Calponin is a 34kD polypeptide that interacts with actin, tropomyosin, and calmodulin. It is involved in smooth muscle contraction mechanism and is restricted exclusively to smooth muscle tissue. Anticalponin has been found to be useful in differentiating benign sclerosing lesions of the breast from carcinoma. Calponin positivity has also been noted in malignant
myoepithelioma and pleomorphic adenoma of salivary gland origin, as well as angiomatoid malignant fibrous histiocytoma.
