Calmodulin binding proteins in human erythrocyte membranes.
Human erythrocyte membranes reveal different calmodulin-binding proteins determined by a 125I-calmodulin gel overlay procedure. Beside the well-established Ca2+-transport ATPase, other proteins (205, 91, 72 and 42 kDa) bind calmodulin in a Ca2+-dependent manner. Two proteins of the human erythrocyte membrane are able to bind calmodulin only in the absence of Ca2+. One of them (76 kDa) is probably an integral, the other (240 kDa) a peripheral protein.
