Data derived from published quantitative proteomic methods. The abundance of BiP/GRP78 in each dataset was set to 100 and the expression values of the other proteins were normalized to it.
3T3 proteomic data from [108].
D4-positive dendritic cells, peak intensity counts reported in [231].
eLa cell and Caco2 cell proteomics from [232], using peptide spectral counts. Similar results were reported by [233], based on SILAC quantitation.
Values from [234] and are based on purification of proteins.
