Protein Structure
UniProt Annotation
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, troponin C and tropomyosin. The interaction of calponin with actin inhibits the actomyosin Mg-ATPase activity.
Subcellular Localization
Disease Associations
Tissue Specificity Smooth muscle, and tissues containing significant amounts of smooth muscle.
