The DRE sequence TATCGATA, a putative promoter-activating element for Drosophila melanogaster cell-proliferation-related genes.

Abstract:

We have confirmed that the DNA replication-related element (DRE) consisting of an 8-bp palindrome, TATCGATA, and not neighboring sequences, are responsible for activating promoters of the Drosophila melanogaster (Dm) PCNA (proliferating cell nuclear antigen)- and DNA polymerase alpha-encoding genes in both cultured cell and transgenic fly systems. We have so far found 153 copies of DRE in the Dm gene database. 73 of them are concentrated within the 600-bp upstream regions from the transcription start points of 61 genes. Interestingly, many of these genes are involved in either DNA replication, transcription, translation, signal transduction, cell cycle or other putative regulatory functions, and are possibly related to cell proliferation. It seems likely that DRE is an element common to the regulation of cell-proliferation-related genes, although their expression patterns may be different depending on which of regulatory elements other than the DRE are combined.
