Minimum protein identification confidence: 99%, minimum peptide identification confidence: 95% requiring at least two peptides per protein. G-test or Student's t-test was accepted at p < 0.05 with at least a 1.5-fold change.
Student's t-test for total MS2 TIC, unless significant enrichment was detected only with spectral counting for which the G-test is reported.
Spectral counts, if significant enrichment detected only with spectral counting—otherwise, total MS2 TIC. Total MS2 TIC and spectral counts are given as average ± standard error.
Identification made by SEQUEST alone.
Significant enrichment detected only using MS2 TIC criteria.
Significant enrichment detected only with spectral counting.
Significant enrichment detected with both spectral counting and using MS2 TIC criteria.
