^aProtein score represents the combined unique ion scores of all observed mass spectra of a protein using Mascot software.

^bTotal ion score represents the combined ion scores of all significant peptides.

^cBest ion score represents the score of the highest matching peptide fragment.

^dCI, confidence interval.
