Relative expression of biophysically relevant transcripts coding for receptors, Na+, K+, and Ca++ channels, ion pumps, and Ca++-binding proteins. Expression levels are expressed relative to other transcripts in the library (right axis) and relative to the Grid2 transcript coding for the PC synapse-specific glutamate receptor, ionotropic delta 2. Gene names are color-coded according to the differential expression between cytoplasm and ER fractions.
