'''NMR SOLUTION STRUCTURE OF APO CALMODULIN CARBOXY-TERMINAL DOMAIN'''<br />


==Overview==
==NMR SOLUTION STRUCTURE OF APO CALMODULIN CARBOXY-TERMINAL DOMAIN==
We have determined the solution structures of the apo and (Ca2+)2 forms of, the carboxy-terminal domain of calmodulin using multidimensional, heteronuclear nuclear magnetic resonance spectroscopy. The results show, that both forms adopt well-defined structures with essentially equal, secondary structure. A comparison of the structures of the two forms shows, that Ca2+ binding causes major rearrangements of the secondary structure, elements with changes in inter-residue distances of up to 15 A and, exposure of the hydrophobic interior of the four-helix bundle. Comparisons, with previously determined high-resolution X-ray structures and models of, calmodulin indicate that this domain is structurally autonomous.

== Function ==
[https://www.uniprot.org/uniprot/CALM_BOVIN CALM_BOVIN] Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca(2+). Among the enzymes to be stimulated by the calmodulin-Ca(2+) complex are a number of protein kinases and phosphatases. Together with CEP110 and centrin, is involved in a genetic pathway that regulates the centrosome cycle and progression through cytokinesis (By similarity).

== Publication Abstract from PubMed ==
We have determined the solution structures of the apo and (Ca2+)2 forms of the carboxy-terminal domain of calmodulin using multidimensional heteronuclear nuclear magnetic resonance spectroscopy. The results show that both forms adopt well-defined structures with essentially equal secondary structure. A comparison of the structures of the two forms shows that Ca2+ binding causes major rearrangements of the secondary structure elements with changes in inter-residue distances of up to 15 A and exposure of the hydrophobic interior of the four-helix bundle. Comparisons with previously determined high-resolution X-ray structures and models of calmodulin indicate that this domain is structurally autonomous.
