  2. Cell junction - Wikipedia

    en.wikipedia.org/wiki/Cell_junction

    Hemidesmosomes form rivet-like links between cytoskeleton and extracellular matrix components such as the basal laminae that underlie epithelia. Like desmosomes, they tie to intermediate filaments in the cytoplasm, but in contrast to desmosomes, their transmembrane anchors are integrins rather than cadherins. [8]

  3. Hemidesmosome - Wikipedia

    en.wikipedia.org/wiki/Hemidesmosome

    Hemidesmosomes can be categorized into two types based on their protein constituents. Type 1 hemidesmosomes are found in stratified and pseudo-stratified epithelium.Type 1 hemidesmosomes have five main elements: integrin α6 β4, plectin in its isoform 1a, i. e. P1a, tetraspanin protein CD151, BPAG1e, or bullous pemphigoid antigen isoform e, and BPAG2 (also known as BP180 or type 17 collagen). [2]

  4. Cell adhesion - Wikipedia

    en.wikipedia.org/wiki/Cell_adhesion

    In multicellular organisms, bindings between CAMs allow cells to adhere to one another and creates structures called cell junctions. According to their functions, the cell junctions can be classified as: [1] Anchoring junctions (adherens junctions, desmosomes and hemidesmosomes), which maintain cells together and strengthens contact between cells.

  5. Desmosome - Wikipedia

    en.wikipedia.org/wiki/Desmosome

    The inner dense plaque, also about 15–20 nm in length, contains the C-terminus end of desmoplakin and their attachment to keratin intermediate filaments. Desmoplakin is the most abundant part of the desmosome, [7] as it operates as the mediator between the cadherin proteins in the plasma membrane and the keratin filaments. Desmoplakin has two ...

  6. Intercellular communication - Wikipedia

    en.wikipedia.org/wiki/Intercellular_communication

    When the membranes of two animal cells are close, they may form special types of cell junctions, which come in three broad types: occluding junctions (such as tight junctions and septate junctions), anchoring junctions (such as adherens junctions, desmosomes, focal adhesions, and hemidesmosomes), and communicating junctions (such as gap ...

  7. Epithelium - Wikipedia

    en.wikipedia.org/wiki/Epithelium

    Cell junctions are the contact points between plasma membrane and tissue cells. There are mainly 5 different types of cell junctions: tight junctions, adherens junctions, desmosomes, hemidesmosomes, and gap junctions. Tight junctions are a pair of trans-membrane protein fused on outer plasma membrane.

  8. Basal cell - Wikipedia

    en.wikipedia.org/wiki/Basal_cell

    Basal cells are bound to each other by desmosomes, and to the basal lamina of the basement membrane by hemidesmosomes. These junctions help to create one tightly bound, continuous tissue layer that can endure mechanical stress and effectively function as a connection between the basement membrane and remaining epithelial tissue. [4]

  9. Plectin - Wikipedia

    en.wikipedia.org/wiki/Plectin

    Plectin has been revealed to localize to the desmosomes and in vitro studies have shown that it can form bridges between the desmosome protein, desmoplakin and intermediate filaments. [19] In hemidesmosomes plectin has been shown to interact with the integrin β4 subunits of the hemidesmosome plaque and function in a clamp-like manner to link ...
