Caldesmon

Caldesmon is a is_associated_with::protein that in humans is encoded by the CALD1 is_associated_with::gene.

Caldesmon is a is_associated_with::calmodulin binding protein. Like is_associated_with::calponin or troponin, caldesmon tonically inhibits the ATPase activity of myosin in smooth muscle.

Immunochemistry
In diagnostic is_associated_with::immunochemistry, caldesmon is a marker for is_associated_with::smooth muscle differentiation.
