Anti-Caldesmon, HMW (h-Caldesmon) (Smooth Muscle Marker), clone CALD1/820

Formulation: Purified Ab with BSA and Azide at 200ug/ml. Cellular Localization: Cytoplasm, Cytoskeleton, Myofibril, Stress fiber. Positive Control: Blood vessels in all tissues, smooth muscle or leiomyosarcoma., Uterus. Chromosome Location: 7q33. Protein Function: 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 plays an essential role during cellular mitosis and receptor capping. Involved in Schwann cell migration during peripheral nerve regeneration (By similarity) [The Uniprot Consortium]
