You have been studying the synapse by electron microscopy and wish to learn more about proteins of the postsynaptic density (PSD). How would you begin
to characterize PSD proteins? How would you pinpoint one protein (protein X) to characterize further? How would you obtain information about this protein
and obtain its cDNA? What would you do with the cDNA to discover its binding proteins? How would you study protein X binding proteins in neuronal cells
and their association with protein X?
