A. Western blot analysis on HeLa cell lysates using anti-Phospho-Caldesmon (pT730) RabMAb (Cat. #AJ1117d), 1:10,000 dilution. Cells were either (A) untreated (B) treated with Calyculin A.
Actin- and myosin-binding protein implicated in the regulation of actomyosin interactions in smooth muscle and nonmuscle cells (could act as a bridge between myosin and actin filaments). Stimulates actin binding of tropomyosin which increases the stabilization of actin filament structure. In muscle tissues, inhibits the actomyosin ATPase by binding to F-actin This inhibition is attenuated by calcium-calmodulin and is potentiated by tropomyosin. Interacts with actin, myosin, two molecules of tropomyosin and with calmodulin. Also play an essential role during cellular mitosis and receptor capping Involved in Schwann cell migration during peripheral nerve regeneration (By similarity)
Tissue Specificity
High-molecular-weight caldesmon (isoform 1) is predominantly expressed in smooth muscles, whereas low-molecular- weight caldesmon (isoforms 2, 3, 4 and 5) are widely distributed in non-muscle tissues and cells. Not expressed in skeletal muscle or heart
Cellular Localization
Cytoplasm, cytoskeleton (By similarity). Cytoplasm, myofibril (By similarity). Note=On thin filaments in smooth muscle and on stress fibers in fibroblasts (nonmuscle) (By similarity)
