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 ...
English: the diagram shows a cell-cell junction called adherens or zonula adherens. It also contains the main proteins involved in it. It also contains the main proteins involved in it.

The band-type of adherens junctions is associated with bundles of actin filaments that also encircle the cell just below the plasma membrane. Spot-like adherens junctions called focal adhesions help cells adhere to extracellular matrix. The cytoskeletal actin filaments that tie into adherens junctions are contractile proteins and in addition to ...
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.
While in the adherens junction, cadherins recruit β-catenin molecules onto their intracellular regions [clarification needed]. β-catenin, in turn, associates with another highly dynamic protein, α-catenin, which directly binds to the actin filaments. [39] This is possible because α-catenin and cadherins bind at distinct sites to β-catenin ...
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.
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 ...
Adherens junctions are made of cell adhesion molecules from the cadherin family. There are over 100 types of cadherins, corresponding to the many different types of cells and tissues with varying anchoring needs. The most common are E-, N- and P-cadherins. In the adherens junctions of epithelial cells, E-cadherin is the most abundant. [1]
