Aberrant glycosylation occurs in essentially all types of cancers and results in increased sialylation. Thus, when the mucin MUC1 is expressed on cancer cells, it is decorated by multiple short, sialylated O-linked glycans (MUC1-ST). Abstract. Mucin-type O-linked glycosylation is a fundamental post-translational modification that is involved in a variety of important biological processes. However, the lack of chemical tools to study mucin-type O-linked glycosylation has hindered our molecular understanding of O-linked glycans in many biological contexts. As noted above, the defining feature of mucin O-linked glycosylation compared to other types of glycosylation is the initial addition of GalNAc to Ser/Thr residues of protein substrates. 37 One useful group of metabolic inhibitors of mucin O-linked glycosylation utilizes GalNAc analogs as decoy primers that suppress elaboration of O-linked glycans.

mucin: [ mu´sin ] a mucopolysaccharide or glycoprotein that is the chief constituent of mucus. Siglec-9 is a sialic-acid-binding lectin expressed predominantly on myeloid cells. Aberrant glycosylation occurs in essentially all types of cancers and results in increased sialylation. Thus, when the mucin MUC1 is expressed on cancer cells, it is decorated by multiple short, sialylated O-linked glycans (MUC1-ST). Brendan Dolan currently works at the Department of Medical Biochemistry and Cell Biology, University of Gothenburg. Brendan is a postdoctoral researcher in the Mucin Biology Group All mucins are highly O-glycosylated by variable glycans depending on species, histoblood group and organ.

Download as PDF. There are two main groups of mucins; the classical gel-forming polymeric mucins (MUC2, MUC5AC, MUC5B, and MUC6) and a more heterogeneous group of monomeric transmembrane mucins (MUC1, MUC3, MUC4, MUC12, MUC13, MUC15, MUC16, MUC17, MUC20, and MUC21).

membrane mucins in mucosal innate immunity. Membrane mucins cover the brush border membrane of enterocytes throughout the intestine, but their function remains undefined. Our aim is to elucidate the function of membrane mucins in intestinal barriers and to determine how we can harness the function of membrane mucins in order to combat diseases such as Inflammatory bowel disease (IBD) and endemic intestinal infections.

Short name: MUC-2 Protein family/group databases. MEROPS National Institutes of Health The European Molecular Biology Laboratory State Mucin is released from specialized cells known as goblet cells through a process of vesicle exocytosis. In this process, small vesicles densely packed with mucin fuse with the cell's membrane and open into the extracellular space. The mucin expands from the vesicle into this space at a very rapid rate.

The major component is the MUC2 mucin, the function of which has been determined in recent years. However, the The two major proteins present in saliva are amylase and mucin. It is a mucopolysaccharide or glycoprotein that is the chief constituent of mucus. It is present in most glands that secrete mucus and is the lubricant that protects body surfaces from friction or erosion.

These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists. Mucins are commonly associated with pancreatic ductal adenocarcinoma (PDAC) that is a deadly disease because of the lack of early diagnosis and efficient therapies. There are 22 mucin genes encoding large O-glycoproteins divided into two major subgroups: membrane-bound and secreted mucins. We investigated mucin expression and their impact on patient survival in the PDAC dataset … The most common O-linked glycans are the mucin-type glycans, which contain an initial GalNAc residue. There are eight mucin-type core structures (see Figure 1). Even with common mucin-type cores, O-linked glycans tend to be very heterogeneous, and there are other structures possible, in addition to several sialylated core structures. In the lung, the airway epithelium produces secreted and tethered mucin biopolymers to form a mucus hydrogel layer and a surface-attached polymer brush layer.
