WebJan 1, 2024 · GI mucin-producing cells tend to have concentrated, apical mucin cups (foveolar epithelium or goblet cells) as opposed to the more diffuse, cytoplasmic mucin content of MCN. When separating MCN from other non-mucinous cysts, the quality and quantity of the cyst fluid is important. Mucins are secreted as massive aggregates of proteins with molecular masses of roughly 1 to 10 million Da. Within these aggregates, monomers are linked to one another mostly by non- covalent interactions, although intermolecular disulfide bonds may also play a role in this process. Secretion [ edit] See more Mucins are a family of high molecular weight, heavily glycosylated proteins (glycoconjugates) produced by epithelial tissues in most animals. Mucins' key characteristic is their ability to form gels; therefore they are a … See more Human mucins include genes with the HUGO symbol MUC 1 through 22. Of these mucins, the following classes have been defined by … See more The functional classification does not correspond to an exact evolutionary relationship, which is still incomplete and ongoing. Known-related groups include: • The … See more Mucin genes encode mucin monomers that are synthesized as rod-shaped apomucin cores that are post-translationally modified by exceptionally abundant glycosylation. The dense "sugar coating" of mucins gives them considerable water-holding capacity and also makes … See more Mature mammalian mucins are composed of two distinct regions: • The amino- and carboxy-terminal regions are very lightly glycosylated, but rich in cysteines. … See more Mucins have been found to have important functions in defense against bacterial and fungal infections. MUC5B, the predominant mucin in the mouth and female genital tract, … See more Upon stimulation, MARCKS (myristylated alanine-rich C kinase substrate) protein coordinates the secretion of mucin from mucin-filled vesicles within the specialized epithelial cells. Fusion of the vesicles to the plasma membrane causes release of the mucin, which as … See more

WebApr 1, 2005 · Morphologically recognizable mucins are high molecular weight glycoproteins, more than 50% of which consist of O-linked oligosaccharides. 9 Mucins are made up of core proteins coded by mucin... WebThe mucin (MUC) family is a group of highly glycosylated macromolecules that are abundantly expressed in mammalian epithelial cells. MUC proteins contribute to the formation of the mucus barrier and thus have protective functions against infection.
