Mucin-type O-glycans and their roles in intestinal homeostasis.
Mucin-type O-glycans are the primary constituents of mucins that are expressed on various mucosal sites of the body, especially the bacteria-laden intestinal tract. Mucins are the main components of mucus, which is secreted by goblet cells and forms a protective homeostatic barrier between the resident microbiota and the underlying immune cells in the colon. However, the specific role of mucin-...
متن کاملPOMGNT1 Is Glycosylated by Mucin-Type O-Glycans.
Protein O-linked mannose β1,2-N-acetylglucosaminyltransferase 1 (POMGNT1) is a Golgi glycosyltransferase that catalyzes the formation of the N-acetylglucosamine (GlcNAc) β1→2Man linkage of O-mannosyl glycan. POMGNT1 is not modified by N-glycans because there are no potential N-glycosylation sites; however, it is not clear whether POMGNT1 is modified by O-glycans. To determine whether POMGNT1 is...
متن کاملMucin-type O-glycans in human colon and breast cancer: glycodynamics and functions.
The glycoproteins of tumour cells are often abnormal, both in structure and in quantity. In particular, the mucin-type O-glycans have several cancer-associated structures, including the T and Tn antigens, and certain Lewis antigens. These structural changes can alter the function of the cell, and its antigenic and adhesive properties, as well as its potential to invade and metastasize. Cancer-a...
متن کاملGlyco-engineering for the production of recombinant IgA1 with distinct mucin-type O-glycans in plants
IgA nephropathy (IgAN) is a common autoimmune disease that is characterized by formation and deposition of IgA1-containing immune complexes frequently leading to end-stage kidney disease. The IgA1 in these immune complexes carries aberrantly glycosylated O-glycans. In circulating IgA1 these galactose-deficient mucin-type O-glycans are bound by autoantibodies and thus, contribute to immune compl...
متن کاملAn improved lectin-based method for the detection of mucin-type O-glycans in biological samples.
Mucins and mucin-type glycoproteins, collectively referred to as mucin-type O-glycans, are implicated in many important biological functions and pathological conditions, including malignancy. Presently, there is no reliable method to measure the total mucin-type O-glycans of a sample, which may contain one or more of these macromolecules of unknown structures. We report the development of an im...
