The DNA replication-related element binding factor (DREF) has been suggested as being involved in regulation of DNA replication- and proliferation-related genes in Drosophila. Recently, by searching the Drosophila genome database, we also found DRE-like sequences in the 5'-flanking regions of many genes with other functions. In addition, immunostaining of(More)
Mammalian Elongin C is a 112-amino acid protein that binds to the von Hippel-Lindau (VHL) tumor suppressor and to Elongin A, the transcriptionally active subunit of the RNA polymerase II elongation factor, SIII. It is conserved in eukaryotic cells, as homologs have been identified in Saccharomyces cerevisiae, Drosophila melanogaster and Caenorhabditis(More)
The gene promoter of Drosophila proliferating cell nuclear antigen (dPCNA) contains several transcriptional regulatory elements, such as upstream regulatory element (URE), DNA replication-related element (DRE, 5'-TATCGATA), and E2F recognition sites. In the present study, a yeast one-hybrid screen using three tandem repeats of DRE in dPCNA promoter as the(More)
A DNA replication-related element (DRE)-binding factor (DREF) has been revealed to be an important transcription factor for activating promoters of cell proliferation and differentiation related genes. The amino acid sequences of DREF are conserved in evolutionary separate Drosophila species, Drosophila melanogaster (Dm) and Drosophila virilis (Dv) in three(More)
Here we show that Armadillo and Pangolin (dTCF), downstream effectors of the Wingless (Wg) signal transduction pathway, activate transcription of the important DNA replication-related genes encoding Drosophila proliferating cell nuclear antigen (PCNA) and DNA replication-related element-binding factor (DREF). By transient luciferase expression assays and(More)
