Anti-Caldesmon, HMW (h-Caldesmon) (Smooth Muscle Marker), recombinant antibody, clone rCALD1/7266

Formulation: Purified Ab WITHOUT BSA and Azide at 1.0mg/ml. Cellular Localization: Cytoplasm, Cytoskeleton, Myofibril, Stress fiber. Positive Control: Blood vessels in all tissues, smooth muscle or leiomyosarcoma. Skeletal muscle. 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]
