Comparison of the predicted secretion pathways of various secretomes. Four different secretomes were analyzed for their predicted secretion pathways by using three bioinformatics programs, SignalP, SecretomeP and TMHMM. Proteins in each secretome were classified into four categories based on the predicted secretion pathway (classical secretion, nonclassical secretion, integral to membrane, and intracellular). The four secretomes are (i) the proteins annotated as ‘secreted’ in the Uniprot protein database (2746 entries, yellow line), (ii) the secretome identified in the SFM of 12 cell lines (3356 proteins, blue line), (iii) the secretome analyzed after reducing the protein complexity of the SCM (585 proteins, orange line) and (iv) the exosome proteins reported by EVpedia to be cited in more than 100 papers (920 proteins, green line)
