Crossing the finish line of development: regulated secretion of Dictyostelium proteins.
The genesis of the spore coat of Dictyostelium represents an exquisite example of developmentally regulated protein secretion. The proteins that are destined to be assembled into the extracellular matrix of the spore coat are stored in unique prespore vesicles that are triggered to secrete their contents at terminal differentiation. The regulation of this process is being revealed by the identification of the individual proteins in these vesicles.
