Abstract

After a cell goes through mitosis or meiosis, a process called cytokinesis takes place. During cytokinesis the cytoplasm of the cell is divided between two daughter cells. Cytokinesis is a vital cellular process as it physically splits the components of the cell into two daughter cells. Budding yeast, like other eukaryotic cells, divides the cell membrane using an actomyosin contractile ring. In yeast cells, a protein known as IQG1 is required for the contraction of the actomyosin ring that divides the daughter cells. Phosphorylation mutations of IQG1 cause the actomyosin ring to form incorrectly. With IQG1 being essential to actomyosin, formation mutations cause defects in cytokinesis of yeast cells. My research will focus on the study of different phosphorylation mutations of IQG1 and their effects on binding to actin.
