This antibody reacts with the High Molecular Weight (120-150 kDa) and a Low Molecular Weight (71-80 kDa) forms of Caldesmon, an actin interacting and Calmodulin binding protein found in smooth muscle and other cell types.
The caldesmon protein is involved in contraction, cell movement, shape change, exocytosis and endocytosis. It is an actin interacting and calmodulin binding protein found in smooth muscle and other cell types. Caldesmon occurs in both a high molecular weight (120-150 kDa) and a low molecular weight (61-70 kDa) form, depending on the tissue in which it is located. Caldesmon plays a major role in the regulation of smooth muscle and non-muscle contractile events.Synonyms: CAD, CALD1, CDM
