Rabbit anti CALD1 antibody recognizes caldesmon, also known as CDM and CAD.

CALD1 is an actin-binding protein which is also able to bind myosin, calmodulin and tropomyosin, and inhibits the actin-activated myosin ATPase by blockin actin-myosin interaction. As a "side-binder" of actin, CALD1 stabilizes the filamentous structure of actin and is therefore profoundly involved with assembly and organization of the actin cytoskeleton (Wang 2008). CALD1 negatively regulates cell proliferation and migration and release of metalloproteinase, and is itself regulated by a range of kinases at multiple phosphorylation sites (Hai 2015). It is found in smooth muscle and non-muscle cells. In smooth muscle, CALD1 appears to regulate smooth muscle contraction and cell motility (Eves et al. 2006). CALD1 has been observed to be downregulated in many cancer cell types and has been identified as a potent suppressor of cell invasion, regulating podosome/invadopodium formation of cancer cells (Yoshio et al. 2007).
