Abstract
E2F has been implicated in growth control because of its association with the retinoblastoma protein and the presence of E2F binding sites in the promoters of several growth-regulated genes. Proteins that bind to an E2F site have been cloned from human and mouse cells. However, these two proteins (human E2F1 and mouse DP-1) are quite different in sequence. We have now cloned a mouse cDNA encoding a protein 86% identical to the human E2F1 protein. The mouse E2F1 cDNA encodes a 430-amino-acid protein with a predicted molecular weight of 46,322 and detects mRNAs of 2.7 and 2.2 kb. Using primers complementary to sequences in the mouse E2F1 3' untranslated region, we mapped the mouse E2F1 gene to chromosome 2, near the Agouti and c-src loci. To understand the role of the different E2F family members in the growth of mouse NIH 3T3 cells, we examined the levels of E2F1 and DP-1 mRNAs in different stages of the cell cycle. Since the levels of E2F1 but not DP-1 mRNA correlated with changes in transcription from the dhfr promoter, we examined whether E2F1 could activate various growth-regulated promoters. We found that E2F1 could activate some (dhfr, thymidine kinase, and DNA polymerase alpha) but not all (thymidylate synthase, cad, and c-myc) of these promoters. On the basis of changes in levels of E2F1 and its ability to transactivate growth-regulated promoters, we propose that E2F1 may mediate growth factor-initiated signal transduction.
