Notch is a developmental signalling receptor with widespread and important roles in metazoan development and also in adult stem cell regulation. The fundamental importance of Notch to the healthy adult organism is illustrated by the impact Notch signal decline has on aging skeletal muscle repair13 and the important roles Notch has on the homeostasis of the intestine where Notch regulates the balance between proliferation and differentiation. Numerous associations have been found between loss and gain of function human Notch mutations and diseases including dementia, heart disease and cancer. We have found in Drosophila model organism that Notch can be activated by several different mechanisms both ligand-dependent or independent. These involve the activity of ubiquitin ligase regulators of Notch called Deltex and Su(dx) which target Notch to different trafficking pathways. Human homologues of these regulatory proteins are known but to date there is little information concerning how they function to regulate human Notch. This project will compare the regulation of Drosophila and human Notch through endocytic pathway regulation and identify whether different cancer-associated Notch mutations activate one pathway preferentially, thus laying the basis for future potential targeted therapeutic strategies for Notch-dependent cancers
