CNN3
Function
Thin filament-associated protein that is implicated in the regulation and modulation of smooth muscle contraction. It is capable of binding to actin, calmodulin and tropomyosin. The interaction of calponin with actin inhibits the actomyosin Mg-ATPase activity.
Sequence Similarities
Belongs to the calponin family.
Tissue Specificity
Expressed in both non-smooth muscle tissues as well as smooth muscle tissues.
Alternative names
Calponin-3, CNN3
