des·mo·some

(dez'mō-sōm),
A site of adhesion between two epithelial cells consisting, in each cell, of a dense attachment plaque with associated intermediate filaments and transmembrane proteins known as cadherins.
[desmo- + G. sōma, body]

desmosome

/des·mo·some/ (dez´mo-sōm) a circular, dense body that forms the site of attachment between certain epithelial cells, especially those of stratified epithelium of the epidermis, which consist of local differentiations of the apposing cell membranes.

desmosome

[dez′məsōm]
Etymology: Gk, desmos, band, soma, body
a small, circular, dense area within the intercellular bridge that forms the site of adhesion between certain epithelial cells, especially the stratified epithelium of the epidermis. Also called macula adherens.

des·mo·some

(des'mō-sōm)
A site of adhesion between two epithelial cells, consisting of a dense attachment plaque separated from a similar structure in the other cell by a thin layer of extracellular material.
Synonym(s): macula adherens.
[desmo- + G. sōma, body]

desmosome

a thickened zone in the cell membrane of adjacent eukaryote cells.

desmosome

A site of adhesion between two adjacent cells, such as in the corneal epithelium. It consists of a small, dense body in which the two halves are separated by an intercellular gap filled with extracellular substance. The basal cells are attached at irregular intervals to the underlying basement membrane (adjacent to Bowman's layer) by hemidesmosomes (one half of a desmosome). Thus, scraping off the epithelium usually leaves fragments of the basal cells attached to the basement membrane.

desmosome

the 'spot-welds' which provide one of the structural units that bind epithelial cells together. Half units are called hemidesmosomes.

desmosome core
a dense core of glycoproteins filling the space between cells which are adhered by desmosomes.
half d's
structures which provide points of adhesion to anchor cytoskeletal elements to basal cell membranes. Called also hemidesmosomes.

Along with observations from other labs demonstrating that the [Alpha]-catenin binding site on plakoglobin overlaps with that for desmosomal cadherins, these data suggest a possible means of achieving cytoskeletal specificity.
But in cells coexpressing DP-NTP, desmosomal cadherins and plakoglobin were redistributed into punctate structures containing DP-NTP.
Transfection of desmosomal cadherins leads to stabilization of this endogenous plakoglobin.
Several laboratories have mapped plakoglobin binding sites for classic and desmosomal cadherins.
