PEG mass tags allow visualization of OGlcNAc stoichiometry. 5K PEG mass tags were affixed to OGlcNAc groups on proteins from control or activated T cells via enzy matic labeling with azide and copperfree click chemistry. Proteins were then analyzed for shifts in electrophoretic mobility by immunoblot. For the unlabeled control samples, either the azide (Az) or PEG (PEG) reagent was omitted during the labeling procedure. Note that HCFC1 appears as multiple bands because the protein is expressed as a single polypeptide that under goes proteolytic processing. UBAP2L appears as two bands in the unlabeled control samples due to alternative splicing. Table S1. Details of 133 higher confidence and 81 lower confidence O-GlcNAc glycoproteins1.

1. Proteins are classified as higher confidence hits (at least 8 total sequenced peptides, at least 2 unique sequenced peptides, a chi-square p-value of less than 0.05, and at least 90% of total peptides originating from the labeled conditions) or lower confidence hits (at least 4 total sequenced peptides, at least 2 unique sequenced peptides, and at least 90% of total peptides originating from the labeled conditions). Proteins are listed by their UniProt ID, symbol, and percent of total spectral counts in the labeled conditions (specificity). To provide an objective measure of whether the protein is significantly enriched in the labeled conditions, we performed chi-square tests for the higher confidence proteins to assess whether the observed total spectral counts from the labeled and unlabeled conditions significantly differed from the expected values (2/3 of total counts from labeled conditions and 1/3 from unlabeled).
