HFP ACTIVATES PROTEOLYSIS OF POSITIVE CELL CYCLE REGULATORS TO INHIBIT CELL CYCLE PROGRESSION IN DROSOPHILA

Grant number: 350267

Abstract

Cell proliferation is essential for animal development and tissue regeneration. In order to proliferate, cells must double their DNA contents and segregate their chromosomes precisely into daughter cells. Collectively this series of events is referred to as the Cell Cycle. The cell cycle must be carefully regulated since inappropriate proliferation can cause developmental abnormalities and tumour formation in multicellular animals. Proliferation is regulated by a balanced set of interactions between two group of proteins, cell cycle activators and cell cycle inhibitors. Aberrations in cell cycle inhibitor proteins will cause excessive cell proliferation, the first step in the multi-step proc..
