Glycan types
WebGlycan-Protein interactions represent a class of biomolecular interactions that occur between free or protein-bound glycans and their cognate binding partners. Intramolecular glycan-protein (protein-glycan) interactions occur between glycans and proteins that they are covalently attached to. ... Indeed, there are no known types of cancer that ...

WebGlycan nomenclature is the systematic naming of glycans, which are carbohydrate-based polymers made by all living organisms.In general glycans can be represented in: (i) text formats: These includes commonly used CarbBank, IUPAC name, and several other types and (ii) symbol formats: These are consisting of Symbol Nomenclature For Glycans and … WebIn general, alterations affecting all discussed glycan types are increased sialylation, fucosylation as well as (sialyl) Lewis-type antigens and type-2 chain glycans. As a consequence, interactions with glycan-binding proteins can be affected and the biological function and cellular consequences of the altered glycosylation with regard to ...
WebThe composition of the intestinal mucus is regulated by complex O-glycan-specific interactions among the gut microbiota, RV and the host. In this review, we highlight O-glycan-mediated interactions within the intestinal lumen prior to RV attachment to IECs. A better understanding of the role of mucus is essential for the development of ... WebDISCOVERY OF NOVEL TYPES OF GLYCOSYLATION. In glycoproteins, the linkage between the first sugar of a glycan and the protein defines its glycosylation class (Chapter 1, Figure 1.7) including the common …
WebO -Glycans are primary components of the intestinal mucins that form the mucus gel layer overlying the gut epithelium. Core 3-derived O -glycans, which are one of the major types of O -glycans, are primarily expressed in colon. To investigate the biological function of core 3-derived O -glycans, we engineered mice lacking core 3 β1,3- N ...
