ca·ten·in

(ka-tēn'in),
Cytoplasmic molecule that serves as a link between cadherins and the cytoskeleton of cells, allowing the formation of adherent junctions. There are two types: β-catenin, which is linked to the cadherin itself and α-catenin, which associates with actin microfilaments.
[L. catena, chain, + -in]

JUP

A gene on chromosome 17q21 that encodes a major cytoplasmic protein common to both submembranous plaques of desmosomes and intermediate junctions. JUP forms distinct complexes with cadherins, belongs to the catenin family and contains a distinct amino acid motif known as armadillo repeat.

Molecular pathology
JUP mutations are associated with Naxos disease.

ca·ten·in

(kă-tē'nin)
Cytoplasmic molecule that serves as a link between cadherins and the cytoskeleton of cells, allowing the formation of adherent junctions. There are two types: beta-catenin, which is linked to the cadherin itself, and alpha-catenin, which associates with actin microfilaments.
[L. catena, chain, + -in]

catenin

a PROTEIN initially characterized because of its association with the ACTIN of the CYTOSKELETON, where it acts as a bridging protein between CADHERIN and actin.

The sections were stained for the following markers: Pancytokeratin (Leica Bond AE1/AE3), NSE (Leica Bond 22C9), CD56 (Leica Bond CD564), Vimentin (Leica Bond V9), CD10 (Leica Bond 56C6), progesterone receptor (Leica Bond 16), [beta] catenin (Leica Bond 17C2), chromogranin (VENTANA), synaptophysin (Leica) and CD99 (VENTANA O13).
Membranous staining for Pan Cytokeratin, CD56 and CD10 and nuclear staining for PR and [beta] catenin was taken as positive.
The [alpha], [beta], p, and [gamma] catenins play important roles in intercellular signal transduction.

He completely gave up chicken and mutton which are Beta catenin sources [17].
The catenin, p120ctn, is a common membrane-associated protein in various epithelial and non-epithelial cells and tissues.
We found that the absence of CLASP2 or pi20 catenin in epidermal stem cells caused a loss of their adhesion, and therefore the structure of these cells," said Shahbazi.
1,2) The integrity and morphology of epithelial units is maintained by E-cadherin and its undercoat proteins, the catenins ([alpha], [beta], and [gamma]]g), which are associated with the cytoplasmic domain of E-cadherin.
Like LCIS, PLCIS exhibits loss of E-cadherin staining (Figure 2, D) and cytoplasmic redistribution of p120 catenin, and hence these 2 stains are useful to confirm a suspected diagnosis.
4] After examination of the expression of cadherins and [Beta]-catenin, the distribution pattern of cadherin and catenin expression (plasma membrane, cytoplasm, or nucleus), intensity of staining, and percentage of cells stained were recorded.
If so, are they catenins found in those junctions, or where you see the cell-cell staining?
For Ecadherin--an adhesion molecule forming complexes with catenins at epithelial cell-cell adherens junctions that is lost during epithelial-to-mesenchymal transition--positive membrane staining is only seen in the epithelial cells, not the stromal cells.
