Function

Muscle-specific type III intermediate filament essential for proper muscular structure and function. Plays a crucial role in maintaining the structure of sarcomeres, inter-connecting the Z-disks and forming the myofibrils, linking them not only to the sarcolemmal cytoskeleton, but also to the nucleus and mitochondria, thus providing strength for the muscle fiber during activity (PubMed:25358400). In adult striated muscle they form a fibrous network connecting myofibrils to each other and to the plasma membrane from the periphery of the Z-line structures (PubMed:24200904, PubMed:25394388, PubMed:26724190). May act as a sarcomeric microtubule-anchoring protein: specifically associates with detyrosinated tubulin-alpha chains, leading to buckled microtubules and mechanical resistance to contraction. Required for nuclear membrane integrity, via anchoring at the cell tip and nuclear envelope, resulting in maintenance of microtubule-derived intracellular mechanical forces (By similarity). Contributes to the transcriptional regulation of the NKX2-5 gene in cardiac progenitor cells during a short period of cardiomyogenesis and in cardiac side population stem cells in the adult. Plays a role in maintaining an optimal conformation of nebulette (NEB) on heart muscle sarcomeres to bind and recruit cardiac alpha-actin (By similarity).

Activity summary

Desmin also referred to as Desmin 20 is an intermediate filament protein with a molecular weight of approximately 53 kDa. Primarily found in muscle cells desmin provides structural integrity to cells being an important component of the cytoskeleton. Desmin expression is highly specific to cardiac skeletal and smooth muscle tissues and it can be detected using desmin marker techniques like desmin IHC (Immunohistochemistry). Desmin staining or desmin stain methods are commonly employed in diagnostic labs to visualize this protein within tissue samples.

Biological function summary

Desmin plays a significant role in maintaining cellular architecture by anchoring organelles such as nuclei and mitochondria within the cytoplasm. It associates with other proteins to form desmin intermediate filament networks which facilitate force transmission and maintain mechanical integrity. This protein does not operate in isolation but is part of a larger complex of cytoskeletal elements that reinforce muscle cell shape and resilience. Its interactions and binding with other cytoskeletal components confirm its essential role in muscle structure.

Pathways

Desmin links closely to the cell structure and function pathways providing stability during muscle contraction processes. It interacts with other proteins including actin and tubulin within the cytoskeleton network ensuring coordinated responses to mechanical stress. Specifically desmin integrates into pathways related to the maintenance of the sarcomere structure thereby connecting to additional important proteins like myosin and dystrophin which collectively uphold muscular function and integrity.

Associated diseases and disorders

Desmin mutations can lead to myopathies such as desmin-related myopathy (DRM) or cardiomyopathy where the structural disruptions result in abnormal muscle function. These conditions typically manifest as muscle weakness or cardiac abnormalities. Furthermore its relationship to the sarcomere suggests interactions with proteins like dystrophin in muscular dystrophies where desmin integrity critically influences disease progression and severity. Understanding desmin's link to such disorders underpins its role as a diagnostic marker and a potential therapeutic target in muscle-related diseases.

The cells were fixed with 100% methanol (5 min), permeabilized with 0.1% Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1% PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab203422 at a 1/100 dilution (shown in green) and Alexa Fluor® 647 Anti-Tubulin antibody [YOL1/34] - Microtubule Marker ab195884, Rat monoclonal to alpha Tubulin (Alexa Fluor® 647), at a 1/250 dilution (shown in red).
