^aDatabase accession numbers according to: Uniprot 2019_02 (559228 sequences; 200905869 residues) database with Homo sapiens (human) (20492 sequences) filter.

^bIdentified homologous proteins.

^cMascot Search Probability Based Mowse Score. Ions score is-10×Log(P), where P is the probability that the observed match is a random event. Protein scores >31 indicate identity or extensive homology (P<0.05).

^dTheoretical mass (Da) of identified proteins. The values were retrieved from the protein database.

^eNumber of matched peptides with Mascot search data (www.matrixscience.com).

^fAmino acid sequence coverage for the identified proteins.

^gExponentially modified protein abundance index of identified protein according to Mascot Search data.
