  • Title: Calmodulin-binding proteins of Tetrahymena microsomal membranes.
    Author: Nagao S, Nozawa Y.
    Journal: Comp Biochem Physiol B; 1985; 82(4):689-93. PubMed ID: 3937657.
    Abstract:
    Tetrahymena calmodulin radioiodinated with a lactoperoxidase method retained full ability to activate Tetrahymena guanylate cyclase. Binding of [125I]calmodulin to Tetrahymena microsomal membranes was Ca2+-dependent and inhibited by excess unlabeled calmodulin or trifluoperazine. When Triton X-100-solubilized microsomes were chromatographed on calmodulin Sepharose, several proteins were found to interact with calmodulin in a Ca2+-dependent manner.
