General description
Calmodulin from bovine takes up a dumb-bell-structure. Two calcium binding EF hand loops, antiparallel β-sheet and three α-helices comprises a lobe. It has a central helix connecting the lobes. Calmodulin can bind four calcium molecules in a cooperative interaction pattern.
Application
Calmodulin bovine has been used inin vitro phosphorylation assay of recombinant retinoic acid-inducible gene I protein. It has also been used in the endoprotease Glu-C proteolysis and deamidation studies.
Biochem/physiol Actions
Ca2+ binding protein that is required for activation of cyclic nucleotide-dependent phosphodiesterase. It is also a cofactor/activator of nitric oxide synthase, calcineurin, and many kinases including ATPase, myosin light chain kinase, and CAM kinase I, II, and III. It mediates ryanodine receptor activation by cyclic ADP-ribose and is involved in intracellular Ca2+ homeostasis.
Calmodulin from bovine undergoes conformational changes upon calcium binding. It binds to sphingosylphosphorylcholine and inhibit calcineurin and phosphodiesterase enzymes.
