CC -!- FUNCTION: Actin- and myosin-binding protein implicated in the
CC regulation of actomyosin interactions in smooth muscle and nonmuscle
CC cells (could act as a bridge between myosin and actin filaments).
CC Stimulates actin binding of tropomyosin which increases the
CC stabilization of actin filament structure. In muscle tissues, inhibits
CC the actomyosin ATPase by binding to F-actin. This inhibition is
CC attenuated by calcium-calmodulin and is potentiated by tropomyosin.
CC Interacts with actin, myosin, two molecules of tropomyosin and with
CC calmodulin. Also plays an essential role during cellular mitosis and
CC receptor capping. Involved in Schwann cell migration during peripheral
CC nerve regeneration. {ECO:0000269|PubMed:17200138}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton
CC {ECO:0000250|UniProtKB:P13505}. Cytoplasm, myofibril
CC {ECO:0000250|UniProtKB:P13505}. Cytoplasm, cytoskeleton, stress fiber
CC {ECO:0000250|UniProtKB:P13505}. Note=On thin filaments in smooth muscle
CC and on stress fibers in fibroblasts (nonmuscle).
CC {ECO:0000250|UniProtKB:P13505}.
CC -!- TISSUE SPECIFICITY: High-molecular-weight caldesmon (h-caldesmon) is
CC predominantly expressed in smooth muscles, whereas low-molecular-weight
CC caldesmon (l-caldesmon) is widely distributed in non-muscle tissues and
CC cells. Not expressed in skeletal muscle or heart.
CC -!- DOMAIN: The N-terminal part seems to be a myosin/calmodulin-binding
CC domain, and the C-terminal a tropomyosin/actin/calmodulin-binding
CC domain. These two domains are separated by a central helical region in
CC the smooth-muscle form.
CC -!- PTM: In non-muscle cells, phosphorylation by CDK1 during mitosis causes
CC caldesmon to dissociate from microfilaments. Phosphorylation reduces
CC caldesmon binding to actin, myosin, and calmodulin as well as its
CC inhibition of actomyosin ATPase activity. Phosphorylation also occurs
CC in both quiescent and dividing smooth muscle cells with similar effects
CC on the interaction with actin and calmodulin and on microfilaments
CC reorganization. CDK1-mediated phosphorylation promotes Schwann cell
CC migration during peripheral nerve regeneration.

CC ECO:0000269|PubMed:7876150}.
CC -!- SIMILARITY: Belongs to the caldesmon family. {ECO:0000305}.
