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. These layers work in concert to facilitate the cilia-mediated transport of mucus for the capture and clearance of inhaled materials to prevent lung damage. The mechanisms by which mucin biopolymers protect the lung from injury have been HUGO Gene Nomenclature Committee (HGNC) gene group index page listing all the HGNC gene groups. The intestinal mucus proteome is ∼ 50 proteins with a few that are very abundant. The major component is the MUC2 mucin, the function of which has been determined in recent years. However, the biology. A lubricant mucin in saliva is made up of .
One research group attempting to identify the specifics regarding mucins is the Mucin Biology Group at the University of Gothenburg in Sweden. There are currently more than 20 human mucin genes that have been identified. The genes encoding mucin proteins are generally designated MUC (MUC1-MUC20) and have homologs in many species other than humans. membrane mucins in mucosal innate immunity. Membrane mucins cover the brush border membrane of enterocytes throughout the intestine, but their function remains undefined.
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.
2021-01-19 · Analysis performed using supported molecular matrix electrophoresis, a methodology developed for mucin analysis, and knockout mice without the polycomb group protein Bmi-1 revealed that Bmi-1 regulates mucin levels in the submandibular gland by suppressing the expression of the mucin Smgc gene, and that Bmi-1 also regulates mucin O-glycosylation via suppression of the glycosyltransferase Gcnt3

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.
Mucins are a family of high molecular weight, heavily glycosylatedproteins (glycoconjugates) produced by 27 Feb 2021 Mucin in the largest biology dictionary online. Free learning resources for students covering all major areas of biology. We are the Max Planck Institute of Molecular Cell Biology and Genetics (MPI- CBG). We do pioneering basic research.
Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. 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.

Our laboratory works in three areas of mucus biology 2021-01-19 Gastrointestinal mucins produced by goblet cells comprise the main structural components of the mucus layer. Mucins play a critical role in the maintenance of mucosal homeostasis and are responsible for the differential effector and regulatory responses against a plethora of microorganisms, including commensals and pathogens. Gel-forming mucin that is thought to contribute to the lubricating and viscoelastic properties of whole saliva and cervical mucus.
Each mucin has a unique and characteristic sequence of tandemly repeating amino acids rich in serine and/or threonine. The tandem repeat domain is the primary region for O -linked glycosylation of the molecule. Our research group is part of Mucin Biology Groups at the University of Gothenburg. We are one of few research labs in the world who study the function and regulation of membrane mucins in defending our gastrointestinal tract.

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.
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. Mucins are a family of high molecular weight, heavily glycosylated proteins produced by epithelial tissues in most animals.

H.pylori colonize by its adhesion via BabA and SabA adhesins to the blood group antigens Le B and Sialyl Le X present on gastric mucin MUC5AC . The reduced MUC5AC expression might be associated with H.pylori mediated gastric carcinogenesis and the progression to GC ( 80 ).
Can act both as an adhesion and an anti-adhesion protein.
