Abstract:In addition to the backbone molecules of proteins and lipids, RNAs have recently been found to be N-glycosylated as well in cell models. Some overlap of N-glycans between RNA and protein exist in terms of monosaccharide composition. Here we report a draft of human tissue N-glycans of glycoRNA covering 12 typical organs as characterized by mass spectrometry-based N-glycomics. RNAs were first prepared, N-glycans were then enzymatically released, hydrophilically enriched, permethylated, analyzed by RPLC-MS/MS, an… Show more
