This makes the intestinal main mucin MUC2 non-degradable by the host digestive system but Mucin biology is dynamic and the processes of degradation and turnover are well integrated with biosynthesis to maintain a continuous mucosal protection against all external aggressive forces. Interaction of mucins with microflora plays an important role in normal function. 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). Abstract. Mucin-type O-linked glycosylation is a fundamental post-translational modification that is involved in a variety of important biological processes.

Here we provide databases of mucin genes, transcripts,protein sequences and functional domains. The databases are frompublished mucins and novel mucins found by bioinformatic mining of theavailable genomes. Mucins are large, highly glycosylated molecules having typical mucin domains, where the oligosaccharides are linked via N-acetylgalactosamine to the amino acids threonine and serine. Mucins are forming the gel-like properties of mucus.

Mucin glycopattern from bronchoalveolar lavage fluid (BALF) from each group can be easily correlated to the pro/anti‐inflammatory cytokines by proteomic analysis to determine the magnitude of inflammation (cytokine storm), the hallmark of COVID‐19 deaths.

Gastric mucin protects the stomach from an attack of acids. it is mainly produced by goblet cells, apical cells of the conjunctiva and cornea and the lacrimal gland. It is present in saliva and bile and in salivary glands, in the skin, connective, tissues, tendon, and 2001-12-01 2011-05-03 Mucin polymers coat all the wet surfaces in the human body, providing a selective barrier that allows nutrients and information in while keeping pathogens out. 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.

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. Mucins' key characteristic is their ability to form gels; therefore they are a key component in most gel-like secretions, serving functions from lubrication to cell signalling to forming chemical barriers. They often take an inhibitory role.

Plays an important role in the cytoprotection of epithelial surfaces and are used as tumor markers in a variety of cancers. 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.

Interaction of mucins with microflora plays an important role in normal function. There is growing recognition that mucus and mucin biology have a considerable impact on respiratory health, and subsequent global morbidity and mortality. Mucins play a critical role in chronic lung disease, not only by providing a physical barrier and clearing pathogens, but also in immune homeostasis. The aim of this review is to familiarise the reader with the role of mucins in both lung health and disease, with particular focus on function in immunity, infection and inflammation.

TIM-1 (T-cell immunoglobulin and mucin domain1), also known as KIM-1 (kidney injury molecule 1), is a transmembrane protein expressed on various immune cells and epithelial cells, involved in the modulation of the inflammatory and immune responses. 1 It also acts as a scavenger receptor for oxidized LDL (low-density lipoprotein) and phosphatidylserine, participating in the phagocytosis of Mucus plays a pivotal role in protecting the respiratory tract against microbial infections. It acts as a primary contact site to entrap microbes and facilitates their removal from the respiratory tract via the coordinated beating of motile cilia. The major components of airway mucus are heavily O -glycosylated mucin glycoproteins, divided into gel-forming mucins and transmembrane mucins.
