WebDec 1, 2002 · Desmosomes and cadherin-mediated adherens junctions are involved in the adhesion of the two mammary epithelium layers. The luminal cells express larger amounts of E-cadherin than do the myoepithelial cells, whereas P-cadherin is expressed exclusively by the myoepithelial cells. WebFirst, desmosomes, have its connecting proteins (just liek the other types of cell-to-cell connections in animal cells). Their proteins are called cadherins . Cadherins are attached to both cells and they protrude …
WebJun 1, 1996 · cadherin is a cell type-specific heterodimer that associ-ates laterally within the junction. Such tissue-specific pairing may endow desmosomes with distinct adhesive and/or cytoskeletal linking roles. Although the adhesive function of all possible des-mosomal cadherin combinations has not yet been tested, WebThe cadherin (cdh) superfamily of adhesion molecules carry O-linked mannose (O-Man) glycans at highly conserved sites localized to specific β-strands of their extracellular cdh (EC) domains. These O-Man glycans do not appear to be elongated like O-Man glycans found on α-dystroglycan (α-DG), and we recently demonstrated that initiation of cdh ...
