when the expression of v-myb ( the oncogene of avian myeloblastosis virus ) was examined in cells of these three differentiation stages , it was found that the protein encoded by v-myb ( p45v-myb ) continued to be synthesized in similar quantities and showed no obvious alteration ( assessed by partial proteolytic digestion and two-dimensional gel electrophoresis ) during differentiation .
