Spot number refers to Figure 1.
bAccession number from IPI (International Protein Index) database of matched proteins.
cPI refers to isoelectric point.
dPercent of number of observed amino acids in sequence length (%).
e” means downregulation, and “↑” means upregulation. Superscripts such as “1h” represented the time point when the fold change reached maximum. The fold change in the table was the maximum change among the different time points.
fCombined scores of all observed mass spectra matched to amino acid sequences used for protein identification.
