Abstract
Antibodies were raised against a calmodulin-binding CaMg-ATPase (Ca2+-transport ATPase) from smooth muscle. The binding of these antibodies to a number of related Ca2+-transport ATPases was studied. Antibodies to the calmodulin-binding ATPase from porcine antrum (stomach) smooth muscle do not only bind to this CaMg-ATPase, but also to the corresponding enzyme in porcine erythrocytes. However, they do not bind to the CaMg-ATPase from sarcoplasmic reticulum of porcine skeletal muscle. The binding of these antibodies to the CaMg-ATPase of smooth muscle, does not inhibit the enzyme activity.Keywords
