|Analysis of the function of Drosophila cyclin E isoforms and identification of interactors / Donna Crack.

|Analysis of the expression of Drosophilia cyclin EII through development show that it was present during larval development and oogenesis, implying a role for DmcycEII outside of early embyogenesis. Ectopic expression analyses using full-length DmcycE proteins as well as N- and C-terminal deletions of DmcycEI, revealed that DmcycEII and N-terminal deletions were able to drive all G1 cells within the morphogenetic furrow of the eye imaginal disc into S phase, while a C-terminal deletion of DmcycEI could not. These results show the DmcycEII is more potent than DmcycEI in driving cells into S phase and that the N-terminal region of DmcycEI contains a negative regulatory domean., suggesting that an inhibitor is present in the posterior morphogenetic furrow that binds to DmcycEI N-terminus and inhibits DmcycEI function. To identify the DmcycEI specific inhibitor, genetic interaction and yeast-2 hybrid screens were undertaken, and an enhancer CG7394, encoding a MAGUK homologue was identified for further study.
