In cardiac muscle, Cadherin-2 is an integral component in adherens junctions residing at intercalated discs, which function to mechanically and electrically couple adjacent cardiomyocytes. (wikipedia.org)
Intercalated discs conduct electrochemical potentials directly between the cytoplasms of adjacent cells via gap junctions . (wikidoc.org)

The structural integrity of these tissues requires extensive cell-cell adhesion and interactions mediated by the adhesive junctional complexes consisting of the adherens junctions and desmosomes [ 2 - 5 ]. (oncotarget.com)
Adherens junctions are a ubiquitous type of intercellular junction and are present in both epithelial and non-epithelial cells [ 3 , 6 ], whereas desmosomes are adhesive junctions that confer tensile strength and resilience on cells and are present not only in epithelial cells but also in non-epithelial cells that endure mechanical stress, such as cardiac muscle and meninges [ 7 .

Adjacent2
The sarcolemmas from adjacent cells bind together at the intercalated discs. (lumenlearning.com)
The cells of the heart muscle are equipped with three different types of extracellular cells intersections intermittently "point" desmosomes and "sheet" desmosomes (or adjacent fascia) - located in a specialized part of the plasma membrane, the intercalated disk. (mormonwoman.org)
These light and dark bands are sarcomeres which are highly organized structures of actin, myosin, and proteins. (labtestsguide.com)
Vertically oriented Z-line (disc) proteins anchor the thin filaments and divide the myofibrils into functional contractile units called sarcomeres . (humanbiomedia.org)

Fibers4
Microscopically, the discs appear as folded, dark-staining lines that run perpendicular to the direction of cardiac muscle fibers. (humanbiomedia.org)
In contrast, the skeletal muscle is composed of multinucleated muscle fibers and has no inserted discs. (mormonwoman.org)
The heart muscle has branched fibers, one nucleus per cell, striations and intercalated discs. (mormonwoman.org)
A homozygous mutation of DSG2 p.F531C was identified as the pathogenic mutation in patients with arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) involving both ventricles, as a result of widened and impaired intercalated discs, interrupted myocardial fibers, and abnormally hyperplastic interstitial fibers, collagen fibers, and adipocytes. (cusabio.com)
Mitochondria1
a) Cardiac muscle cells have myofibrils composed of myofilaments arranged in sarcomeres, T tubules to transmit the impulse from the sarcolemma to the interior of the cell, numerous mitochondria for energy, and intercalated discs that are found at the junction of different cardiac muscle cells. (lumenlearning.com)
Skeletal muscle3
The T tubules are only found at the Z discs, whereas in skeletal muscle, they are found at the junction of the A and I bands. (lumenlearning.com)
Why Are The Intercalated Discs Not In Skeletal Muscle? (mormonwoman.org)
Heart muscle and skeletal muscle both have striations because of their structure, but the inserted disks are only found in the heart muscle. (mormonwoman.org)
Cells7
This transmission of impulses makes cardiac muscle tissue similar to nerve tissue, although cardiac muscle cells are notably connected to each other by intercalated discs . (wikidoc.org)
Individual cardiac muscle cells are joined together at their ends by intercalated discs . (humanbiomedia.org)
Intercalated disk allows the cells in the heart muscle to contract like a wave, allowing the heart to act as a pump . (mormonwoman.org)
Heart cells are special among muscle types because they are connected to each other by intercalated disks - structures that are it only occurs in the heart Muscle cells. (mormonwoman.org)
At the heart, the heart muscle cells (myocytes) are connected end-to-end by structures known as intercalated disks. (mormonwoman.org)

Cadherin-2 complexed to catenins has been described as a master regulator of intercalated disc function. (wikipedia.org)
In agreement with this, mice with ablation of N-cadherin in adult hearts via a cardiac-specific tamoxifen-inducible Cre N-cadherin transgene showed disrupted assembly of intercalated discs, dilated cardiomyopathy, impaired cardiac function, decreased sarcomere length, increased Z-line thickness, decreases in connexin 43, and a loss in muscular tension. (wikipedia.org)
The syndrome is caused by changes in the structure and function of certain cardiac ion channels and reduced expression of Connexin 43 (Cx43) in the Right Ventricle (RV), predominantly in the Right Ventricular Outflow Tract (VSVD), causing electromechanical abnormalities. (bvsalud.org)
