The research focus of our laboratory is to understand the molecular mechanisms controlling interleukin-5 receptor endocytosis and signal termination. Currently, we are investigating how the ubiquitin/proteasome degradation pathway controls the endocytic trafficking of the IL-5 receptor, and how this process contributes to "shutting off" IL-5-mediated signaling. In a related project, we aim to understand the significance of differential compartmentalization of the IL-5R into lipid rafts and clathrin-containing vesicles.
