The Summer Undergraduate Research Fellowship (SURF) Symposium
Saccharomyces cerevisiae Dbf4(Dumbbell former 4) and Cdc7(Cell Division Cycle 7) form a complex that phosphorylates Mcm2 (Minichromosome maintenance 2) to initiate DNA replication. Cdc7 is a target for cancer research because there is a Cdc7 ortholog in humans that is necessary for DNA replication and cell survival. Our goal is to characterise a putative Cdc7 homolog in Drosophila melanogaster (dCdc7). We have previously shown that expression of the known Drosophila Dbf4 ortholog, Chiffon, and dCdc7 can rescue yeast cells deficient in active Cdc7. Our hypothesis is that the dCdc7 is activated by Chiffon to phosphorylate MCM2. To test this hypothesis, …
