Tn antigen (Tn), a single N-acetylgalactosamine (GalNAc) monosaccharide attached to protein Ser and Thr residues, is found on most solid tumors yet rarely detected in adult tissues: featuring it one of the most distinctive signatures of cancers. Although it is prevalent in cancers, Tn-glycosylation ...

An early-differentiated CD8+ memory T cell subset with stem cell-like properties (TSCM) can be identified within the naïve-like T cell population by the expression of CD95/Fas. Based on experiments including exon- and gene-level expression analysis, we provide evidence that this subset of antigen-sp...

Proteins modified with O-GlcNAc and O-GalNAc (the Tn antigen) play critically important roles in many physiological and pathological processes. Comprehensive and site-specific analysis of proteins modified with O-GlcNAc and the Tn antigen advances our understanding of glycoprotein functions and cell...

We employed the newly available IMPa O-glycoprotease from Pseudomonas aeruginosa for O-glycoproteomics analysis of cultured cells and tissues. The glycopeptides were extracted, purified, and conjugated to a solid support before an enzymatic cleavage by IMPa. O-glycopeptides were analyzed by EThcD, w...
