In cell biology, adherens junctions (or zonula adherens, intermediate junction, or "belt desmosome" [1]) are protein complexes that occur at cell–cell junctions and cell–matrix junctions in epithelial and endothelial tissues, [2] usually more basal than tight junctions. An adherens junction is defined as a cell junction whose cytoplasmic ...
Distal muscular dystrophy, also called distal myopathy, is essentially any muscle disease that preferentially affects the hands and/or feet, a much less common pattern than proximal muscle weakness. Late adult-onset type 1; Late adult-onset type 2a; Late adult-onset type 2b; Early adult-onset type 1; Early adult-onset type 2; Early adult-onset ...
Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions) Gap junctions [5] (communicating junction) Tight junctions (occluding junctions) Invertebrates have several other types of specific junctions, for example septate junctions (a type of occluding junction) [4] or the C. elegans apical junction.
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
A desmosome (/ ˈ d ɛ z m ə ˌ s oʊ m /; [1] [2] "binding body"), also known as a macula adherens (plural: maculae adherentes) (Latin for adhering spot), is a cell structure specialized for cell-to-cell adhesion. A type of junctional complex, they are localized spot-like adhesions randomly arranged on the lateral sides of plasma membranes.
Adjacent epithelial cells are connected by adherens junctions on their lateral membranes. They are located just below tight junctions. Their function is to give shape and tension to cells and tissues and they are also the site of cell-cell signaling. Adherens junctions are made of cell adhesion molecules from the cadherin family. There are over ...
Tight junctions feature the localization of both JAM-1 and JAM-3, and JAM-3 is localized exclusively at tight junctions. [3] The role of JAM-1 in tight junction biology is to function through mediation partly due to the localization of the Par-αPKC complex at adherens junctions during junction creation. [3] Once the tight junction is formed ...
Thus, E-cadherin forms adherens junctions that connect the actin cytoskeletons of neighbouring cells. Adherens junctions are the primary force-bearing junctions between epithelial cells and are fundamentally important for maintaining epithelial cell shape and for dynamic changes in shape during tissue development.
