Tight junctions are junctions between cells that are needed for epithelia (e.g. skin, kidney, intestine) to act as barriers. This proposal would determine the structure of proteins in the membrane ofthe tight junction and use this information to elucidate the mechanism by which they function. This work has widespread significance for understanding diseases due to epithelial barrier dysfunction
