Rel proteins have been implicated in the differentiation and transformation of lymphoid cells. Despite their significant sequence homology to the Drosophila Dorsal morphogen, a functional role for Rel proteins in early development has yet to be established. Here we show that expression of the v- or c-rel genes in P19 embryonal carcinoma (EC) cells leads to drastic morphological changes accompanied by the expression of several differentiation-specific antigens. In contrast, v-Rel mutants defective for DNA-binding as well as those lacking the F9 cell-specific transcription activation region of v-Rel were equally unable to promote P19 cell differentiation. Our results demonstrate that transcriptional activation by Rel proteins correlates with Rel-induced differentiation of EC cells, and raise the intriguing possibility that Rel proteins may play an important role in early developmental processes.

D011518	Proto-Oncogene Proteins	Products of proto-oncogenes. Normally they do not have oncogenic or transforming properties, but are involved in the regulation or differentiation of cell growth. They often have protein kinase activity.

D002454	Cell Differentiation	Progressive restriction of the developmental potential and increasing specialization of function that leads to the formation of specialized cells, tissues, and organs.	Differentiation, Cell,Cell Differentiations,Differentiations, Cell
D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
