| 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 play an essential role during cellular mitosis and receptor capping.

| Subcellular Location |
Cytoplasm, cytoskeleton {ECO:0000250}. Cytoplasm, myofibril {ECO:0000250}. Note=On thin filaments in smooth muscle and on stress fibers in fibroblasts (nonmuscle). {ECO:0000250}.
|
| Tissue Specificity |
High-molecular-weight caldesmon (h-caldesmon) is predominantly expressed in smooth muscles, whereas low- molecular-weight caldesmon (l-caldesmon) is widely distributed in non-muscle tissues and cells. Not expressed in skeletal muscle or heart.
