor on the cells that heed its signals is extremely similar to the erb-b oncogene (proto- cancer gene).

5. Erb-b
One of two oncogene s (proto- cancer gene ) found in the avian erythroblastosis retrovirus (a retrovirus which affects red blood cell formation in birds). It is incredibly similar to a gene which codes for the receptor protein that recognizes signals from the epidermal growth factor (EFG) for the cell .
